VK FL-2 Dual-Channel Paddle Wheel Flow Meter – 5–60L/min, PWM Output, IP67 Waterproof for Agriculture Drones

The VK FL-2 Flow Meter is a dual-channel paddle wheel sensor specifically designed for agriculture drone liquid systems. Offering the same measurement precision as high-end models at just one-fifth the cost, it supports simultaneous flow detection for two independent pipelines, making it ideal for dual-pump agriculture drones.

Key Features

• Cost-Efficient & High Accuracy
  ±5% flow accuracy at a fraction of the cost compared to ultrasonic flow meters.

• Dual-Channel Design
  Measures two liquid pipelines independently with PWM signal output (PWM1/PWM2).

• Quick-Release Structure
  Fast cover removal for tool-free impeller cleaning, reducing maintenance downtime and cost.

• Wide Flow Range
  Supports flow measurement from 5–60 L/min, suitable for various spray applications.

• Universal Compatibility
  Pipe interface size (9×13mm) and mounting dimensions match mainstream drone flow sensors for seamless replacement.

• Flexible Installation
  Compatible with both vertical and horizontal setups; supports both forward and reverse flow direction.

• Compact & Durable
  IP67-rated waterproof housing, lightweight (125g), and easy to integrate into drone liquid systems.
