Non-contact free-fall concept

Water passes through the AquaScat without touching the optics:

» No window fouling. Hence, the measured values are not falsified and there is no drift.

» Very Low to very high turbidity values can be measured with no contamination of the optics

» Dissolved metals like iron or manganese do not contaminate the optics

» Extremely low maintenance is the result

Measuring light passes through the entire sample beam:

» There is no selection of the sample at the surface. The entire water beam is measured and hence, the result is representative.

Re-calibration with secondarystandard (High stability optical glass)

» Precise re-calibration is possible without the use of Formazine

» Allows a stable measurement over a long time period

» Allows a fully automatic operation » Purchase and storage of Formazine

is not needed

WTMA: Automatic calibration check

WTM and HT: Manual calibration check

Low levels of stray light

The design of the AquaScat in combination with

high quality optical components minimizes the

quantity of stray light inside the instrument:

Control Unit

The control unit of all AquaScat is a colour touch screen:

» Values, graphs, alarm and status messages can be selected by the operator.

» An internal data logger allows the recall of measured data for the last 32 days

» Password protection avoids unauthorized access

» Various means of communication including an integrated web server

Cost of ownership

In addition to its daily dependability, the product design was focused on long useable life and low maintenance costs:

» The maintenance work is very low» The cost for consumables during 10

years of operation are at AUD 150

Turbidity measurement application

» The installation is simple» An optional de-aeration system can be

installed if required.» 2 Analogue outputs can transfer two

measuring ranges to the PLC
