New Smart Meter Connections – The new integral smart meter (8-wires) is connected directly to the transmitter’s PWA and is mounted to the electronics module assembly inside the electronics housing. The new integral smart meter is designed for the ST 3000 Release 300 transmitter and provides functionality not available with other smart meter designs.

NOTE:Only one smart meter should be installed integrally to the transmitter.

ATTENTION	Be aware that the RMA 300 remote meter does not have custom and
	flow units capability like the new smart meter. Therefore, if you use a
	local smart meter that is configured to display readings in custom or
	flow units in conjunction with an RMA 300 remote meter, the readings
	of the two meters will be in different units.
