Emerson Micro Motion 1600 - Set up temperature and pressure data for API Referral using ProLink III

b) Verify that the referred density range of the selected table is adequate for your application.
4. If you chose a C table, enter Thermal Expansion Coefficient (TEC) for your process fluid.
Acceptable limits:
• 230.0 x 10
-6
to 930.0 x 10
-6
per °F
• 414.0 x 10
-6
to 1674.0 x 10
-6
per °C
5. Set Reference Temperature to the temperature to which density will be corrected in referred density
calculations. If you choose Other, select the temperature measurement unit and enter the reference
temperature.
6. Set Reference Pressure to the pressure to which density will be corrected in referred density
calculations.
Set up temperature and pressure data for API Referral using ProLink III
The API Referral application uses temperature and, optionally, pressure data in its calculations. You must
decide how to provide this data, then perform the required configuration and setup.
Note
Fixed values for temperature or pressure are not recommended. Using a fixed temperature or pressure value
may produce inaccurate process data.
Prerequisites
If you plan to poll an external device, the primary mA Output (Channel A) must be wired to support HART
®
communications.
The pressure measurement must be gauge pressure, not atmospheric pressure.
The pressure device must use the pressure unit that is configured in the transmitter.
If you are using an external temperature device, it must use the temperature unit that is configured in the
transmitter.
Procedure
1. Choose Device Tools → Configuration → Process Measurement → API Referral.
2. Choose the method to be used to supply temperature data, and perform the required setup.
Option
Description Setup
Polling The meter polls an external
device for temperature data.
This data will be available in
addition to the internal RTD
temperature data.
a. Set Line Temperature Source to Poll for External Value.
b. Set Polling Slot to an available slot.
c. Set Polling Control to Poll as Primary or Poll as Secondary.
Option Description
Poll as Primary No other HART
®
masters will be on
the network. A field communicator is
not a HART master.
Poll as Secondary Other HART masters will be on the
network. A field communicator is not
a HART master.
d. Set External Device Tag to the HART tag of the temperature
device.
e. Select Apply.
