Despite great strides in technology, the fluid-mechanics of the open channel is fraught with technical difficulties.  Surface waves, hydraulic jumps and hidden vorticity confound the smartest technologies.

However, the basic weir and flume methods are simple, utterly reliable and robust and offer the lowest levels of measurement uncertainty.

Design and Innovation

In recent years, the procurement of equipment has been rationalised to the point that only 'the conventional' is recognised.  Innovation struggles in such an environment.  This has the effect of isolating innovative companies, from the supply chain.

By manufacturing and supplying a range of innovative products developed in the UK by Hymetrics, FM can offer next generation products.  Today, high performance gauging structures developed for industrial application and later in 2011, the RotoChute flow diverter for precise control of flow at inlet works and drainage systems.

Manufacture & Supply

FlowMarque 'FMcert' hydrometric structures are designed for industrial use and are precisely manufactured in durable and corrosion resistant high-chromium stainless steels.

• Seamless automation from the calibration rig to the manufactured product.
• Proprietary software application that allows accurate production of hydrometric structures in a controlled environment traceable back to rigorous structure calibration.
• Products are scalable to enable them to provide measurement over a wide range of flow conditions.

Calibration Expertise

Our 'FMcert' Certificates of Performance are derived from thousands of traceable measurements, which through automated calibration, enables discharge uncertainties to be accurately determined.

We support our technologies with design consultancy and provide support to most of the leading names working in the UK.  Our working methods are available to any client seeking guidance, or more detailed analysis.
