There is an effect on the reference K-factor due to a diameter change of the flow tube
bore with temperature. The effect is -0.3% of flow rate per +55°C / +100°F increase in
temperature. The flowmeter will automatically recompute a flowing K-factor when
process temperature is entered in the database fluid definition.

Note: When operating at ambient temperatures below -29°C / -20°F, it is important to
maintain a minimum loop voltage of 15.75 VDC to maintain remote configurator
communications capability.
