Explanation
Setting the pressure process data for Pitot
tube measurement and standard data for
volumetric flow rate measurement.
Absolute pressure existing in the process.
The entered absolute pressure value is
included in the Pitot tube calculation.
Temperature existing in the process. The
entered temperature value is included in the
Pitot tube calculation.
Humidity existing in the process. The entered
humidity value is included in the Pitot tube
calculation.
The Pitot tube correction factor depends on
the shape of the Pitot tube (see operating
instructions of the Pitot tube).
The entered correction factor has a direct
proportional effect on the volumetric flow
rate.
The entered value is included in the Pitot
tube calculation.
