Key Features

Measurement Principle:

Ultrasound backscattering (OLPAS Technology)


Measuring Range: 

Between: 0-20 g/L (* See below for note) 

Resolution < 0.05 % of full range (configuration dependent) (*)

Accuracy < 1 % of the measured value or 25 mg/L, whichever is greater (*)


Particle size range: Independent, nanometer - millimeter (concentration dependent)


Note: 

Sludge range 0-100 g/L is available as well, but inline measurement typically recommended due to the high viscosity of such sludges. See product OTU-SDXA.


Independence/insensitive:
Fluid colour and fluid velocity
Solids form and structure


The OLPAS measurement technology provides a cost-effective, reliable low-maintenance measurement, with low sensitivity to (bio)fouling.


Independence/insensitive
Important advantages over optical measurements:

  • Olpas sensors are not sensitive to changes in fluid colour or fluid velocity
    Olpas sensors are not sensitive to changes of solids form and structure

  • Independend to particle size 

  • No need for frequent recalibration

  • Same sensor technology available for a wide range of measurement ranges, for both inline and submerged installation.
