General Flow Sensor with Venturi – PASPORT

Product Code: PS-2225


The General Flow Sensor determines fluid velocity in air or water by measuring the difference in pressure between the two input tubes. Either the Venturi Tube or the Pitot Tube must be connected to the General Flow Sensor. The type of fluid (air or water) being used is selectable in the software.


  • The Venturi Tube is used in a pipe network that carries water or air. The Pitot Tube is used in an open water channel or in air.
