Name Functions
Optical sensor unit
Measures the speed of light that travels through the measuring gas by
capturing the refractive index. In addition, this unit monitors the flow rates of
the measuring gas and REF gas.
Sonic sensor unit Measures the speed of sound that travels through the measuring gas.
Power terminal unit Supplies power to other units.
This unit relays signals between units, performs contact output, and outputs
4 - 20 mA analog signals and RS-485 (MODBUS) communication signals.
Main controller
Calculates and displays the "Calorific value," "Density," and "WOBBE index"
based on data received from the optical sensor unit and the sonic sensor
unit. Also converts the units of "Calorific value" and "Density."
Checks the operation statuses of other units to ensure normal measurement
and output.
