Flowmeter aids accuracy level
July 1st 2007

FLOWMETER AIDS Colcrete Eurodrill has standardised on installing Krohne's Optiflux 5300 electromagnetic flowmeter in the specialist pumping stations it manufactures.

The company fits the flowmeters in equipment used to inject grout (or cement) underground to fill the annulus between tunnel ring segments and the ground around them or to construct grout curtains.

The flowmeters help to ensure and validate that a precise ratio of grout and additive are combined so that the mixture will gel correctly.

As well as monitoring the flow of grout and additives, the flowmeters provide an outfeed to a datalogger which records detailed information for future use.

Colcrete Eurodrill chose to standardise on the Optiflux 5300 because its ceramic lining provides high levels of resistance to wear, particularly in high solid applications. The reliable performance of the instrument has been such that the company now has more than 100 Optiflux flowmeters operating around the world.

The device is an all-inone electromagnetic flowmeter that incorporates three levels of diagnostics and is said to set new industry standards of metrological performance and accuracy.
