PTU100 Turbidity Meter for Portable Water/Wastewatre Treatment for Industrial Usage
Introduction
The PTU100 Turbidity Meter utilizes optical scattered light measurement to determine the concentration of suspended particles in water. Its design adheres to recognized turbidity detection principles, ensuring consistent and accurate performance across different operating conditions. Built for online deployment, the PTU100 integrates smoothly with industrial control systems, providing continuous turbidity data without manual sampling or frequent calibration.
This turbidity meter combines a robust measurement mechanism with flexible output options and a user-friendly interface to support real-time monitoring, alarm management, and data communication. Whether used in municipal water treatment, industrial process monitoring, or environmental applications, the PTU100 measurement with professional turbidity sensors delivers dependable turbidity insights that help operators respond to process changes faster and with greater confidence.
Working principle
The PTU100 operates on the optical scattered light principle, a widely accepted method for turbidity detection in liquids. Here’s how it works:
-
A stable light source emits a beam into the water being monitored.
-
Suspended particles present in the water cause the light to scatter in various directions.
-
Photodetectors positioned at specific angles capture the scattered light intensity.
-
The meter’s electronics convert this optical signal into an electrical output that corresponds to water turbidity.
Because it focuses on scattered light rather than transmitted light alone, this method provides reliable readings even in conditions where water color, vibration, or variations in particle size might otherwise influence measurement accuracy.
