Flow sensor PM-1/2-S
Liquid flow sensor designed to read the flow of water or other liquid with a capacity of 1 to 30 L per minute. High sensitivity allows detection of even small liquid flows. The sensor sends a corresponding pulse signal. Made of stainless steel, water impeller and 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 a 1/2-inch diameter tube or other industrial automation projects.

Dimensions and wiring diagram

When water flows through the body of the flow meter moves the rotor shaft - the sensor generates a corresponding pulse signal X (specified in the technical data). The number of pulses is proportional to the speed of water flow. Impulses, thanks to meters, can be converted into user-convenient values such as milliliters, liters, liters/min.

Example of application - wiring diagram Pulse counter CA4 + PM flow meter.
This set allows you to measure the volume of liquid. Example: filling tanks with 1.5 l of fluid each tank.

Example of application - connection diagram CI8 pulse counter + PM flow meter.
This set allows both the measurement of the volume of liquid and the number of dosages. Example: filling a series of 10 pieces of tanks with 1.5 l of liquid each tank. When the series of 10 pieces is completed, light notification.
