Electromagnetic Liquid Flow Sensor With G1/4 Thread Connection For Accurate Fluid Flow Measurement

The Gravity Liquid Flow Sensor G1/4 is a reliable electromagnetic flow measurement sensor designed for accurate monitoring of liquid flow in industrial, laboratory, and automation applications. Built using electromagnetic sensing technology, the sensor delivers stable and precise flow measurements while offering high resistance to electrical interference and mechanical impact. Its robust construction includes an O-ring rubber seal and silicone-sealed outlet to enhance water resistance and ensure long-term operational reliability.

Featuring standard G1/4 threaded connectors, the sensor can be easily integrated into existing fluid systems. The sensor is suitable for measuring the flow of high-concentration and low-viscosity liquids such as water, diesel, engine oil, milk, paint, detergent, and honey, provided the liquid is free from impurities. When connected to Arduino, ESP32, Raspberry Pi, or other microcontroller platforms, it enables real-time flow monitoring for automation, process control, and fluid management applications.
