Fire Flow Switch Picture as bellow,
Ultrasonic flow meter and flow switch adopt velocity difference method to design general meters for urban water supply pipelines, fire fighting and household metering, which solves the problems of high initial flow rate and non-metering for small flow rate of traditional flow meter and is suitable for various industrial sites. When used as a flow switch, the alarm flow signal can be set at will through the data communication interface. When the flow rate of the flowmeter is greater than the set flow rate value, an on signal will be output to switch on the motor power switch to start the pump. When the flow rate is less than the set flow rate value, an off signal will be output for turning off the power supply of the motor to achieve the purpose of turning off the pump. Using ultrasonic flow measurement technology, diameter pipe body design, no pressure loss, no mechanical rotating parts, reduce the cost of enterprise water supply. The reliability is high, and the measurement is not interfered by magnets. It has a variety of output functions, is connected with wireless transmission, and can form a monitoring system to monitor the operation of instruments and pipe networks.
