The volume corrector determines the volume flow under standard conditions of the medium to be measured based on the volume measurement in the operating state and its temperature and pressure . The amount now determined is given in standard cubic meters . By multiplying by the specific calorific value , the energy can now also be determined.
In gas networks , the volume in the customer's lines is determined by a gas meter that records the volume. If the pressure deviates significantly from the usual network pressure, a volume corrector is installed that corrects to the standard conditions.
