Selecting Pressure type from within RealFLO6

From the Sensor and Display Configuration (MVT Configuration), select the required pressure type from within the Static Pressure field.

Pressure Type:

-Absolute Pressure (Atmospheric Pressure will be included in the static pressure measurement)

-Gage Pressure (Determined by user and will be subtracted from the static pressure measurement)

This will determine how you will proceed with the calibration process of your Static Pressure measurement.

-----------------------------------------

NOTE: In RealFLO 6, the user has the option to calibrate the Static Pressure sensors in either Gage or Absolute. A good indication to know which pressure type has been selected is the displayed units in the calibration routine when completing a Static Pressure calibration. If the units are, for example kPaa or psia, the calibration must be done using Absolute Pressure. If the units are kPag or psig, the calibration must be done using Gage Pressure.

When re-zeroing a sensor using Absolute Pressure, you need to know the local Atmospheric Pressure in uncorrected units. This can be measured using a manometer, GPS or an accurate pressure gage. Do not use corrected pressure, as used by weather stations.
