XML intelligent flow calculation controller, with five instantaneous flow and 18 instantaneous cumulative display, this flowmeter regardless of mass flow, volume flow, can be used. This instrument is controlled by a single chip microcomputer, can directly accept the pulse voltage signal of a flowmeter or the linear voltage and current signal of a secondary transmitter, used to detect the flow instantaneous value and flow cumulative value of various substances, the counting part uses a nine-digit light emitting digital tube display, and is equipped with power protection, when the power supply of the instrument is lost, the original cumulative value can be retained. It has a separate 24V voltage output for the two-wire transmitter. WKJ intelligent flow integration control instrument is suitable for flow integration measurement and control of various fluids, steam, natural gas, general gas, etc.
