Custody transfer flow metering of natural gas is one of the most critical processes for consumers. Monitoring this process allows the consumer to better control expenses, since the accuracy of custody transfer flow metering of natural gas directly affects the total costs of the company.
The natural gas consumer can significantly reduce the risks of overpayment to the Supplier for consumed gas by implementing measures for improvement of accuracy of the inlet custody transfer gas flow metering, as well as to take control of this process, since more accurate and modern gas flow metering equipment will be on the Consumer's side.
Our solutions, based on high-reliable and well-proven technologies, have been successfully implemented and have proven their effectiveness in practice at various industrial enterprises of the Russian Federation, including the electric power industry.
COMPARISON OF DIFFERENT GAS FLOW MEASUREMENT TECHNOLOGIES
ULTRASONIC FLOW METERS
- The lowest measurement error is +/-0.3%
- Highest performance and dynamic range
- No pressure drop
- Low maintenance cost due to the absence of moving parts
- Calibration interval is 4 years
- Extensive diagnostic capabilities
CONSTRICTION DEVICES (ORIFICE PLATES)
- Measurement error – +/-0,5…1 % depending on the installation conditions
- Low performance and small dynamic range
- Presence of a pressure drop
- Requires regular maintenance
- Lack of maintenance negatively affects the measurement error
- Calibration interval is 1 year
- Lack of diagnosis
TURBINE METERS
- Measurement error of +/- 0,5%
- Performance and dynamic range are better than those of the diaphragm, but worse than ultrasound
- Presence of a pressure drop
- High maintenance costs due to the presence of moving parts and the need for regular lubrication
- Calibration interval is 1 year
- Lack of diagnosis
