Emerson Micro Motion 4200 - Configure Pressure Measurement Unit; Configure Velocity Measurement Unit

Effect of Temperature Damping on process measurement
Temperature Damping affects all processes and algorithms that use temperature data from the internal
sensor RTD.
Temperature compensation
Temperature compensation adjusts process measurement to compensate for the effect of temperature on
the sensor tubes.
API referral
Temperature Damping affects API referral process variables only if the transmitter is configured to use
temperature data from the sensor. If an external temperature value is used for API referral, Temperature
Damping does not affect API referral process variables.
Concentration measurement
Temperature Damping affects concentration measurement process variables only if the transmitter is
configured to use temperature data from the sensor. If an external temperature value is used for
concentration measurement, Temperature Damping does not affect concentration measurement process
variables.

Pressure Measurement Unit controls the measurement unit used for pressure. This unit must match the unit
used by the external pressure device.
Pressure data is used for pressure compensation and for API referral. The device does not measure pressure
directly. You must set up a pressure input.
Procedure
Set Pressure Measurement Unit to the desired unit.
• Default: psi
4.7.1 Options for Pressure Measurement Unit
The transmitter provides a standard set of measurement units for Pressure Measurement Unit. Different
communications tools may use different labels for the units. In most applications, set Pressure Measurement
Unit to match the pressure measurement unit used by the remote device.
