Flow Sensor PM-1/4-B

The flow sensor is designed to read the flow of water or other liquid with a flow rate of 0.35 to 3 L per minute. High sensitivity allows for the detection of even small liquid flows. The sensor sends a corresponding pulse signal. It has a body made of brass, a water impeller and a Hall sensor. When water flows through the impeller, it moves the impeller shaft. Its speed changes at different flow rates. The Hall sensor sends a corresponding pulse signal. It can be applied to water heaters, automatic water dispensers mounted on 1/4-inch diameter pipe or other industrial automation projects.Flowmeter PM-1/4-B

Application

  • Used to read the rotation of water or liquids
  • Can be used in various DIY projects.

 

Dimensions and wiring diagram

When water flows through the flowmeter body, the impeller shaft is moved - the sensor generates the corresponding X pulse signal (specified in the technical data). The number of pulses is proportional to the water flow rate. The pulses can be converted to user-friendly values such as milliliters, liters, liters/min using meters.
