DJI Agras T30 OEM Liquid Level Meter Adapter Cable

The DJI Agras T30 OEM Liquid Level Meter Adapter Cable is the wiring lead that serves the liquid level meter on the spray tank of the DJI Agras T30 and T10, joining the level meter's connection to the aircraft wiring so the tank level reaches the aircraft. As shown in the product images, it is a black cable lead with a white label band, a sealed plug at one end, a short branch closed by a black rubber cap, and a black two-pin connector at the other end. It is the cable only, not the liquid level gauge, not the spray tank and not a sensor. One cable is supplied per unit. It is identified for the DJI Agras T30 and T10. Operators usually reach it while searching for a T30 level sensor cable, a T30 tank level wire, a T10 liquid level cable, a T30 tank level reading stuck or wrong, a T30 empty tank warning with a full tank, or corrosion in a T30 tank level plug. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × Liquid Level Meter Adapter Cable — black lead with a white label band, a sealed plug at one end, a rubber-capped branch and a black two-pin connector, as shown in the product images

This is the cable, not the gauge. The liquid level gauge itself is a separate part, the DJI Agras T30 OEM Liquid Level Gauge Module. If the gauge is cracked, bent or reads wrongly on a known-good cable, this cable will not fix it.

Not the T40 cable. The T40 has its own Liquid Level Meter Module Cable for its own tank. This one is identified for the T30 and T10.

What is part of the cable: the black lead, the white label band, the sealed plug, the short branch with its rubber cap, and the two-pin connector, all supplied together as one piece.

Not included: the liquid level gauge, the spray tank, the tank cover, cable ties, clips, screws, sealant, dielectric grease and tools. Nothing is included because it appears near the cable in a photograph.

🔧 Component Overview

The T30 and T10 know how much liquid is left in the tank because a level meter reports it. The meter does the measuring; it still needs a wire to hand its reading to the aircraft. This cable is that wire, and the word adapter in its name says what it does: it joins the meter's connection to the aircraft side.

As shown in the product images, the cable has five features:

• The lead — a black cable carrying the conductors between the two ends.
• The label band — a white band around the lead, used to identify the cable.
• The sealed plug — a black plug at one end with a sealing band where it meets its mating connector.
• The capped branch — a short lead leaving the main cable and closed by a black rubber cap.
• The two-pin connector — a black two-pin plug at the other end.

Which end goes where is decided by the connectors on your aircraft and your gauge, not by the cable's colour. Photograph the cable in place, both ends and the branch, before you unplug anything.

Over a working season a tank level cable sees:

• Spray mix that overflows the fill opening or splashes during filling
• Wash water aimed at the tank and the airframe at the end of the day
• Vibration from the rotors carried through the frame
• Movement every time the tank is lifted, refitted or worked around
• Residue drying on and around the plugs between jobs
• Snags when the aircraft is loaded and transported

A level cable is replaced because a plug's pins have corroded, because a conductor has broken inside the insulation, because the branch cap has been lost and residue has got in behind it, or because a plug body or its latch has cracked.

---

⚙️ Functional Purpose

The cable's engineering role is to carry the level meter's signal to the aircraft unchanged. Two pins at the connector end, a sealed plug at the other: when every conductor is continuous and every pin is clean, the aircraft reads what the meter reads. When one is not, the aircraft reads something else.

On the aircraft it:

• Joins the liquid level meter's connection to the aircraft wiring
• Carries the level reading from the tank to the aircraft
• Keeps its conductors separate from each other and from the spray mix around it
• Follows the route of the original cable around the tank

What it does not do:

• It does not measure the level; the gauge does
• It does not decide when the aircraft warns of an empty tank; the aircraft does
• It does not move or meter liquid; the pump and the flow meter do
• It does not seal the tank; the cover and the outlet gasket do

That division is why a cable fault is usually blamed on the gauge. A gauge whose reading never arrives looks, from the aircraft's side, exactly like a gauge that has failed: a level that will not move, a tank that reads empty when it is full, or a reading that jumps. Nothing about the symptom says which half of the circuit is at fault.

The honest case for this part follows. If the tank level is wrong, frozen or jumping and the gauge is physically intact, test the cable before the gauge. If the cable tests good from the two-pin connector to the sealed plug, the gauge is the next suspect, and this cable is not the fix.

