As a compact analysis computer, the Flow Computer RFC 7 essentially fulfils the following three functions:
Depending on the connected devices and the recorded measurement data, the flow computer can be used with different software and parameterisation for the following applications:
- Measurement data logging from gas meters, gas analysers, pressure and temperature sensors and monitoring of measurement data logging.
- Processing of measurement data and calculation of process variables such as standard volume flow, K-number and calorific value using suitable calculation methods for various gas models.
- Archiving and output of the measured values and calculated process variables or visualisation in graphical form, as well as sending alarm and warning messages in the event of limit value violations.
Depending on the connected devices and the recorded measurement data, the flow computer can be used with different software and parameterisation for the following applications:
- -Vol: Status flow computer for determining the K coefficient and the
- standard volume of gas mixtures, such as natural gas and biogas
- -Energy: Calorific value flow computer for determining the K coefficient and
- the energy content of gas mixtures, such as natural gas and biogas
