  • Description

    Digital suspended solids sensor with ultrasonic cleaning, connectable to the IQ Sensor Net

    ViSolid®: Optical sensors for the in-situ use to measure suspended solids via scattered light and direct back-scattering with ultrasonic cleaning system:

    • Ultrasonic cleaning without mechanics
    • Extremely low-maintenance
    • Highly accurate factory calibration
    • High operational safety (sensor check function)

    The ultrasonic cleaning system ensures the low-maintenance and continuously reliable measuring operation of the sensors, which are therefore very suited for extreme applications, such as wastewater treatment plants.

    With higher particle concentrations, the procedures of turbidity measurement are only suitable in some cases; here, you will need special measuring techniques to determine the concentration. WTW uses two procedures, which are used depending on the suspended solids concentration: With low concentrations, a scattered light measurement is used; for higher concentrations, the direct back-scattering yields optimal results.

    Models:

    • ViSolid® 700 IQ: Digital suspended solids sensor with integrated ultrasonic cleaning (please order cable separately)
    • ViSolid® 700 IQ SW: The sea water model includes the sensor for use in special media such as desalination plants, seawater or brackish water, fish farming or high salt content. All wetted parts are made of titanium and plastic and are therefore extremely resistant to corrosion.

    Applications:

    • Wastewater
      • Sludge concentration
      • Monitoring/Controlling of sludge cycle
    • Drinking water
    • Industry
    • Surface water
    • Aquaculture
