N635 Metering of Natural Gas and Associated Liquids

Course Facts

Course Code:
1 days
0.8 Continuing Education Units
8 Professional Development Hours
Certificate Issued Upon Completion


Natural gas is metered about four times between the wellhead and the gas transmission system.   In the past, virtually all metering of natural gas in the field and in the plants was done with the orifice meter.  Nowadays there is a great variety of meters to choose from for gas and liquid flow measurement. The standards that are followed for the installation of meters, the recording of the flow parameters and the calculation of the flow rates are explained.  The latest issue of the AGA 3 report is covered.

Accurate metering is the foundation for equitable plant products and revenue allocation.

The operation and application of new types of meters are explained:
        • Coriolis meter
        • Vortex shedding meter
        • Ultrasonic meter
        • V-Cone meter

Duration and Training Method

One classroom day providing .8 CEU (Continuing Education Credits) or 8 PDH (Professional Development Hours)

Participants will learn to

• Estimate basic properties of produced fluids for metering
• Select meter for specific measurement application
• Check orifice meter installation, operation, maintenance
• Calculate flow rate with orifice meter
