Everything You Need From a Remote Gas Pressure Monitoring System

Gas utilities need to understand the dynamics of gas distribution through their pipeline network from the intermediate pressure entry point at the district governor (regulator) to the low pressure connections to domestic/industrial consumers.  Each gas distribution network operator must carry out regular pressure checks along the distribution network, be it manually or with the aid of a Gas Pressure Monitoring System. Measurement of the pressure of gas at different points in the network therefore provides critical information.

Operationally, pressure is the most important parameter in gas distribution. A minimum pressure (typically 21 mbar in the UK or 7” water column in the US) needs to be delivered to the consumer. If this is not met, there is a risk that gas supply can be lost and/or domestic appliances fail. The consequent disconnection and reconnection process is costly and disruptive – and is always bad for customer relations.

If complaints associated with pressure are received, it is important that these are investigated and resolved rapidly, as any delay increases the risk of problems occurring and also risks losing gas through escapes (“shrinkage”).

By contrast, if gas pressure is too high, it can create leaks in the system that have to be systematically tracked down and fixed. In addition to the obvious safety concerns, natural gas is a greenhouse gas and, when released to the atmosphere without first being combusted, has a 25 times more potent global warming potential than CO2. So it is very important for the environment to keep as much gas inside the pipe network as possible.

Introducing OSPREY® Gas Pressure Monitoring

Abriox has introduced a radically new way to collect and manage gas distribution pressure data.  OSPREY completely eliminates manual data collection of pressure data, saving time and money. It also massively improves the quality of pressure data - leading to gas production savings, improved gas network efficiency and a reduction in greenhouse gas emissions through leakage.

OSPREY is a fully automatic system comprising:

  • Permanently deployed, intelligent monitoring units incorporating GPS for identification of location and precise time synchronization of data

  • Remote communication via GPRS for reports, alarms and data download

  • Integration of the data into a software platform (PressureTrac®) that can be interfaced with the model used by the gas utilities and with their in-house business systems

OSPREY Remote Pressure Monitors (also known as Remote Monitoring Units - RMUs) can be used for:

  • Network validation - the annual process whereby pressure data, recorded at various points, confirms the accuracy of a sophisticated computer model of the gas network. This model is the basis for network planning

  • Investigations of poor pressure – responding to customer calls, monitoring the variations in pressure to the household or industrial premises and assisting in the timely resolution of the complaint

  • System maintenance – ensuring that pressures are maintained at the correct level while work on the gas network is carried out

  • Calculation of average system pressures over long term periods – OSPREY has a minimum 5 year battery life and holds 10 years of data at standard logging intervals

  • Monitoring third party feed-ins to the gas network, such as from bio-methane or fracking

  • Monitoring the intermediate pressure input to district governors (with alternative sensor pressure range 0-10 bar)


The most cost-effective, completely wireless remote monitoring system for the oil, gas, petrochemical pipeline protection industries.



The ability to view system pressures dynamically has immense potential for improving network management, responding to network incidents and feeding directly into average system pressure calculations.

OSPREY gas pressure monitoring system reduces operating costs by improving our customers’ operational efficiency. And even a small reduction in shrinkage through improved pressure management and/or faster resolution of pressure incidents will generate a massive payback on the cost of deployment.  Some of the immediate benefits OSPREY provides include:

Innovative Design

Abriox’s key technical innovation was an on-board GPS module. The geo-positioning benefits of GPS are well known - automatically assigning data to the correct location and ensuring that a logger can always be found and retrieved. Less well known is the highly accurate timing GPS provides, so that each datum is precisely time-stamped. This combination of “time and space” eliminates the need for manual correction, allowing field data to be entered directly into the validation model.

Using this innovative approach, Abriox has been able to:

  • Speed up the deployment process and reduce errors in logger configuration or download.

  • Ensure data is always allocated to the correct location and eliminate the need for paper records to record when a logger is moved between locations.

  • Reduce instances of loggers being lost in the field.

  • Eliminate manual “cleansing” of data, such as corrections for clock drift, BST/GMT errors and node naming issues.

  • Identify the “peak send-out” date and time, with automatic collection of the relevant data.

Everything You Need From a Remote Gas Pressure Monitoring System

OSPREY has major economic, operational, safety and environmental benefits and has been installed on every continent, providing significant cost savings and making our customers’ operations more efficient.


For single pressure measurements including validation and poor pressure investigation, the OSPREY can monitor pressure between 0 - 1450psi.

For multiple pressure measurements, including governor feed and MP/IP maintenance operations, the bolt-on MCA (Multi Channel Adapter) adds an additional 2 channels and can monitor pressure between 0 - 1450psi.

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.


OSPREY monitors use GPRS to report data from the field to a central HQ. SMS communication enables OSPREY monitors to be set up in the field using a cell/mobile phone. OSPREY monitors can be supplied with separate cellular and GPS antennas (most applicable to meter box installations) or a combined patch antenna where the OSPREY is installed in a metal enclosure.

This method has several advantages:

  • Massive investment in infrastructure by network providers
  • Excellent coverage in virtually all urban and semi-urban locations

  • Expanding coverage worldwide into remote/rural areas

  • Proven reliability

  • Low cost

  • 90% coverage in most countries

The OSPREY system is independent of network provider. We usually supply our monitors with a roaming SIM to ensure that the strongest network is always selected automatically. This also speeds up installation and reduces inventory (no need to have “spare” monitors fitted with alternative network SIM cards). However, we can also factory fit free-issued SIMs or supply monitors for users to fit their own SIMs.

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!

Investigate Pressure Fluctuations

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.

The OSPREY gas pressure monitoring system 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.
