Interfaces
As a standard, FLOWSIC30 comes with loop-powered 4..20 mA output. The current loop
supports digital HART
®
communication for setup and diagnosis of the gas meter. The inter
-
face can be used also to transmit additional measurement data. Optionally, FLOWSIC30
can be ordered with an additional Modbus RS485 interface.
