4 Design and Function
4.1 FC1 Flow Computer: Functional Description
The FC1 is a process computer, which is mainly used as a flow computer for
natural gas, thus to measure and calculate the gas flow. For more
information on other scopes of application
refer to volume ”Configuration
of Device Software” of the FC1 manual.
If the FC1 is used for flow conversion of gas, various measuring devices
must be connected to the device (gas meter, pressure transmitter, tempera-
ture transmitter and, optional, gas quality measurement device).
The FC1 has different interface options available for each of these measure-
ment device types:
Device Type
Connection Option
gas meter
•
pulse interface for turbine, rotary piston or
other pulse-generating gas meters
•
serial interface for ultrasonic gas meters via
a manufacturer-specific digital protocol
•
interface for gas meters with an encoder
index
pressure transmitter
