Analog input 4 ... 20 mA
An external pressure transmitter, an external temperature
transmitter or a gas analyzer for a density signal can be
connected onto the analog input (4 ... 20 mA). The analog
input measures the current loop value.
— Temperature input for the return for power measurement
— Pressure input for pressure compensation for the flow
measurement of gases and steam
— Concentration of gas for the net metering of methane
(biogas)
— Density for calculating the mass flow

HART 7 communication with remote transmitter
Because the device is designed with two-wire technology, a
pressure or temperature transmitter can also be connected to
the power supply lead (4 ... 20 mA).
The transmitter connected must run in HART burst mode. The
device supports remote transmitters with HART 7
communication.
