TurbiTechw² LS Sensors
Self Cleaning Sensor for Suspended Solids and Turbidity Monitoring

The TurbiTechw² LS Sensor is designed to monitor the levels of Suspended Solids or Turbidity typically found in Final Effluent from municipal and industrial wastewater
treatment plants. It is also capable of monitoring solids in the intake to both effluent and drinking water treatment processes. The normal operating range is between
0 - 50 and 0 - 500 FTU, a version of the sensor is available that extends the range to 0-1,000 FTU.
Monitoring of these key parameters requires sensors that are reliable and accurate, the TurbiTechw² LS fills this requirement perfectly. The large optical surfaces and
sample volume ensure that the information provided by the sensor is both representative of the process and tolerant of fouling. In addition the sensor incorporates a
self cleaning mechanism that ensures that the optical surfaces are kept clean at all times, the cleaning system is designed to avoid problems with ragging and does not
smear the optical system. The cleaning system ensures that manual intervention on a routine basis is not required, the sensor should simply be checked as part of general
site housekeeping.

The TurbiTechw² LS Sensor employs infrared light at 860 nm using the 90º Light Scatter principle in accordance with ISO7027 (2000). The cleaning process is automatically initiated by the 7300w² Monitor at a user determined frequency. The cleaning process takes only 90 seconds, which means that the sensor is available for 99.5% of the time with a 5 hourly cleaning cycle.
