Research on technology of new measurement remote diagnosis system

Objective Natural gas measurement management is an important certificate to ensure the normal development of natural gas trade and transfer, and it has a great influence on the economic benefits of both natural gas buyers and sellers. It is difficult to find the abnormal positioning of measurement equipment data in real time in practical applications, which leads to accumulated errors in measurement data and may cause large economic losses. Measurement management personnel urgently need practical tools to solve this problem.

Methods Based on the investigation and analysis of the abnormal data sources of the metering equipment, this paper establishes an abnormal data diagnosis indicator system, and based on the real-time monitoring of system data, a new type of measurement remote diagnosis system has been developed.

Results The remote diagnosis system realizes real-time on-line measurement diagnosis. The system issues a diagnostic report to guide on-site maintenance.

Conclusions Using this new metering remote diagnosis system saves the time and cost of metering personnel's on-site travel and troubleshooting, and escorts the stable operation of pipelines.
