Micro Motion CDM100P - Configure the Pressure Input; Configure the Pressure Input Using Prolink III

4.4 Configure the pressure input
Pressure data is required for several different measurements. The meter does not measure
pressure. There are several different methods to obtain pressure data.
• Configure the pressure input using ProLink III (Section 4.4.1)
• Configure the pressure input using the Field Communicator (Section 4.4.2)
4.4.1 Configure the pressure input using ProLink III
ProLink III Device Tools > Configuration > Process Measurement > Line Pressure
Overview
Pressure data is required for several different measurements. There are several different
methods to obtain pressure data.
Tip
A fixed pressure value is not recommended. A fixed pressure value may produce inaccurate process
data.
Prerequisites
You must be able to supply pressure data to the meter. The meter does not measure
pressure.
You must be using gauge pressure.
If you plan to poll an external device, the primary mA output must be wired to support
HART communications.
Procedure
1. Choose Device Tools > Configuration > Process Measurement > Line Pressure.
2. Set Pressure Unit to the unit used by the external pressure device.
Restriction
If the API referral application is enabled, the API table selection automatically sets the
pressure measurement unit. Configure the API referral application first, then change the
pressure measurement unit if necessary.
3. Choose the method you will use to supply pressure data, and perform the required
setup.
