Across key sectors e.g. food technology, mining, and petrochemicals, product quality is verified by measuring flow properties (rheology) of liquids. Currently, these measurements are either through laboratory analysis which is highly accurate, or real-time, through in- or on-line viscometers, where low quality data compromises reliable interpretation. The OLR will deliver high quality data in real-time, to maximise the benefits achieved with real-time process control.

The OLR consists of two parallel plates, one of which oscillates axially at a fixed amplitude and variable frequency. The other measures the reaction of the process liquid to the oscillation. The process liquid is trapped between the plates during the measurement and flushed away afterwards by the process flow when the plates separate. The plates then come together again, trapping a new sample and the cycle continues.

The measured forces can be used to calculate the rheological profile of the liquid between the plates and the results can be compared with those from a standard laboratory test directly and easily. The OLR can be fitted in the main process pipe (shown schematically), or in a side-stream so that installation will be uncomplicated and low risk for the customer.