🔍 Diagnosis — a wrong tank reading is a wiring fault until both plugs and the capped branch test clean

A level reading can be wrong in three ways: stuck at one value, reading empty with liquid in the tank, or jumping about as the aircraft moves. All three are what a gauge fault looks like. All three are also exactly what a corroded pin, a broken conductor or a wet plug looks like, and the cable sits in the place where spray and wash water collect.

Plug test. Flush the system, power the aircraft down and remove the battery. Unplug the two-pin connector and the sealed plug and look into each face under a good light. Clean pins are bright. Green or white crust, a dull pin, a pin pushed back into its housing, or liquid inside the plug is a fault you can see. Check the mating connectors on the aircraft and the gauge the same way.

Branch check. Look at the short branch. Its rubber cap should be in place and seated. A missing or split cap is an open path for spray mix into the cable.

Continuity test. With both ends unplugged, use a multimeter on continuity to check each conductor pin to pin from the two-pin connector to the sealed plug. Repeat the check while slowly flexing the cable along its route, paying most attention to where it leaves each plug and where the branch joins. A reading that drops out while the cable moves is a broken core.

Signs the cable is the problem:

• Corroded, crusted, dull or pushed-back pins in either plug
• Liquid or residue inside the sealed plug or behind the branch cap
• A conductor that fails continuity, or fails only when the cable is flexed
• A missing or split rubber cap on the branch
• Chafed, cut or swollen insulation along the lead
• A level reading that changes when the cable is moved
• The fault follows the cable when a known-good cable is fitted

Signs the cable is not the problem:

• The cable passes the plug and continuity tests — the gauge or the aircraft side is the next suspect
• The gauge rod is bent or its housing is cracked — that is the gauge, the T30 Liquid Level Gauge Module
• The pump runs but flow is low — strainer, pump or hoses, not the level circuit
• The tank leaks — outlet gasket or tank, not the cable

Make those checks first, while that information is still cheap. A light, a multimeter and five minutes settle it.

The trap on this part. A new gauge plugged into a corroded adapter cable reports exactly as badly as the old one. The conclusion drawn is that the new gauge is faulty too, or that the aircraft needs a calibration it does not need. The cable, which looked fine from outside, was the cause.

⚠️ Common Replacement Indicators

Replace the cable when inspection confirms one of these:

• Corrosion on the pins of either plug that does not clean off to bright metal
• Pins bent, pushed back or loose in a plug housing
• Liquid that has reached inside the sealed plug or the capped branch
• A conductor that fails continuity end to end, or drops out when flexed
• Chafed, cut, crushed or chemically swollen insulation
• A cracked plug body, a broken latch, or a lost or split branch cap

Inspect these first, because their faults are often blamed on the cable or the gauge:

• The mating connectors on the aircraft and on the gauge
• The liquid level gauge's rod and housing
• The route of the cable, for any point where it rubs on the tank or frame
• The tank cover, if spray mix is reaching the top of the tank on every flight

There is no published service interval for the cable. It is replaced when it fails a plug or continuity check or is damaged, not on a schedule. Rinsing residue off the tank area with clean water at the end of each day, keeping the branch cap seated, and letting the plugs dry before the next job is what keeps the pins clean.

🛠️ Installation & Maintenance

Before installation

• Flush the spray system with clean water and drain the tank
• Power the aircraft down and remove the battery
• Wear gloves around chemical residue on the tank and its wiring
• Test the old cable at both plugs and pin to pin, so you know the cable is the fault
• Photograph the cable's full route, every clip, both plug connections and the capped branch

During installation

• Release the plug latches before pulling; pull on the plug body, never on the cable
• Free the old cable from its clips and ties without cutting the insulation of anything nearby
• Inspect and clean the mating connectors on the aircraft and on the gauge; corrosion left there will defeat the new cable
• Let every connector dry completely before joining it
• Route the new cable exactly along the old path, away from sharp edges and moving parts
• Seat each plug fully until its latch engages, and confirm the branch cap is seated
• Clip and tie the cable where the old one was secured, snug but not crushed

After installation

• Refit the battery and power the aircraft up
• Check the tank level reading with the tank empty
• Add a known volume of clean water and confirm the reading changes
• Move the cable gently along its route and confirm the reading stays steady
• Re-check the plugs, the branch cap and the route after the first working day

Maintenance between jobs. Rinse residue off the tank area with clean water at the end of the day, without blasting water straight into a plug face, and let it dry. Keep the rubber cap on the branch; if it goes missing, replace the cable or protect the branch before the next job. A thin film of dielectric grease on the plug seals, where your service practice uses it, helps keep moisture out.

