"Digital flow control valve is composed of the automatic spool, the manual valve core, and the display portion. The display portion consists of a flow valve movement, sensor transmitter, and electronic calculator display portion.

It works extremely complicated. The impeller in which the water flows through the valve, the water flow impacts the impeller, the impeller rotation and the sensing transmission, so that the sensor issues the signal number proportional to the flow rate, the flow signal is sent to the electronic calculator through the wire, pass the calculator After calculation, the microprocessor is processed, its flow value is displayed.

The manual valve core is used to adjust the flow value, depending on the display value. The automatic spool is used to maintain a constant flow, i.e., when the pipe network pressure changes, the automatic spool will automatically open the large shutter small valve opening under the action of the pressure to maintain the setting flow value.
