Abstract: This paper will examine the economics of low pressure metering, fixed pressure factor metering, and instrumented pressure delivery metering. A procedure is detailed for determining the total cost of each method by including the after-tax capital costs and the present value of the after-tax operating costs over 20 years. From this the most economical metering can be selected, allowing for special operating conditions or customer requirements which must be met. The minimum capital costs for stations with design loads of 2.0 MCFH through 16.0 MCFH are presented and tables for converting future operating cost cash flows into present dollar values are provided. When total costs are evaluated, it is found that usually low pressure metering should be given first consideration when designing a new station. When pressure delivery is required, fixed pressure factor metering is usually the next most economical.
