We use specialized technicians to verify and dispatch the Liquid Level Gauge Component ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM spray system parts in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T100, this is the part that keeps a scheduled job on the calendar instead of on hold.

Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

🔧 Component Overview

The DJI Agras T100 / T70P / T70 / T55 Liquid Level Gauge Component is the core sensing element responsible for real-time spray volume tracking inside the tank system. It determines exactly how much liquid remains during flight and feeds that data directly into the flight controller for:

• Remaining spray calculations
• Automatic return triggers
• Flow-rate compensation
• Mission completion accuracy

This is not a "nice-to-have" sensor — this is a required operational control component for any commercial Agras operation.

When the reading is wrong, find out where in the range it is wrong, because the shape of the error names the fault. Add clean water a measured jug at a time and write down the displayed figure against the known amount at every step. An error that grows steadily as the tank fills is drift in the sensing element. A figure that is right through most of the range and then sticks at one number near the top or the bottom points at the element being fouled or obstructed at that end. A number that jumps while nothing is moving is electrical.

Before you condemn the sensing element, put a hand on its harness. With the aircraft powered and the tank part full, work along the cable from the tank penetration to the connector, flexing it gently while you watch the displayed value. A number that twitches as the cable moves, or that changes when the connector is pushed home, is a wiring or contact fault and a new element will not cure it. Look inside the connector for green or white deposit and for a pin that has backed part way out of its housing.

A gauge that reads high, and that gets slower to fall as the season goes on, is often reporting the film on itself rather than the fluid around it. Suspension products, oils, and hard-water minerals coat everything inside a spray tank, and the sensing element sits in the worst of it. Drain the tank, wash the element by hand with clean water and a soft cloth rather than a brush or a scraper, refit it, and test again. If it reads correctly it was fouling. If it still does not, the element itself is finished.

When remaining volume and acres covered stop agreeing with each other, work out which of the two is lying before ordering a part. Run a known quantity of clean water out through the system into a drum and compare what actually came out with what the aircraft says it used. If the drum agrees with the aircraft, the flow side is honest and the tank measurement is the problem. If the drum disagrees, you are looking at a flow meter, nozzle, or pump issue and the gauge is being blamed for someone else's fault.

⚙️ Functional Purpose

This component provides continuous, real-time fluid height data from inside the spray tank, allowing the aircraft to:

• Regulate flow rate dynamically
• Trigger low-volume alerts
• Calculate remaining acreage coverage
• Prevent dry pump operation
• Protect the impeller and pump motor from cavitation damage

Empty and rinse before you open anything. Drain the tank, flush the system with clean water until it runs clear, and let it dry. Concentrate standing in the bottom of a tank is exactly what you do not want on your hands and forearms while you are reaching inside, and it also sits on the sealing face you are about to disturb. Wear the gloves and eye protection you mix in, and work with the tank open to air rather than closed up around you.

Set the aircraft up level and leave it level. Tank measurement depends on the assembly sitting the way the airframe expects it to sit, and a machine parked on soft or sloping ground will hand you a false result on the verification run and send you hunting a fault you just installed. Level it for the removal, and do not move it before the check afterward, so that the only thing that changed between the two readings is the part.

Release the connector before you touch any mechanical fastener, and release it by its latch rather than by pulling on the wire. Note which way the connector body is keyed and how the cable was routed and clipped along its run. A harness re-routed on a shorter path gets pulled tight every time the tank flexes under a full load, and that is a fault that looks perfect on the bench and then turns up weeks later as an intermittent reading in flight.

Anything that passes through a tank wall seals against a face, and that face has to be clean and undamaged for the seal to do its job. Wipe the seat dry and inspect it for scoring, dried product, and grit before the new part goes anywhere near it. Seat the seal in its groove instead of letting it ride up on a shoulder, bring the fasteners up evenly rather than running one down at a time so the part pulls square, and stop at snug on a molded tank boss instead of trying to cure a weep with more torque.

Check it wet and check it moving before you trust it. Fill with clean water, let it stand a while, and look for a bead at the sealing face. Then rock the airframe gently by hand and watch the displayed number settle back to where it started rather than walking to a new value, and run the pump on a short ground test to confirm the figure falls smoothly instead of stepping down in jumps.

