14.4.2 Set up pressure compensation using ProLink III
Procedure
1. Choose
Device Tools
>
Configuration
>
Process Measurement
>
Pressure Compensation
.
2. Set
Pressure Compensation Status
to Enabled.
3. Set
Pressure Unit
to the unit used by the external pressure device.
4. Enter the
Density Factor
and
Flow Factor
for your sensor.
a) Set
Process Fluid
to Liquid Volume or Gas Standard Volume, as appropriate.
b) Compare the values shown in
Recommended Density Factor
and
Recommended Flow Factor
to the values from the product data sheet.
c) To use the recommended values, click
Accept Recommended Values
.
d) To use different factors, enter your values in the
Density Factor
and
Flow Factor
fields.
The density factor is the change in fluid density, in g/cm
3
/PSI. When entering the value, reverse
the sign.
Example
If the density factor is 0.000006 g/cm
3
/PSI, enter
−0.000006
g/cm3/PSI.
The flow factor is the percent change in the flow rate per PSI. When entering the value, reverse
the sign.
Example
If the flow factor is 0.000004 % per PSI, enter
−0.000004
% per PSI.
5. Set
Flow Calibration Pressure
to the pressure at which your sensor was calibrated.
The calibration pressure is the pressure at which your sensor was calibrated, and defines the pressure at
which there is no pressure effect. If the data is unavailable, enter
20
PSI.
6. Choose the method you will use to supply pressure data, and perform the required setup.
