Our first metering system was produced in 1959 and since then Alderley has led the way in hydrocarbon metering solutions, achieving significant milestones along the way. To complement the major systems, Alderley also design and manufacture a range of ancillary systems, such as sampling/density loops...
All fiscal or custody metering systems require solid and incorruptible flow computer technology. Alderley's experience in this sector is considerable, beginning as it did with its connections to Kent Instruments.
Alderley's experience of conventional metering systems spans 45 years. Just some of the many projects we have built are shown here.
Alderley has been supplying metering systems for over 45 years has grown into a world leader in the supply of systems to meter gaseous hydrocarbon products. Our experience in providing high accuracy metering systems coupled with our expertise in the latest technological developments makes us the leading choice for your metering requirement. Our experience includes the design and manufacture of gas ultrasonic metering systems using 36” meters, as well as systems operating at 10,000psig.
There are simply too many of the company's "firsts" to be shown. Here are some examples.
Alderley has been supplying metering systems for over 45 years and has grown into a world leader in the supply of systems to meter liquid hydrocarbon products. Our experience in providing high accuracy metering systems coupled with our expertise in the latest technological developments makes us the leading choice for your metering requirement.
The skills learnt in the design and manufacture of fiscal or custody metering packages are put to good use in the construction of loading and unloading skids. These systems can have harsh treatment in operation, and special consideration is given to ease of operation and accessibility.
For some applications, coriolis mass-meters offer a technical solution for metering of difficult fliuds. Oils with high viscosity and solids content can harm more traditional meters and fiscal accuracy can be achieved with careful system design. Coriolis or mass metering has come a long way since Alderley helped with its introduction to the North Sea in 1993.
Most larger fiscal or custody packages require some level of quality analysis. Alderley's turnkey solutions supply all these most necessary ancillaries.
Alderley have been amongst the first to apply ultrasonic flow metering techniques to gas and oil in custody and allocation systems. Our earliest ultrasonic gas systems date from 1995, and the liquid ultrasonic from 1997.
Our scope includes the design and manufacture of produced water treatment systems incorporating one or more stages capable of reducing oil-in-water levels to less than 0.5ppm; and water injection systems for enhanced oil recovery. A wide range of process units can be supplied to suit the individual ...

Over the past 20 years, the hydrocyclone has become the primary treatment mechanism for free oil removal from oilfield produced water. Rising levels of environmental concern however have led to the need to meet increasingly arduous discharge limits, such that new complementary technologies must be used to supplement the hydrocyclone's performance and reduce not only the free oil levels in discharge waters but also engage the problem of dissolved hydrocarbon content.
Alderley have developed the AP-20 liquid-liquid hydrocyclone to ensure we can provide the most efficient solutions to meet the constantly reducing produced water discharge limits. The AP-20 is capable of reducing outlet levels of oil-in-water to less than half that of other hydrocyclone designs.
Where the ultimate goal is zero discharge, we have a range of products to meet the requirements. Alderley’s tertiary treatment range includes media filters, the COP System (coalescing filter) and absorption filters to reduce the oil levels in the produced water to below the required limits. Alderley’s H2S strippers provide removal of the highly corrosive hydrogen sulphide gas that can cause stress cracking, or more usually prevent H2S being discharged overboard into the environment.
A solids wash cyclone can be used to cleanse solids prior to disposal, recycling the material from the accumulator vessel as required to attain the desired level of cleanliness. A guaranteed level of oil entrainment on the solids can thus be maintained. Alderley’s solids treatment system design is such that these systems can be incorporated as necessary in the overall produced water treatment package.
In addition to our Produced Water Treatment capability, Alderley design and integrate complete Water Injection Systems for enhanced oil recovery, incorporating some of the Best Available Technology for each process item.
Specialised Management Services (SMS) strengthens the quality range of products and services that Alderley can offer, incorporating further knowledge and experience with wellhead control systems, and providing extended customer care solutions (consultancy, commissioning, system maintenance, servicin...
