Read the July 2002 issue of PACE (Australia’s Premier Process and
Control Trade Magazine) for independent comments on Clearguard®
and successful applications in the Alumina Refining Industry. Read
how Worsley Alumina feel about the device. Here is an extract from
the article:
"Clearguard® trial participant Andrew Crilly, Worsely Alumina
electrical/ instrument maintenance co-ordinator, says the device has
proven to be an effective tool in the accurate measurement of
process variables over a 12 month trial.

'Where we have them installed at the moment, is on our clear
filtrate tanks,' he told PACE. 'And this is probably, in our plant,
the most hostile type of environment—steam, foam, high temperatures,
very rapid flow changes, small tanks, and huge, huge volumes go
through them. We’ve got them installed there and we’re in the
process of installing them for the level on our causticiser tanks.
They look after calcium carbonate in the product, so its sort of a
lime-ish type tank. We intend to put them on all of our flash
vessels and probably some of our pressure vessels because we reckon
we’re on a winner.'"
