On-site energy measurement equipment has been installed at the locations and it is assumed that if the equipment will operate satisfactorily at these locations, it will operate anywhere. Several Company departments are involved in the used method of energy measurement. Division personnel change the flowmeter charts, temperature charts and gravitometer charts on a regular basis. These charts are sent to the Measurement office for processing. The Measurement Gas Analysis Center changes sample tanks on a regular basis. A process chromatograph which completely analyzes the flowing gas at least every 15 minutes. Southern California Gas Company's entrance into the age of electronic measurement is discussed. Under normal operating conditions the system will monitor volume and energy measurement continuously, storing this data in 15-minute increments. At some regular time, the host computers located at headquarters, will poll the remote terminal unit, and extract the last 24 hours of data for billing purposes.
