Micronics flow meter delivers 10 years of reliable operation
The reliability of the Micronics non-invasive method of ultrasonic water-flow measurement has been demonstrated for 10 years at a pig-processing factory. It was that long ago that Hendy & Sons of Taunton, a long-established company of drainage and water engineers was asked to provide a control system for a submersible pump as part of abstraction agreement for the factory. A condition of the agreement was for 2 l/s of the abstractions from an underground spring to be fed to the local brook.
The initial system used a UF2000 time-of-flight fixed-flow meter. Its flow-rate signal is fed to an inverter, which modulates the speed of the pump to maintain a constant flow-rate return from the spring to the brook.
Alan Hendy of Hendy & Sons, says, ‘The system, including the Micronics flow meter, has operated reliably for 10 years, and the new owners of the plant are now considering the use of further UF2000s as part of their investigation into a new extended water-abstraction system, which will optimise the usage and costs associated with water from a mains supply, on-site borehole and the underground spring.’
