Liquid flow meters
Flow meters are liquid flow sensors equipped with a magnetic turbine and a Hall sensor. The liquid flowing through the housing rotates the turbine, then the Hall sensor reads pulses from the turbine each time it rotates. The number of pulses can be converted into convenient values for use. This can be used to determine the amount and speed of the liquid that has flowed through the sensor. High sensitivity allows detection of even small liquid flows. The sensor sends a corresponding pulse signal. It is made of a polymer body, 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.