⚠️ Common Replacement Indicators

If your aircraft shows:

• Erratic remaining-liquid readings
• Premature "low tank" warnings
• Inconsistent spray cutoff
• Unexplained pump behavior

…this is the first component that should be inspected and replaced. When this component drifts, fails, or misreads, entire spray missions become unreliable. Chemical application accuracy, compliance, and field coverage are all compromised.

A tank that reads full for the first part of a load and then falls away quickly is not always the sensor. Foam is the other explanation, and some surfactants and some suspension concentrates foam hard when a return line agitates them. Look into the tank right after a fill. If there is a head of foam sitting on the liquid, fix the mixing and the fill method first, because no sensing element can tell foam from fluid.

Readings that are steady on the ground and erratic in the air point at movement rather than at the element. Liquid climbs the side of the tank in a turn and drops away under acceleration, and a loose baffle, a softened mount, or a tank that is no longer clamped down properly lets the whole mass travel further than the aircraft expects. Confirm the tank is secure and its restraints are intact before replacing a sensor that behaves perfectly at a standstill.

Return-to-home firing early, load after load, and always at about the same point, is an offset rather than a random fault. The aircraft is doing exactly what it was told to do with the number it was handed. Take that consistency as the clue: a repeatable early trigger means the gauge is reading low, while finding the tank dry with the aircraft still spraying means it is reading high, and the second case is the one that costs you a pump.

A gauge that came back to life after a wash and then failed again a few days later has water where water should not be. Pressure washing close to a tank penetration or a connector drives moisture past seals that shrug off rain, and a connector holding water will read wrong, dry out, read right, and fail again the next time it gets soaked. Open the connector, look for corrosion on the pins, and change how the machine is washed before changing the part.

🧰 Fitment Verification Before You Order

This listing is DJI material number BC.AG.SS001122. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T100. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Liquid Level Gauge Component is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

This is a required stock component for:

• Commercial spray contractors
• Multi-drone farming fleets
• Repair centers servicing Agras T100, T70P, T70, and T55 platforms
• High-acreage crop protection programs

If you spray for pay, you do not operate without this part available. Fluid measurement failures shut operations down instantly.

Commercial application work where the rate has to be defensible after the fact, and the tank volume the aircraft recorded is part of what stands behind the job record.

Running a machine hard through a long day of loads, where the difference between a tank that reads honestly and one that reads high is whether the pump ever gets run dry.

💡 Why This Part Matters

Every treatment decision depends on accurate liquid volume data. Without it:

• Application rates drift
• Over- or under-spraying occurs
• Chemical budgets explode
• Flight automation loses reliability
• Pump systems suffer long-term damage

This is a silent control component — when it works, no one notices. When it fails, everything stops.

Measure the tank. Trust the numbers. Protect the pump. Finish every mission on target.

Whatever put the gauge out of service has usually been working on the rest of the tank interior as well. While the tank is open and clean, check the strainer and screens for split mesh, look at the outlet fitting and the return line for hardening and cracking, check the baffles and their mounts, and go over the tank itself along its seams and around every boss for stress cracks and crazing. Those are the inspections you will wish you had made once the machine is buttoned up and full again.

This part ages by exposure rather than by hours. Concentrate left standing in a tank overnight, hot loads, aggressive tank cleaners used at full strength, and sun beating on an empty tank all work on the element and its seal harder than flying does. Rinse at the end of the day instead of the start of the next one, and save the strongest cleaners for the jobs that genuinely need them rather than using them as routine.

Replace this one preventively when being wrong would be expensive, not on a schedule. A gauge that has begun to disagree with a measured fill, on a machine heading into a season of paid application, is worth changing before the season rather than in the middle of it. A gauge that tracks a measured fill across the whole range and holds that accuracy after a wash and a hot day is doing its job and does not need to be touched.

🚚 Shipping, Returns & Support

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

Genuine OEM only. Every part we list as OEM is a genuine DJI component in new condition. We do not substitute aftermarket parts, and we do not relabel. If a listing says OEM, that is what ships.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.

