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.
