How it works
During turbidity measurement, when a light beam directed into the process medium encounters opaque particles, such as suspended solids, the beam changes its original propagation direction. This phenomenon is known as light scattering.
Incident light is scattered in multiple directions. Scattered light at two angles is particularly important for turbidity measurement: 90° scattered light is mainly used for turbidity measurement in drinking water, while 135° scattered light is used for measurements at higher particle concentrations.
At low concentrations of suspended solids in the process medium, most of the light is scattered at 90°, with relatively little light scattered at 135°. As the concentration of suspended solids increases, the ratio changes: the intensity of 135° scattered light increases, while the intensity of 90° scattered light decreases.
Key features
• Laboratory-grade measurement: Highly accurate and reliable water quality monitoring, even at the lowest turbidity levels.
• Turbidity measurement without product loss: Hygienic inline measurement preserves every drop of water within the process.
• Unattended operation: Intelligent design and practical accessories enable advanced self-cleaning capabilities and minimize maintenance requirements.
• Smart verification and calibration: Safe, liquid-free verification and calibration without the use of Formazin.
• High flexibility and easy handling: One sensor for a wide range of measuring points and installation environments, including inline and immersion installations.
• Improved process control: Sensor response time can be individually adapted to the application.
• Fast commissioning: Factory calibration and Memosens technology enable plug-and-play integration into the process.
