Turbidity Meter – TurbSense®

SoliSense® Inline Tip
Online Turbidity Meter – TurbSense®

Online Turbidity Meters from Pi are called TurbSense® and include analyzers, controllers and monitors which determine true online turbidity and/or suspended solids in water, using a nephelometric measurement of scattered light in accordance with ISO 7027. The TurbSense® sensor uses LED optical technology to provide an extremely stable, accurate, low maintenance sensor.

The TurbSense® online turbidity meter is a breakthrough in measurement technologies in that it automatically varies the light output so that the turbidity can be measured independently of background light and electronic drift.

Ranging from 0.01 NTU to 1000 NTU with a resolution in the 0-10 NTU range of 0.001, the TurbSense® online turbidity meter provides:

  • Excellent resolution
  • Single point calibration
  • The simplicity of a probe
  • Great value for money
  • Long term reliability
  • Autoclean so very low maintenance
Turbidity Monitor Flow Cell
Debubbling Flow Cell – TurbSense®

Each probe is equipped with a light source, a side detector for the measurement of scattered light from the sample and a reference detector for monitoring the light output. The light source is a long-life IR LED emitter. This configuration allows accurate and reliable measurements of online turbidity and suspended solids to be made. Reliable calibration can be carried out using a single calibration with no need for a ‘zero’.

The probes are constructed of stainless steel and sapphire so can withstand demanding operating environments. An Autoclean system can be included to keep the optical surfaces clean, thereby reducing maintenance to a potential ‘maintenance free’.

The TurbSense® online turbidity meter is suitable for dip monitoring and mounting in a debubbling flow cell.

The operating principle of the online turbidity meter is subject to a patent application and is unique in the way it handles the data it receives in order to calculate a zero, to calibrate and to derive the NTU (FNU) value from the readings.