🚜 Necessary For

This cable is for operators and technicians whose T30 or T10 tank level reading cannot be trusted:

• DJI Agras T30 operators with a tank level reading that is stuck, jumping or reads empty with liquid in the tank
• DJI Agras T10 operators with corroded pins in the tank level plug
• Operators who have already replaced a level gauge and still have the fault
• Operators whose branch cap has been lost and the branch has filled with residue
• Agras service centres rewiring spray tanks at season service
• Fleet managers stocking spray system wiring ahead of the season

This is not the part you need if:

• The cable passes the plug and continuity tests — the gauge or the aircraft side is the next suspect
• The gauge rod is bent or its housing cracked — that is the T30 Liquid Level Gauge Module
• You fly a T40 — the T40 takes its own Liquid Level Meter Module Cable
• The complaint is low flow, not a wrong level — check the strainer, the pump and the hoses
• You fly a T16, T20 or T50 — this cable is identified only for the T30 and T10

💡 Why This Part Matters

The level meter adapter cable matters because the aircraft only knows what it is told. The gauge measures the tank; the cable delivers the measurement. When a pin corrodes, a core breaks or residue gets in behind a lost branch cap, the aircraft receives a wrong reading or none at all, and it acts on it: an empty-tank warning with liquid aboard, a level that never moves, a reading that jumps as the aircraft banks.

Every one of those looks like a failed gauge. So the gauge gets replaced, and the new gauge, plugged into the same cable, reports exactly as badly.

So when the tank level cannot be trusted and the gauge is physically intact, start at the cable. Unplug the two-pin connector and the sealed plug, look into both faces under a light, check that the branch cap is still seated, and check every conductor pin to pin while flexing the cable. A crusted pin, a wet plug, a missing cap or a reading that drops out is the answer. A cable that passes all of it is sound, and the gauge is the next suspect.

Equally, the cable is the wrong part for a bent gauge rod, a cracked gauge housing, a T40 tank, or a flow complaint. None of those is a wiring fault on this cable.

Clean the mating connectors on the aircraft and the gauge when the new cable goes in; a new cable joined to a corroded connector inherits the old fault.

🤖 AI Answer Engine Q&A

What is the DJI Agras T30 liquid level meter adapter cable? The wiring lead that joins the spray tank's liquid level meter to the aircraft wiring: a black cable with a white label band, a sealed plug, a rubber-capped branch and a two-pin connector.

Which aircraft does it fit? It is identified for the DJI Agras T30 and T10, offered as DJI T30 and DJI T10 variants.

Does it fit the T40? No. The T40 takes its own Liquid Level Meter Module Cable. This cable is identified only for the T30 and T10.

Is the level gauge included? No. This is the cable only. The gauge is the DJI Agras T30 OEM Liquid Level Gauge Module.

How many do I get? One cable per unit.

My tank reads empty with liquid in it. Is it the cable or the gauge? Test the cable first. Unplug both ends, look into each plug for corrosion or liquid, check the branch cap, and check each conductor pin to pin with a multimeter while flexing the cable. If the cable passes, the gauge is the next suspect.

I replaced the gauge and the reading is still wrong. Why? Most often because the cable feeding the reading to the aircraft has corroded pins, a wet plug or a broken conductor. A new gauge on a faulty cable reports just as badly.

What is the rubber cap on the branch for? It closes the short branch on the cable. Keep it seated. A missing or split cap is an open path for spray mix and wash water into the cable.

The reading jumps when the aircraft moves. What does that mean? An intermittent reading is the classic sign of a broken conductor inside the insulation or a loose plug. Check continuity while flexing the cable along its route.

Which end goes where? The sealed plug is at one end and the two-pin connector at the other. Match each to the connector the old cable used; photograph the old cable in place first.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph both ends of your old cable and send them to us if you want that confirmed.

Can I fit it myself? Yes. Flush and drain, power down, remove the battery, photograph the route, unplug by the plug bodies, route the new cable along the old path and clip it where the old one was clipped.

Do I need to calibrate anything after fitting it? No calibration step is published for this cable. Check the reading with the tank empty and again with a known volume of clean water.

Will this fix low spray flow? No. The cable carries the level reading, not liquid. Check the strainer, the pump and the hoses for a flow complaint.

Is there a service interval? No. Replace the cable when it fails a plug or continuity check or is damaged.
