Configure process measurement
Calibration Pressure
is the pressure at which your sensor was calibrated, and therefore defines the
pressure at which there will be no pressure effect.
Calibration Pressure
for your sensor is provided on
the sensor calibration sheet. If the data is unavailable, enter
20
PSI.
5.
Decide how pressure data will be provided to the transmitter, and perform the required setup.
• If you will poll an external pressure device, set up polling for pressure.
• If you will use a static pressure value, set
Pressure Units
to the units you are using, enter
External Pressure
, and ensure that polling for pressure is disabled.
• If you will use digital communications or a direct analog current to write pressure data to the
transmitter, set
Pressure Units
to the units to be used and ensure that polling for pressure
is disabled. Then ensure that the appropriate value is written to transmitter memory at
appropriate intervals.
• If you will use an external measurement device, configure the mA input to
External Pressure
.
You must also enable
External Pressure Compensation
and set the
Pressure Units
to the units set at
the external measurement device.

The petroleum measurement parameters control the values that will be used in the transmitter’s
petroleum measurement application.
The petroleum measurement parameters include:
•
API Table Type
•
Thermal Expansion Coefficient
(TEC) (if required by
API Table Type
)
•
Reference Temperature
(if required by
API Table Type
)
Restriction
The petroleum measurement parameters are available only if the petroleum measurement application has
been purchased and is enabled on your transmitter.
Procedure
1.
Select
API Table Type
.
2.
If you set
API Table Type
to
53A
,
53B
,
53D
, or
54C
, set
Reference Temperature
to the appropriate value for
your application. Enter the value in °C.
3.
If you set
API Table Type
to
6C
,
24C
, or
54C
, set
Thermal Expansion Coefficient
to the appropriate value
for your application.
4.
(Optional) Set the temperature unit configured on the transmitter to the temperature unit used by
your API reference table.
