Overview

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

The Venturi Tube has a constriction and two pressure ports with tubing attached. The Venturi Tube is attached to the General Flow Sensor by the matching couplers. The General Flow Sensor measures the difference in fluid pressure between the two different cross-sectional areas and the software does a calculation to convert this pressure difference into a velocity or volumetric flow. The Venturi Tube slip joints are designed to be glued into any 3/4" PVC pipe network..

The Pitot Tube is designed to be placed in the air flow or water flowing in a channel. The General Flow Sensor, connected to the Pitot Tube, measures the pressure difference between the fluid inlet and the static side taps of the Pitot Tube and the software calculates the fluid velocity from the pressure difference.

The fluid type (air or water) and the accessory being used (Pitot Tube or Venturi Tube) are all user selected when using PASCO software for data collection and analysis.

Special Features

  • 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.
