General Flow Sensor – PASPORT

Product Code: PS-2222


The General Flow Sensor determines the fluid velocity of air or water by measuring the difference in pressure between the two input tubes. The Venturi Tube or Pitot Tube must be connected to the General Flow Sensor to collect data. The type of fluid (air or water) being used is selected using PASCO software. Venturi and Pitot Tubes sold separately.


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


  • Transparent PVC allows you to see the fluid flowing through the pipes. Quick disconnects have shut-off valves so fluid doesn’t leak and one sensor can be moved from one connection to another.
  • Works in air or water.
