Overview
Alderley has been providing liquid and gas measurement / metering solutions to the world's Oil, Gas and Process Industries for over 50 years with over 500 metering and proving systems reliably operating in some 40 countries worldwide.
Formerley known as Jordan Kent Metering Systems, Alderley took its new name in 2001 to adopt its new corporate image.
As the largest fully independent systems integrator in the Oil, Gas and Petrochemical Industry, we offer solutions with the best and most recent technology to meet project requirements, without bias.
Our experience in all types of high accuracy metering from fiscal/custody systems for crude oil, through dry gas and multiphase metering packages, is hard to match.
We also design and manufacture a full range of ancillary systems such as sampling and density loops, gas analysis houses and metering control panels making a complete turnkey package.
Experience & Skill
Conventional project procedures are complemented by innovative work practices including integrated Teamworking and Open Book Partnering.
In offshore and onshore production facilities, pipeline operations, terminals, refineries and power generation stations, Alderley packages set the standard.
Complete with associated equipment for control, analysis, filtration, pressure and flow regulation, all Alderley systems are designed to meet national and international standards.
First with Innovative Solutions
Unlike many metering system manufacturers, Alderley is completely independent and not tied to specific equipment vendors. This enables us to supply the most competitve and objective solution to meet the customer's requirements.
The project reference list displays how Alderley have promoted the constant advances in metering technology, improving performance and increasing value for its clients.
Ultrasonic Meters
Once considered an engineering novelty, ultrasonic flowmeters are now a common selection for metering packages. In many applications and with careful integration, these gas and liquid meters can meet and beat traditional instrument accuracies.
Loading and Unloading
The loading and unloading of road and rail tankers has always been a crucial link in bringing fuel to consumers. There is a need for special consideration of the hazardous nature of the operation - often in urban areas where safety and environmental issues are paramount. There is also a need for absolute accuracy as the value of the refined product is much greater than the crude from which it is produced.
Alderley experience brings these systems to the market, alongside the high capacity needs of marine loading and unloading packages.
Wet Gas Metering
Wet gas metering can be considered a 'special case' of the more general multiphase metering. Alderley supply both ultrasonic and venturi meters suitable for this demanding service.
Mass Metering
For some applications, coriolis mass-meters offer a technical solution for metering of difficult fluids. Oils with high viscosity and solids content can harm more traditional meters and fiscal accuracy is achievable with careful system design.
Gas Flow Conditioning
Conventional orifice flow metering systems may be enhanced by the use of proven flow conditioning elements such as perforated plate designs. Older systems too can be refurbished to improve uncertainty and to meet life of field process and equipment changes.
Integrated Solutions
To complement our design and supply of meter elements and flow computers, we have a range of upstream and downtream ancillaries. The sphere or piston provers form the backbone of conventional oil metering systems and these are supplemented by automatic sampling loops for the measurement of density, water in oil, and viscosity.
The majority of Alderley gas contracts require on-line assessment of gas quality and our packages routinely incorporate analyser or meter houses for this critical equipment. Air conditioned or freely ventilated, these incorporate chromatographs, H2S analysers, water in gas monitors, hydrocarbon dew points, automatic sampling and relative density.
Additionally, Alderley supply related systems for separation, filtration, flow and pressure control, providing a complete one-stop integrated solution.
Computer Control and Metering Systems
Most critical to the performance of any metering installation is the computer control system. To ensure proper management of this vital hardware/software interface, ASL specify and supply customer and standard panels seamlessly integrated with the metering equipment.
- User-friendly man-machine interfaces
- System mimic diagrams
- Data-trending
- Client protocol support
Sophisticated or elegantly simple, all Alderley units are line tested and exercised during factory acceptance tests for total reliability.
- Alarm tables and communicators
- Stand-alone flow computers
- Single/multi-stream flow computers
- Single/dual redundant supervisory computers
