Gravity: Liquid Flow Sensor (G1/4) - liquid flow sensor

Description

Liquid flow sensor with a thread G1/4. It detects rotation by sending a pulse signal and each rotation is approximately 1/540 liter of liquid. The sensor uses a rubber O-ring and silicone sealant on the outlet end to ensure good water resistance. It guarantees high anti-interference and anti-vibration properties, offering reliable performance and long service life. It can be used with microcontrollers to measure the flow of high concentration and low viscosity liquids, such as water, diesel, motor oil, milk, paint, detergent, honey. The module is supplied with the voltage in the range from 3.5 to 24 V. The product Wiki page offers a manual and sample program code.
