The gas network needs robust and reliable remote pressure monitoring solutions throughout at:

  • District Governors to report network pressures
  • Extremity Points for security of supply - to regulate the end point in homes and businesses
  • Validation Points for network modelling - to reduce distribution costs

Determining the pressure means gas escapes can be identified, provides data for network analysis, and enables regulatory requirements and environmental commitments to be met.

 

 

THE PROBLEM

Maintaining the correct pressure is crucial to monitor shrinkage and keep a safe network, against a backdrop of old infrastructure being updated, including the replacement of gas mains and manual data download at some District Governors.

 

THE RISK

Near-real time monitoring of District Governors with alarming at critical level thresholds helps to identify gas escapes which account for up to 95% of shrinkage, meet regulatory compliance and monitor pressure reduction.

 

THE SOLUTION

Using Metasphere’s ATEX-approved Point Blue remote telemetry unit (RTU), with independent External Pressure Transducers, enables gas transporters to maintain the integrity of the gas network.


HOW DOES THE METASPHERE
SOLUTION WORK?

Point Blue RTU can interface with various pressure transducers currently on the market. External pressure transducers are widely used within the oil and gas industries, and connecting Point Blue to one enables the detection of changes in pressure to be monitored in near real-time. At a District Governor the inlet and outlet pressures are monitored, and digital inputs monitor the Slam Shut and DP Filter of the working stream.

Point Blue provides dynamic trending; it logs data every 15 minutes (user-configurable) and feeds this back daily, directly to the top-end system, ensuring both data privacy and speed, with no additional latency. Under alarm conditions it can be configured to capture, dial in and transfer the data much more frequently (eg. once an hour or less) once the pre-set alarm threshold is reached: ‘high high’, ‘high or low’, ‘low low’. This can be reported, enabling a proactive approach to the status of the gas network while only calling upon Point Blue’s battery power when it is most needed.

Metasphere’s Point Blue can also monitor pressure at Pressure Reduction Stations (PRS), at Local Distribution Zones (LDZ) Offtakes / City Gates, at Extremity Points, at Network Validation Points and many more places.
