Emerson Micro Motion 1600 - 13.4.1 Set up pressure compensation using the display

You must be able to supply pressure data to the transmitter.
13.4.1 Set up pressure compensation using the display
Procedure
1. Choose Menu → Configuration → Process Measurement → Pressure.
2. Set Units to the pressure unit used by the external pressure device.
3. Enter Flow Factor for your sensor.
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 −0.0002% per psi, enter +0.0002 % per PSI.
4. Enter Density Factor for your sensor.
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/cm
3
/PSI.
5. Set 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.
Option
Description Setup
Polling The meter polls an external
device for pressure data.
a. Set Pressure 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 Primary HART masters
will be on the network. A field
communicator is not a HART master.
Poll as Secondary No other Secondary 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.
Digital
communications
A host writes pressure data
to the meter at appropriate
intervals.
a. Set Pressure Source to Fixed Value or Digital
Communications.
b. Perform the necessary host programming and
communications setup to write pressure data to the meter
at appropriate intervals.
Postrequisites
The current pressure value is displayed in the External Pressure field. Verify that the value is correct.
