In this section you define the various procedures for determining the volume correction factors. Normally you perform this activity once. The possible volume correction factor procedures are required for defining the gas procedure.

Volume correction factors are required if the gas billing types are either thermal or according to standard cubic meters.

Different gas meters process the factors for calculating the volume correction factor in different ways:

• Gas meters that do not use a factor

• Temperature compensation gas meters

• Correctors that may or may not use the gas law deviation factor.

The fixed preset values indicate which factors the register uses:

• Neither temperature, nor pressure, nor the gas law deviation factor

• Temperature only

• Temperature and pressure

• Temperature, pressure and the gas law deviation factor

If you use gas billing for residential and non-residential customers, the main volume correction factor procedures used are as follows:

• At least one procedure for the meters required in the Therm.gas bill. field

• A procedure with fixed temperature for residential customers

• A procedure that uses compressibility for large nonresidential customers

Depending on the existing contracts, procedures with either a linear or a weighted weighting key are necessary.

1. Establish which of the standard settings you are able to use.
2. Change or add to the standard settings.
3. To define a new volume correction factor procedure, proceed as follows:
   
   

• In the VCF procedure field, enter the appropriate key.

For certain selections in the volume correction factor procedure you must perform certain activities as follows:

• If you enter a value in the Gas law DevFac. field, a gas law deviation factor is required:

• Activity: Define measured pressures.

• Activity: Define gas law deviation factor per pressure and temperature

• If you set the Fixed temp. indicator, fixed temperatures are required:

• Activity: Define fixed temperature keys

• Activity: Maintain fixed temperature values

• If you do not set the Fixed temp. indicator and you do not select a special procedure, monthly gas temperatures are required:

• Activity: Maintain gas temperatures measured monthly

• If the gas meter does not use pressure (see documentation for the Therm.gas bill. field), and you do not select a special procedure, pressure values are required:

• Activity: Define air pressure areas

• Depending on the entry in the Air pressure field, you either Maintain Monthly Measured Air Pressures or Maintain Annual Measured Air Pressures.
