JIYI Flow Meter Sensor - High Precision Liquid Flow Rate Telemetry Module for Agricultural Drones
Achieve flawless liquid distribution accuracy with the genuine JIYI Flow Meter Sensor. Custom-engineered for professional agricultural spraying drones, this high-precision sensor monitors the real-time flow rate of fertilizers, pesticides, and herbicides passing through your delivery lines. It interfaces directly with JIYI flight controllers (such as the K3A Pro, K++ V2, and K++ Pro) to enable automated smart dosage adjustment based on the aircraft's ground speed. Built with robust chemical-resistant housings, it prevents uneven crop dusting and chemical waste on every mission.
The JIYI Flow Meter Sensor is a critical component for precision farming operations, serving as the sensory baseline for smart liquid application workflows.
Dynamic Speed-Based Spray Adjustment :
When connected to your JIYI flight controller ecosystem, this flow meter actively feeds micro-milliliter data into the autopilot. This enables automated dose matching: as your agricultural drone speeds up against a headwind or slows down during a turning maneuver, the system instantly ramps the water pump voltage up or down to maintain an absolutely uniform liquid coverage per acre.
Highly Resistant Impeller Assembly :
Commercial crop spraying involves handling highly corrosive chemical mixtures and dense liquid suspensions. This sensor utilizes an advanced internal impeller design molded from industrial polymers that resist chemical expansion, friction wear, and rust, ensuring repeatable sensor calibration across hundreds of spray acres.
Plug-and-Play Flight Controller Integration :
Forget about manual splicing and complicated data link configurations. This module features a factory-terminated wiring harness that plugs directly into the designated sensor ports of your JIYI autopilot hub, sending clear pulse signals that require zero complex calibration mapping within the ground station software.
Ultra-Low Fluid Resistance Design :
The internal passage geometry is highly optimized to allow liquid payloads to flow freely without creating backpressure or reducing pump efficiency. This ensures maximum spray velocity at the nozzle tips while allowing the sensor to capture hyper-accurate real-time fluid readouts.

Frequently Asked Questions :
Q1: How does the JIYI flow meter help save chemicals during field missions?
Ans: It sends precise fluid volume data to the autopilot, allowing the drone to stop the water pumps completely when performing end-of-row turns or moving between waypoints, entirely preventing costly overlapping or overspraying.
Q2: Do I need to calibrate the sensor before using it for the first time?
Ans: The sensor features factory calibration profiles for clean water. However, because different agricultural chemicals have varying viscosities, we recommend conducting a simple fluid test inside the JIYI assistant app to fine-tune the sensor's exact pulse factor.
Q3: Can I use this flow meter with a standard Pixhawk flight controller?
Ans: This sensor is optimized out of the box for the JIYI ecosystem (K3A Pro / K++). To use it with ArduPilot or Pixhawk setups, you must verify pinout wiring schemes and manually calculate the sensor pulse-per-liter value in Mission Planner.
Q4: What maintenance is required to keep the sensor working accurately?
Ans: After concluding your daily spray schedule, always run clean, fresh water through the entire pump and plumbing system for 2 to 3 minutes. This thoroughly flushes out chemical residue, preventing sticky build-ups from jamming the internal impeller.
