ZIP-WAY Venturi Tube
ZW09 The venture tube is a differential pressure producing flow device that is used to measure flow rate through a pipe. Pressure difference between the pressure measured at high pressure connection and low pressure connection is proportional to square of the flow rate through the flow device.
