Water flow meter manufacturer Pulsar Process Measurement has helped UK utility Drw Cymru Welsh Water save £1.5 million using its Flow Pulse product to monitor flow rates within critical sewage pumping stations (SPS) under normal and storm conditions.

Developed in co-operation with Welsh Water, Flow Pulse uses advanced digital refracted spread spectrum analysis (RSSA) within a clamp-on, non-invasive flow monitor, reports Environmental Technology.

Welsh Water was looking to monitor around 250 points across its SPS network.

The utility believed magflow meters were prohibitively expensive to implement and opted for Pulsar’s Flow Pulse, which can be mounted with a screwdriver.

Welsh Water estimates that it will see savings compared to magflow meters of £1.5 million over the full project, an average of £6,000 per installation.

Flow Pulse is being used by other water companies, with over 1,000 now having been installed in the UK.

Low power flow meter 

Meanwhile, another UK flow meter maker Titan Enterprises has launched a new version of its 800 series turbine flow meter for companies that wish to monitor flow without installing a wiring loom or in remote situations.

Designed to operate on 3V batteries, the new flow meter has a very low power consumption making it suitable for battery-powered equipment.

The 800 series turbine flow meter is designed for five flow ranges from 0.05 to 15 litres per minute.

It’s non-metallic wetted components make it suitable for metering a wide range of fluids from -25°C to +85°C.

At the heart of the 800 series flow meter is a precision turbine that rotates on sapphire bearings and contains chemically resistant ceramic magnets that are detected through the chamber wall by a bespoke sensor system.

The output is a stream of 3V pulses that are readily interfaced with most electronic display or recording devices.
