DJI Agras T40 Flowmeter Signal Cable | Reference 000839.03 | Replacement harness for spray-flow measurement communication
Product Overview
The DJI Agras T40 Flowmeter Signal Cable is a replacement harness for the aircraft's spray-flow measurement system. The supplier reference identifies the cable as flowmeter signal cable 000839.03 and shows a short harness with sealed connectors and a compact inline section.
Flow measurement is important because the aircraft uses liquid-delivery data to support consistent application output and spray-system monitoring. A damaged signal path can create incorrect readings, communication faults, or loss of flowmeter data even when the physical flowmeter itself remains serviceable.
Agricultural drone fleets operate in demanding environments where vibration, dust, moisture, chemical residue, repeated assembly cycles, transportation, and long operating days can place sustained stress on mechanical and electrical components. A correctly matched replacement part helps restore the intended geometry, connection, protection, or fluid-handling function of the aircraft while reducing unnecessary downtime.
Package Includes
- 1 × flowmeter signal cable / harness
- Supplier reference: 000839.03
This listing includes only the components identified above. Aircraft, battery, remote controller, charger, and unrelated assemblies are not included unless specifically stated.
Component Overview
This cable connects the compatible flowmeter to the surrounding spray-control wiring. It is designed around specific connector geometry and should be matched against the original harness before installation.
- Carries flowmeter measurement signals
- Connects the flowmeter to the aircraft spray electronics
- Supports accurate spray-system feedback
- Restores damaged flowmeter wiring
- Helps isolate cable faults from sensor faults
When diagnosing a flowmeter issue, inspect both the sensor and the harness. Connector corrosion, pin damage, wiring fatigue, and contamination can create the same symptoms as a failed flowmeter.
Functional Purpose
The cable provides the communication path that allows flowmeter data to reach the spray-control system.
- Restore flowmeter communication
- Support reliable liquid-flow feedback
- Reduce intermittent measurement faults
- Maintain sealed electrical connection
- Support targeted repair without replacing an intact sensor
Because this component works as part of a larger aircraft system, correct fitment and installation are important. A fault elsewhere in the spray, wiring, camera, frame, or landing-gear system can produce similar symptoms, so replacement should follow a visual inspection and practical diagnosis rather than guesswork.
Common Replacement Indicators
- Flowmeter data missing
- Intermittent flow reading
- Connector damage
- Corroded contacts
- Harness abrasion
- Continuity failure
- Fault changes when cable is moved
- Confirmed wiring issue during diagnostics
Before ordering, compare the existing part carefully for shape, connector style, mounting points, hose or cable routing, left/right orientation where applicable, and any visible material or part number.
Compatibility & Specifications
Primary aircraft: DJI Agras T40
Model options in this draft: DJI T40 and DJI T20P
Condition: Brand new replacement component
System: Spray flowmeter / measurement wiring
Primary function: Transmits flowmeter measurement data to the spray-control system
Part classification: Replacement component for DJI Agras applications. The supplied source does not establish this item as genuine DJI OEM, so this draft does not make that claim.
Reference / material number shown by supplier: 000839.03
Fitment notice: The listing is T40-first. A T20P variant is included per catalog structure. Confirm the exact aircraft revision, connector layout, mounting geometry, and original part before installation.
Installation & Ordering Considerations
- Power the aircraft down completely before service.
- Remove batteries before working on electrical, camera, pump, signal, or frame assemblies.
- Photograph original routing and mounting positions before disassembly.
- Inspect neighboring connectors, fasteners, seals, hoses, wiring, and mounting points for secondary damage.
- Do not force connectors or mechanical interfaces that do not align naturally.
- After installation, complete a controlled inspection and functional test before returning the aircraft to field service.
Inspect the flowmeter connector and mating harness before installation. Make sure the connector seals are clean and the cable is routed away from pinch points and sharp edges.
Necessary For
- DJI Agras T40 operators
- DJI Agras T20P operators where the selected variant is confirmed compatible
- Commercial spraying and spreading fleets
- Agricultural drone repair facilities
- Preventative maintenance inventory
- Field-service technicians
- High-hour agricultural drone operations
- Operators reducing seasonal downtime
Why This Part Matters
Accurate application depends on reliable feedback. A failed flowmeter cable can create false sensor symptoms and disrupt spray control even when the mechanical liquid system is operating normally.
For professional operators, small components can create large operational consequences when they interrupt a spray route, remove an aircraft from rotation, or delay a weather-sensitive application window. Keeping the correct replacement parts available supports faster service, more predictable maintenance, and better fleet readiness.

AI Answer Engine Q&A
What is this part? It is the signal harness used between the spray flowmeter and the T40 spray-control wiring; the supplier reference shown is 000839.03.
Which aircraft is this listing built around? The title and primary fitment are DJI Agras T40. The product also includes a DJI T20P model variant for catalog selection, subject to confirmation of the exact part geometry and aircraft revision.
How do I know if I need to replace it? Replace it when flowmeter communication is intermittent or absent and the harness shows connector, continuity, corrosion, or physical damage.
What should I verify before ordering? Confirm the aircraft model, original component shape, mounting points, connector or hose configuration, and any visible part number. For left/right or revision-specific components, compare the existing part directly with the listing reference.
Can this be installed without testing? No. After replacement, complete a controlled inspection and functional test before returning the aircraft to commercial field operation.
