- Interface and sludge level detection independent of density
- Indicates the current sludge level
- Programming on site via dialog mode orper RS232 via PC software
- No readjustment required
- Sensor-integrated fully automatic cleaningequipment for extreme requirements
NivuScope 2 makes your tanks and basins transparent.
The Measurement Method
The sensor emits directed high frequency impulses into the liquid.
For that purpose, the sensor must be immersedinto the liquid to be measured for a few centimetres.
However it necessarily shall be positioned always above the topmost interface to be measured. Solid particles or sludge contained in the liquid will reflect the sound waves back to the sensor, which subsequently converts the acoustic signals into electric signals.
The intensity of the received signal depending on the ultrasonic transit time is evaluated and will be indicated as a graph on the display.
The NivuScope 2 is particularly suitable for use in:
Wastewater treatment plants
Primary and secondary clarification tanks, thickeners
Fresh water treatment facilities
Sludge sedimentation tanks
Industry/Chemical
Sedimentation monitoring
