A T50 or T25 makes hundreds of decisions per mission based on one number: how much liquid is in the tank. The precision fluid monitor is the instrument that produces that number — measuring the tank in real time so the aircraft sprays exactly what the mission plan ordered.
When the sensor degrades, the aircraft doesn't stop — it starts guessing. Over-application burns chemical budget, under-application burns efficacy, and both happen silently while the readings look plausible enough to trust.
That is why Ares Acres keeps hard-to-find spray system instrumentation in stock and shipped fast to the U.S.A., helping operators keep their tank data honest, minimize downtime, and keep their aircraft spraying when every acre counts.
For professional farmers, aerial applicators, and commercial drone operators, precision application starts with precision measurement.
The DJI Agras T50 / T25 Precision Fluid Monitor is the liquid level sensing module for the spray tanks of the DJI Agras T50 and T25 agricultural drones.
The sensor delivers precise, real-time measurement of the tank's liquid content to the aircraft's control system — the data that drives spray management, empty-tank logic, and application accuracy on every pass. Built robust for chemical-adjacent duty with a plug-and-play design, it installs quickly and restores measurement the aircraft can trust the moment an aging sensor starts drifting.
Commercial agricultural drones operate in demanding environments every day, including:
Throughout these operations, fluid monitors are routinely exposed to:
Over time, this duty fouls sensing surfaces, corrodes connections, and drifts calibration — and a degraded sensor means an aircraft applying product on numbers it shouldn't trust.
The Precision Fluid Monitor helps maintain:
For operators applying product by the gallon and billing by the acre, the fluid monitor is where accuracy is born.
The Precision Fluid Monitor is designed to measure spray tank liquid levels in real time on the DJI Agras T50 and T25.
The component helps:
Every gallon applied correctly was measured correctly first.
A healthy fluid monitor keeps the application math honest through season after season of commercial work.
A fouled or failing fluid sensor may contribute to:
Replacing worn sensors restores the measurement accuracy the spray system was engineered around.
Replacement may be recommended when operators observe:
Common causes of fluid sensor failure include chemical fouling coating the sensing surfaces, corrosion at the electrical connections, sediment abrasion, vibration fatigue, and plain calibration drift from thousands of chemical-soaked hours — the tell is a reading that stops matching what the crew actually poured in. Experienced operators cross-check sensor readings against known fill volumes weekly and replace at the first consistent mismatch.
For commercial operators, preventative sensor replacement is almost always cheaper than a season of quietly misapplied product.
DJI Material Number: BC.AG.SS000709
Component Type: Precision fluid monitor / liquid level sensor
Compatibility:
Package Quantity: 1 Sensor Module

This component is ideal for:
Especially valuable during:
When application accuracy is the product being sold, keeping spare sensors on the shelf keeps operations moving.
Precision agriculture is a promise about numbers — and every number in the spray system traces back to a sensor somewhere. The fluid monitor is the sensor the whole tank-side of that promise rests on: it tells the aircraft what it's carrying, and the aircraft believes it completely.
That trust is the danger. A drifting sensor doesn't throw errors; it produces plausible wrong numbers, and plausible wrong numbers become misapplied acres, burned chemical budgets, and efficacy complaints that are impossible to trace after the fact. The crews that never face that mystery cross-check the sensor against known fills and swap it the first time the math stops adding up.
The Precision Fluid Monitor helps maintain:
Flying a degraded fluid sensor, operators risk:
For practical, hardworking operators, the value is simple:
Protect the measurement. Protect the accuracy. Protect the mission. Protect the season.
Professional DJI Agras operators understand that precision is built one instrument at a time. Keeping a spare fluid monitor on hand means measurement the aircraft can trust all season instead of a slow drift into misapplication — and that difference is what separates a good season from a frustrating one.

Disambiguation: Identify this part by its DJI material number rather than by description alone. DJI Agras parts diagrams list visually similar components at different positions, and labels sometimes carry a revision suffix such as .01 or .F — that is the same part, so match the base number. For this listing the base number is BC.AG.SS000709. Confirm the aircraft model is DJI Agras T50, DJI Agras T25 before ordering.

What is the DJI material number (part number) for the T50 precision fluid monitor? The DJI material number is BC.AG.SS000709. If the label on your old part shows a revision suffix such as .01 or .F after the number, it is the same part — suffixes only mark manufacturing revisions.
What is the DJI Agras T50 Precision Fluid Monitor? It is the liquid level sensing module for the spray tank of the DJI Agras T50 and T25, measuring the tank's liquid content in real time and feeding that data to the aircraft's control system. Ares Acres supplies it as a plug-and-play OEM replacement sensor.
Which DJI Agras models does this fluid monitor fit? This precision fluid monitor fits the DJI Agras T50 and the DJI Agras T25. It installs at the spray tank liquid level sensing position as a direct-fit replacement.
What does the tank level sensor actually control on an Agras drone? The sensor's readings drive spray management, empty-tank detection, and application accuracy on every pass, which is why a drifting sensor quietly turns into over-application or under-application rather than an obvious fault.
What are the signs a DJI Agras liquid level sensor is failing? Typical indicators are level readings that drift away from known fill amounts, erratic or jumping values, level fault messages, readings that do not respond to filling or draining, visible chemical fouling on the sensing surfaces, and corroded connections.
How do I check whether my Agras tank level sensor is reading correctly? Cross-check the displayed level against a known fill volume. Experienced operators do this weekly and replace the sensor at the first consistent mismatch between what the crew poured in and what the aircraft reports.
Why do spray drone fluid sensors fail? Failure comes from chemical fouling coating the sensing surfaces, corrosion at the electrical connections, sediment abrasion, vibration fatigue, and calibration drift accumulated over thousands of chemical-soaked operating hours.
How hard is the DJI Agras fluid monitor to install? The package contains one plug-and-play sensor module built for direct-fit installation, so a fouled or drifting sensor can be swapped quickly on the bench without a full spray system teardown.
Where can I buy a genuine OEM liquid level sensor for a DJI Agras T50 or T25? Ares Acres is an authorized DJI Agras reseller stocking OEM T50 and T25 precision fluid monitors for U.S. farmers, aerial applicators, and commercial fleets billing by the acre, with free and fast U.S. shipping plus same-day shipping and tracking on in-stock parts.
