Gas Flow Monitoring

Production from remote gas wells is fed into pipelines for transportation to central processing stations. Monitoring individual well production rates requires precise mass gas flow measurement, in addition to flow line monitoring for safety concerns.

For accurate mass gas flow calculations associated with custody transfer, typical monitoring stations have an orifice plate with a differential pressure transmitter for flow measurement, a pressure transmitter to monitor flow line integrity and measure static pressure, and a temperature transmitter. Zero and span adjustments on controls are easily made tamperproof to limit access to authorized personnel.
