🇺🇸 U.S.A. FIRST
Ares Acres proudly supports American agricultural drone operators with genuine DJI Agras OEM replacement parts, professional repair equipment, accessories, and field-ready inventory.
FREE & FAST Shipping is included for all U.S. customers.
Precision spraying is a numbers game — and the numbers come from the flowmeter. Every rate the aircraft holds, every gallon-per-acre the operator promises a customer, depends on flow data traveling cleanly from the sensor to the control system. This cable is that data's only road.
A failing signal cable lies before it dies: readings flicker, rates drift, and the aircraft sprays on bad information while everything looks fine from the ground. By the time the fault code appears, acres have already been treated wrong.
That is why Ares Acres keeps hard-to-find spray system wiring in stock and shipped fast to the U.S.A., helping operators keep their flow data honest, minimize downtime, and keep their aircraft spraying when every acre counts.
For professional farmers, aerial applicators, and commercial drone operators, clean signal wiring is what precision actually runs on.

🔧 Component Overview
The DJI Agras T40 - T20P Flowmeter Signal Cable is the flow data wiring for the spray systems of the DJI Agras T40 and T20P agricultural drones.
The cable carries flow measurement data from the flowmeter to the aircraft's control system — the signal the flight controller uses to hold spray rates, track chemical usage, and keep application precise. Built from durable, high-performance materials with a plug-and-play design, it swaps in fast and restores clean data the moment the old cable starts flaking.
Commercial agricultural drones operate in demanding environments every day, including:
- Crop spraying
- Liquid fertilizer application
- Herbicide treatments
- Fungicide applications
- Insecticide spraying
- Orchard operations
- Vineyard spraying
- Precision agriculture missions
- Daily commercial deployments
- Fleet operations
- High-acreage contract work
Throughout these operations, signal cables are routinely exposed to:
- Continuous airframe vibration
- Flex cycling at every connection
- Chemical overspray and mist
- Moisture and humidity
- Connector wear from service cycles
- Pressure-washing and rinse cycles
- UV exposure
- Heat cycling in summer conditions
- Dust and field grit
- Long commercial operating hours
Over time, this duty fatigues conductors, corrodes connectors, and cracks insulation — and a compromised signal cable means flow data the aircraft can't trust.
The Flowmeter Signal Cable helps maintain:
- Accurate flow data transmission
- Precise, stable spray rates
- Reliable chemical usage tracking
- Clean sensor-to-controller signal
- Fast plug-and-play service
- Consistent maintenance standards
- Increased fleet readiness
- Maximum aircraft uptime
- Reliable commercial operation
For operators billing by the acre, honest flow data is the product — and this cable delivers it.
⚙️ Functional Purpose
The Flowmeter Signal Cable is designed to transmit flow measurement data through the spray systems of the DJI Agras T40 and T20P.
The component helps:
- Carry flow data from sensor to control system
- Support precise spray rate control
- Enable accurate chemical usage tracking
- Maintain clean, stable signal quality
- Resist vibration and flex fatigue
- Replace worn, corroded, or intermittent cables
- Restore trustworthy flow readings
- Install plug-and-play in minutes
- Maintain OEM fitment
- Support preventative maintenance
- Reduce preventable data faults
- Increase fleet readiness
- Keep spare wiring field-ready
Precision application is only as accurate as the data feeding it.
A healthy signal cable keeps the flow numbers honest through season after season of commercial work.
A worn or damaged flowmeter cable may contribute to:
- Erratic or flickering flow readings
- Drifting spray rates
- Inaccurate chemical usage data
- Flow sensor fault warnings
- Misapplied product across acres
- Interrupted spraying missions
- Unexpected downtime
- Wasted diagnostic hours
- Reduced fleet reliability
Replacing worn cables restores the data integrity the spray system was engineered around.
⚠️ Common Replacement Indicators
Replacement may be recommended when operators observe:
- Erratic or intermittent flow readings
- Flow sensor fault messages
- Chafed or cracked cable insulation
- Corroded or discolored connectors
- Loose or worn connector fit
- Readings that change with cable movement
- Chemical-related deterioration
- Moisture found at the connectors
- Maintenance inspection findings
- Spray system rebuild projects
- Fleet refurbishment projects
- Preventative pre-season replacement
- Long-term commercial wear
Common causes of signal cable failure include vibration fatigue breaking conductor strands, connector corrosion from chemical mist and moisture, insulation cracking under UV and heat cycling, and flex wear at the routing points — the classic tell is a reading that jumps when the harness is wiggled. Experienced technicians swap the cable first when flow data goes strange; it's the cheapest component in the measurement chain and the most common culprit.
For commercial operators, preventative cable replacement is almost always cheaper than acres treated on bad flow data.

💡 Why This Part Matters
Every contract a spray operator signs is a promise about numbers — rate per acre, gallons applied, coverage delivered. The flowmeter measures that promise, and this cable is how the measurement reaches the aircraft. When the cable degrades, the promise degrades with it.
Bad flow data is expensive in ways that don't show up immediately: over-application burns chemical budget, under-application burns efficacy, and both burn customer trust. The cable that prevents all of it costs less than a single acre of wasted product — which is why sharp fleets keep one in every field kit.
The Flowmeter Signal Cable helps maintain:
- Honest, accurate flow data
- Rates that hold across the field
- Trustworthy usage records
- Fast plug-and-play fixes
- OEM fit and signal quality
- Professional fleet standards
- Increased aircraft uptime
- Reliable commercial performance
- Long-term operational confidence
Flying a degraded signal cable, operators risk:
- Rates drifting on bad data
- Wasted or under-applied chemical
- Flow faults grounding missions
- Wasted diagnostic hours
- Interrupted missions
- Unexpected downtime
- Lost spraying opportunities
- Reduced return on investment
For practical, hardworking operators, the value is simple:
Protect the data. Protect the rate. Protect the mission. Protect the season.
Professional DJI Agras operators understand that precision is built one connection at a time. Keeping spare flowmeter cables on hand means a two-minute swap at the truck instead of a day of chasing phantom flow faults — and that difference is what separates a good season from a frustrating one.
