Temperature data are used in several different calculations. Micro Motion sensors
always report temperature data to the transmitter. For greater accuracy, you can
configure the transmitter to use a different temperature value.
There are two ways to configure external temperature compensation:
• If the operating temperature is a known static value, you can enter the
operating temperature in the software, and not poll a temperature
measurement device.
• If the operating temperature varies significantly, you configure the
transmitter to poll for an updated temperature value from an external
temperature measurement device. Polling requires HART/Bell 202
communications over the primary mA output.
