PM-9.8-P-N flow sensor
A liquid flow sensor designed to read the flow of water or other liquid at a rate of 0.3 to 10 L per minute. High sensitivity allows detection of even small liquid flows. The sensor sends a corresponding pulse signal. Made of a polymer body, 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 tube with a diameter of 9-8 mm.

Dimensions and connection diagram

When water flows through the body of the flow meter moves the rotor shaft - the sensor generates the 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 - connection diagram Pulse counter CI8 + 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.
