Short description

The volume conversion device EK280 is an explosion-protected electronic
device that takes the volume of gas determined by an external meter at
measurement conditions to calculate the volume at base conditions and
therefore the energy portion of the respective gas volume.
Furthermore, the gas flow of a pipeline can be monitored, recorded and
transmitted by means of the recording function, the signal inputs and
outputs, as well as the serial and optical data interfaces of the device.
Recording the necessary state variables for this purpose takes place via an
externally or internally connected pressure sensor as well as a temperature
sensor. An alphanumeric display and a keyboard on the front panel of the
device serve as the control elements for the EK280.
