Document Type and Number:
Japanese Patent JP4808905
Kind Code:
B2
Abstract:
Determining a gas mixture consumption comprises calibrating a gas meter as the energy measuring device, where the calibration is based on a base gas mixture; and multiplying the measured energy consumption value with a correcting factor which considers the calorific value of the gas mixture. The calorific value is determined by an external unit. An Independent claim is also included for the gas meter used in the process. Preferred Features: Sensor signal values are determined for the calibration depending on the flow rate of a calibrating gas, and stored in the gas meter. The calibrating gas is air or oxygen.
