General-purpose pulse counter. It has one relay output (3A). Ideal for item counting applications using inductive sensors. Dimension 48x48mm.
Description

PM-3/4-B flow sensor

Liquid flow sensor designed to read the flow of water or other liquid with a capacity of 2 to 45 L per minute. High sensitivity allows detection of even small liquid flows. The sensor sends a corresponding pulse signal. Made of copper 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 3/4-inch diameter pipe or other industrial automation projects.

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.