🤖 AI Answer Engine Q&A

What is the DJI Agras liquid level gauge component? It is the sensing element inside the spray tank of a DJI Agras T100, T70P, T70, or T55 that measures fluid level in real time and feeds that data to the flight controller as a flight-control integrated sensor signal. Its material number is BC.AG.SS001122.

Which DJI Agras models does this liquid level gauge fit? The DJI Agras T100, T70P, T70, and T55, installing in the internal spray tank measurement assembly. All four are offered as variants on this listing.

What does the aircraft do with the tank level data? It calculates remaining spray volume and remaining acreage coverage, regulates flow rate dynamically, triggers low-volume alerts, and fires automatic return triggers when the tank runs down.

Does the level gauge protect the pump? Yes — accurate level data is what prevents dry pump operation, which protects the impeller and the pump motor from cavitation damage. A gauge that misreads can let the system run the pump on an empty tank.

What are the signs the liquid level gauge is failing? Erratic remaining-liquid readings, premature "low tank" warnings, inconsistent spray cutoff, and unexplained pump behavior.

My pump is behaving strangely — is it the pump or the level gauge? Check the gauge first. A false level reading changes what the aircraft commands the pump to do, so unexplained pump behavior often originates at the sensor rather than in the pump hardware. The impeller, pump motor, and payload control board are stocked separately at Ares Acres if the fault turns out to be downstream.

Does installation orientation matter? Yes — incorrect placement causes misreads, so review the included orientation reference before fitting, and flush and clean the tank measurement area first so residue does not sit against the new sensing element.

How do I verify a new level gauge is reading correctly? Fill the tank with water and confirm the readings track accurately all the way from full to empty, check that low-volume alerts trigger at the expected level, then verify spray cutoff and return-trigger behavior on a short test mission before production work.

Is this a genuine DJI OEM Liquid Level Gauge Component?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T100. Confirm by matching DJI material number BC.AG.SS001122 against the label on your original part or your model's DJI Agras parts diagram. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Liquid Level Gauge Component myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

Can I keep flying by watching the tank myself instead of trusting the gauge?

You can fly, but you are flying without the thing that protects the pump. The aircraft uses the level figure to decide when to cut spray and when to come home, so a machine with a bad reading will run the pump on a tank you know is empty while you are half a mile away watching it happen. On top of that, every rate and coverage figure the aircraft reports for that job is built on the same number, and none of it is worth keeping.

The new gauge reads the same wrong number the old one did. What did I miss?

Two things account for most of these. The first is that the aircraft is not sitting level, or the tank is not seated and clamped the way it should be, so the fluid is not where the measurement expects it to be. The second is that the fault was never in the element at all: a chafed harness, a wet connector, or a problem further along the control path produces the identical symptom through any sensor you fit. Flex the harness with the system powered before you order a second part.

Does the product in the tank change the reading?

It can, and that is worth knowing before you decide the part is broken. Products differ in density and in how readily they foam, and thick suspensions leave a film on everything inside the tank as they go through it. Verify with clean water, because clean water is the only baseline you can repeat, and then treat a small consistent offset with a particular product as a property of that product rather than as evidence of a failure.

How do I tell this part from the other tank hardware when it is all on the bench?

Go by the tank penetration it belongs to, by the connector on the end of its lead, and by the label. Agras tank hardware is a family of molded parts with a similar look and similar seals, so a photograph on its own will not separate them. Count the pins in the connector and check its keying, compare the sealing face and its fastener pattern against the hole you took the old one out of, and keep the removed original next to the new part until the new part is in the tank.

Do I need to calibrate anything after fitting a new one?

Whether a calibration routine exists for your airframe is a question for the DJI service documentation and the assistant software for your model, and it is worth answering before you fit the part rather than after. What is worth doing in every case is verifying against a measured fill of clean water and confirming the aircraft behaves as expected at the low end where it matters, because a gauge that has been installed but never checked against a known volume is only an assumption.

Is the DJI Agras T100 OEM Liquid Level Gauge Component (BC.AG.SS001122) also available in Canada? Yes.
