1/2 inch Water Flow Sensor SEN-HZ21WA

1/2 inch Water Flow Sensor SEN-HZ21WA 

The SEN-HZ21WA is a compact inline water flow sensor designed to measure the flow rate of water through a 1/2-inch pipe. It uses an internal turbine rotor and a Hall-effect sensor to detect water movement. As water flows, the rotor spins and generates electrical pulses proportional to the flow speed. These pulses can be counted by a microcontroller to calculate the flow rate and total volume of water. The sensor is lightweight, easy to install, and ideal for automation, monitoring, and water management systems.
