Flow sensor PM-1/2-B
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 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 1/2-inch diameter tube or other industrial automation projects.
