For low (distribution) pressure including validation and poor pressure investigation, the standard single-channel OSPREY PL can monitor pressure between 0 - 145psi.
For medium/intermediate pressure measurements, including governor feed and MP/IP maintenance operations, the bolt-on MCA (Multi Channel Adapter) can monitor pressure between 0 - 145psi.
OSPREY can be configured to take readings and log data at pre-set intervals – which will determine the overall battery lifetime. As a typical example, the OSPREY memory can store over 10 years of data at 6 second reads and 6 minute logging. The read and log rates are completely configurable and can be easily changed via the PressureTrac software.
Incident Evaluation Mode
Gas networks have a duty to respond to reports of low gas pressure, the cause of which must be investigated, determined and resolved. The quicker this is done, the more satisfied the consumer will be with the service provided and, in the case of a leak, the less gas will be lost. There is an obvious health and safety incentive to resolve such issues as soon as practicable.
There are numerous potential causes for low or fluctuating pressure including pipework design, environmental effects such as freezing temperatures or water ingress, increased demand elsewhere in the network, regulator failure, etc. In cases where the cause of poor pressure is not evident, monitoring the gas supply to the affected and surrounding premises can provide essential information, enabling the results of investigative and remedial work to be confirmed immediately.
Abriox has therefore designed into OSPREY a unique Incident Evaluation Mode (IEM™). Once configured in IEM, the OSPREY automatically transmits all pressure data to its software HQ every 12 hours, so that fluctuations can be remotely monitored and compared at one or more locations.
Compared to the old manual system of data logging over a 1-2 week period, downloading the data and then analyzing it after the event, OSPREY provides a real-time, dynamic picture of the investigation. This typically enables incidents to be cleared up in hours and days, rather than in weeks!
A large gas network typically deals with thousands of gas escapes per year. The ISO 14001 international standard of environmental excellence has a rigorous approach to environmental management. Gas networks accredited to this standard will continuously benchmark their environmental performance with the aim of reducing natural gas emissions (“shrinkage”) from their activities and assets.
Nationally hundreds of millions of £/$ are spent on maintenance and shrinkage annually. With a more accurate recording system and data stream, there is the potential for financial savings to be made through more effective pressure management.
OSPREY offers the opportunity to reduce costs associated with maintenance and shrinkage. Even a very small reduction in either area will generate a massive payback on the capital cost of the system.
Working in the Field
PressureLink is a communications interface for use with the OSPREY range of pressure monitors. It acts as an intrinsically safe barrier between the OSPREY and un-assessed equipment, such as a laptop PC.
PressureLink allows calibration, maintenance and data download from OSPREYs in the field. This provides technicians the ability to carry out required work without having to completely remove the OSPREY and send back to the service team, saving time, costs and helping improve your carbon footprint.
Once downloaded to a laptop, the data may be imported into the PressureTrac software for evaluation.
PressureTrac® is a dedicated web-based pressure management software system for displaying, recording and exporting pressure data from the range of OSPREY® Pressure and Control Monitors. It also provides full remote configuration of all OSPREY monitors directly. Data is displayed both graphically and tabulated for quick and easy viewing, along with accurate GPS positioning of all devices in the field.
