🔧 Component Overview

The Water Tank Level Gauge is the liquid-level sensing component in the DJI Agras spray-tank system. It is what tells the aircraft, and through the aircraft the operator, how much liquid is left on board. This is a replacement unit supplied brand new to restore tank-level measurement when the installed sensor assembly is damaged, contaminated, or has been diagnosed as faulty after wiring and connection checks.

It sits in the spray tank itself, in contact with whatever the operator is applying, and connects back into the aircraft through an electrical interface. That puts it in one of the harsher positions on the airframe: wetted by agricultural chemical, cycled wet and dry many times in a working day, and exposed to residue that accumulates on sensing surfaces over a season. The source listing identifies this gauge for the T10, T20P, T25, T40, and T50.

Because tank and sensor revisions vary across the Agras line, the physical interface matters more than the general description. Compare the connector, the probe geometry, and the mounting interface on the gauge you are removing against the replacement before ordering. Two gauges can serve the same function on the same nominal system and still differ in the details that decide whether one drops into the other's place.

⚙️ Functional Purpose

Tank level is operational information. It is what the operator uses to judge remaining spray volume, plan the rest of a pass, and decide when to break off and return to the fill point. The gauge is the source of that information, and everything downstream of it, from the readout the operator watches to the routing decisions made off that readout, depends on the sensing path being accurate.

A level-sensing fault is easy to misread as a larger problem, because it can present while the spray system is mechanically healthy. Pumps still run, nozzles still atomize, liquid still leaves the aircraft. What is missing is trustworthy information about how much is left. Readings may sit fixed while the tank empties, drift away from reality, or drop out intermittently while everything else behaves normally.

The failure modes here are mostly environmental rather than mechanical. Agricultural chemicals, dried residue, corrosion, contaminated connector contacts, and damaged wiring all affect how a sensing component behaves, and any of them can produce symptoms that look identical to a dead gauge. That is why the sensible sequence is to clean and inspect first, confirm the fault follows the gauge rather than the harness or the aircraft electronics, and replace once you know which it is.

⚠️ Common Replacement Indicators

Tank level reading stays fixed while the tank is visibly emptying.

Displayed level is clearly inaccurate against the actual volume in the tank.

Level indication drops out intermittently during a pass.

The reading jumps or fluctuates with no matching change in tank contents.

Visible physical damage to the sensor body or its connector.

Corrosion on the connector contacts or around the sensing area.

Chemical residue or contamination built up on the gauge.

Diagnostic testing isolates the gauge after wiring and connection checks come back clean.

The symptom stays with the gauge after the harness and connections have been cleaned and reseated.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

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 T10 / DJI Agras T20P / DJI Agras T25 / DJI Agras T40 / DJI Agras T50. 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 Water Tank Level Gauge 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.

💵 What Downtime Actually Costs

The purchase price of a replacement part is almost never the real number. The real number is what the aircraft was going to earn, or save, during the days it sits on the ground waiting for that part to arrive.

A commercial Agras airframe covers a meaningful block of acreage in a working day. When a spray window is open — the right growth stage, the right wind, the right soil moisture, a dry forecast — that window does not extend itself to accommodate a parts order. It closes. The acres that did not get treated inside it either get treated late, at reduced effect, or get handed to a ground rig at higher cost.

Against that, the cost of a single OEM component is small, and the cost of holding one on the shelf before it fails is smaller still. Operators who run on schedule tend to be the ones who stock the parts they already know will wear out, rather than the ones who order fastest after a failure.

For the Water Tank Level Gauge, that logic is straightforward: it is an inexpensive component relative to the DJI Agras T10 / DJI Agras T20P / DJI Agras T25 / DJI Agras T40 / DJI Agras T50 it serves, it is a known service item rather than a surprise, and having one in the truck or the shop converts a multi-day grounding into an afternoon of work.

This is also why we ship from U.S. stock rather than drop-shipping from overseas. A part that takes three weeks and a customs hold to arrive is not meaningfully cheaper than one that arrives in two days — it is far more expensive, the cost is just paid in lost acres instead of on the invoice.

💡 Why This Part Matters

Inaccurate tank information costs an operator in ways that never show up as a mechanical failure. Route planning depends on knowing what is left in the tank. When that number cannot be trusted, the operator either starts landing early to check by eye, or keeps flying on an optimistic reading and runs the tank dry partway through a pass. Both cost time inside a spray window that does not extend itself to accommodate them.

Unnecessary landings are the quiet expense. Every extra trip back to the fill point is flight time, battery cycles, and operator attention spent on something the aircraft was supposed to report for free. Across a full day on a large block, a gauge that cannot be trusted turns into a measurable reduction in acres covered, and it does it without ever throwing an obvious fault that would justify pulling the aircraft off the job.

There is an application-quality angle as well. A tank that empties earlier than the operator expected means a section of the field received less than it should have, and that kind of miss is not visible on the day. It shows up later in the crop, when there is nothing useful left to do about it. Restoring the sensing path puts real numbers back in front of the operator, so decisions about coverage and refills come from measurement rather than estimate.

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

Does this gauge control the spray pump?

No. It is a tank-level sensing component. Pump behavior and spray output are controlled elsewhere in the system, so pump-control faults should be diagnosed separately from level-reading faults.

Can chemical residue cause a bad reading without the gauge being broken?

Yes. Contamination around the sensing area or on the connector contacts can contribute to abnormal behavior. Inspection and cleaning should come before replacement, because a gauge that reads badly with residue on it may read correctly once the residue is removed.

How do I tell whether the fault is the gauge or the wiring?

Work from the outside in. Clean and inspect the sensor area and the electrical connection, look for corrosion, contamination, and damaged wiring, and reseat the connector. If the symptom follows the gauge after the harness and connections check out clean, the gauge is the likely cause.

The pumps and nozzles work fine. Can the level gauge still be the problem?

Yes, and that is the common presentation. A level-sensing fault produces inaccurate or unavailable tank readings while pumps and nozzles keep functioning mechanically. Liquid still leaves the aircraft; what is missing is a trustworthy number for how much remains.

What should I compare before ordering?

Compare the connector, the probe geometry, and the mounting interface against the gauge currently installed. Tank and sensor revisions vary across the Agras line, and those three details decide whether a replacement seats and connects, not the general description of the part.

What has to happen to the tank before I replace the gauge?

Drain the tank and clean the area safely for whatever chemical was last run through it. Power the aircraft down and remove the flight battery before disconnecting anything. Working on a sensing component in a tank that still holds product is both a contamination risk and a personal one.

Do I reuse the seals and mounting hardware?

Preserve them during removal and reuse them unless they are damaged or degraded. The gauge sits in a wetted part of the system, so any chemical-contact surface needs to seat correctly on reassembly. Route the sensor as it was originally configured rather than finding a new path for it.

How should I verify the repair before going back to chemical?

Test with clean water first. Fill in stages and confirm the reported level tracks the actual volume as it rises and falls, watch for dropouts, and check for leaks around the gauge before putting product back through the system.

Is this a genuine DJI OEM Water Tank Level Gauge?

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 T10 / DJI Agras T20P / DJI Agras T25 / DJI Agras T40 / DJI Agras T50. Confirm against your model's DJI Agras parts diagram before ordering. 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 Water Tank Level Gauge 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.
