EMS Energy Metering System


The EMS2005 (Energy Metering System) device series is used for determining the energy quantity in raw biogas, natural gas, or liquefied petroleum gas.

The following measured quantities can also be determined:

  • Energy quantity
  • Heating/combustion value
  • Wobbe index
  • Specific density
  • Pressure and temperature

To determine the energy quantity, the volumetric flow rate of the gas to be measured is recorded using a gas flow meter. A calorimeter of the CWD series of devices is used to determine the combustion/heating value. A combustion value quantity converter calculates the energy from the revalued standard volume and the measured value from the calorimeter. The calculated energy flow is output to and displayed on the calorimeter.
