Turbidity Meter – TurbSense®

 

Online Turbidity Meters from Pi are called TurbSense® and include analysers, 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

The online TurbSense® turbidity meter can be calibrated by comparison with another measurement device (for example, a hand held turbidity meter), by placing it in a sample with known turbidity (for example, a Formazin solution or a suspension of latex spheres), or by the use of a solid secondary calibration block (please see Technical Note ‘TurbSense® Secondary Standards’ under downloads).

Calibration of TurbSense® is generally quicker and easier than with other turbidity sensors as there is no need to “zero” the sensor as through a clever use of the laws of physics (patented), there is no need for a zero.

Benefits
  • AutoClean solid state optical sensor – no moving parts
  • Single point calibration – very easy to use
  • Stable and reliable – excellent process control
  • Suitable for all potable, waste and process waters between 0 NTU and 1000 NTU
  • ‘Maintenance free’ – low cost of ownership
  • No ‘zero’ required – improved accuracy at the low end
  • Up to 1 year between calibration – very little drift
  • Up to 10 bar – for inline operation
  • 0.001 resolution
  • Automatic debubbling and bubble removal solutions – no interference from bubbles


The TurbSense® online turbidity meters are available with different controllers giving you the same great performance with different communication, display, and control options. With the TurbSense® range of online turbidity meters, you get everything that you need – and nothing that you don’t, without sacrificing the quality of the measurement.

The online turbidity meters from Pi are now in use around the world providing trouble free, easy to use solutions to a range of online turbidity monitoring and control.

Applications

Anywhere where the measurement range is 0.01-1000 NTU (approx 0-2000 mg/l, application dependent) is a suitable application for the TurbSense® online turbidity meter.

Traditional online turbidity monitoring applications where the TurbSense® is particularly suited:

  • Raw water inlet
  • Settled water turbidity
  • Final water turbidity
  • Waste water effluent turbidity
  • Fire hydrant monitoring
  • Swimming pool clarity monitoring

Models

Options for the TurbSense® include;

  • Flow cell
  • Debubbler + flow cell
  • Pressure flow cell
  • Dip mounting kit
  • Solid secondary standard


The TurbSense® is designed to mount in a flow cell. The choice of flow cell will depend upon whether you have bubbles in your sample, what sort of bubbles and whether or not you need to put the measured sample back into the process.

However, the TurbSense® can be dip mounted in an open tank. Whilst this is possible, great care must be taken to avoid bubbles and stray light. In very clean water, it will be necessary to use a sun light shield.

In addition the TurbSense® can be supplied with a solid secondary standard, for calibrating or checking the calibration.
