Application

AFP Pitot Tube is a measuring meter to be used by such industries like coal mine, metallurgy, railway, and architecture for the ventilation engineering. It can be used in following cases while working together with all kinds of Differential Pressure Meter:

1. Measuring the wind speed of any point in a ventilation system of a mine.

2. Measuring the wind resistance of any section of the ventilation system of a mine.

3. Identifying the performance of the main fanner or local fanner of a mine.

4. Measuring the flux of the methane drainer of a mine

5. Measuring reference wind speed of the air duct for wind meter verifying. 

Working principles

The dynamic pressure value can be detected at the detecting points when the joints of the Pitot tube are connected to the differential pressure meters through a rubber pipe. Based on the theory of hydrodynamics, the relationship between the dynamic pressure value of non-condensable fluid and the wind velocity at wind testing point can be shown by the function below.
