Digital flowmerter detects the differential pressure caused by the flow velocity inside the pipe through the combination of a Piitot tube and digital differential pressure gauge and transmitter. The compact and light-weight design allows the flowmeter to be installed on cool and hot water pipes for building air conditioning systems,plant facilities,etc. Digital flowmerter detects the differential pressure caused by the flow velocity inside the pipe through the combination of an Orifice and digital differential pressure gauge and transmitter.The flowmeter applies diverse process connections(screws,flanges,and fit-in)and can be mounted to field pipes compactly.
