Differential pressure (DP) flow is still one of the most trusted and widely used technologies in industrial process systems around the world. JWF offers a wide range of DP flowmeters and primary elements to suit almost all applications. Our engineering team have access to a number of sizing programs. This allows us to evaluate your application and recommend various measuring options. See below the various product types from five different factories.
Our range of differential pressure flow meters:
Canalta's double block and bleed orifice assembly is unmatched for safety, performance and accuracy. It provides orifice plate inspection and changing without the need to shut down your process. Designed in accordance with HSE HSG253 Cat II Isolations. By partnering with Canalta we are currently the only supplier to provide the unrivalled safety of the Double Block and Bleed (DBB) orifice fitting in the UK Oil and Gas Market.
Fast and efficient removal and replacement of the orifice plate. The dual chamber meter is still a preferred option for many customers around the world.
The fitting allows for fast and efficient removal and replacement of the orifice plate after depressurisation.
We supply orifice plates, orifice flange, annular chamber, restriction (single-stage), multi-stage restriction assemblies. All orifice plates comply with AGA-3 / API 14.3 or ISO 5167-1 requirements for maximum accuracy. JWF will also carry out full orifice bore calculations based on our customers' process information.
Multi-port, self-averaging flow meter. A cost-effective solution in a number of different applications and pipe sizes.
Compact DP flow meters are all one-piece assemblies supplied fully factory configured and pressure tested. They combine all major components needed into single assemblies.
Wedgemeters measure liquids, gas and steam. Manufactured with a solid V–shaped flow restriction, the wedgemeters we supply are extremely robust.
The classical venturi flow-meter is a robust device, designed for use where low pressure–loss is required. As a consequence, energy costs can be reduced by 20-25%.
The flow nozzle is generally used for measuring the flow of steam as well as non-viscous, erosive and high velocity fluids. The nozzles are deemed budget alternatives to Venturi and Cone meters.
Stack gas flowmeter when combined with gas analyser forms a complete CEMS package for the measurement of mass flow of pollutants into the environment.
