Abstract
Described is a method and a device for more accurate measurement of a gas supply with a gas meter. A consumption-weighted correction factor is determined by weight averaging of a sensor error factor of the gas meter with a consumption profile characteristic of the gas supply location and the measuring signal is converted using the correction factor. Embodiments relate inter alia to: operation of the gas meter as volume, mass or energy meter; formulae for determining the correction factor with sensor error factors and consumption profiles relative to volume, mass or energy; and measuring signal correction in the case of a non-registering or registering gas meter. Advantages are inter alia: subsequent customer-specific measuring signal correction; no additional measuring complexity; and improved measuring accuracy, in particular improved energy measurement by means of compensation for inherent deviations of the energy signal in the vase of heat value variations.
