For detailed information regarding wiring of the HART output channel, please refer to: FGM
160 – HART Output Interface Specification [6].
6.2.5.6 Pulse/Frequency/Level Output
As an option, the FGM 160 can be configured with one passive pulse/frequency/level output.
This output can be configured in three different ways:
Pulse output configuration.
o The pulse signal can be used e.g. to interface an external totalizer/counter.
Frequency output configuration.
o The frequency signal can be used as an alternative to analog current loop
output.
Level output configuration.
o This signal can e.g. be used for alarm or status output.
