The Water Analyser is used for continuous online monitoring of water turbidity in drinking water systems, filtration systems and direct drinking water systems. It is used there for reliable monitoring of water quality after treatment and filtration processes.
The Water Analyser operates according to the nephelometric 90° scattered light method. A tungsten lamp sends light into the water sample, which is scattered by suspended matter. A silicon sensor detects the scattered light at a 90° angle and determines the turbidity in NTU.
The Water Analyser has a measuring range of 0.001 ... 100 NTU and enables high-resolution detection of even very low turbidity values. Measurement is carried out continuously in online mode and the measured values are transmitted cyclically to an external evaluation system via the RS485 Modbus interface.
Calibration of the Water Analyser is software-assisted via the RS485/Modbus interface. First, the zero point is set using pure water (0 NTU) and then a standard solution is used for adjustment.
The Water Analyser is characterized by repeatability of ±2 % and protection rating IP65. It is designed for easy installation and low maintenance requirements. The flow rate is 300 ... 700 ml/min. The connections are 1/2 inch NPT (outlet) and 1/4 inch NPT (inlet and overflow), and the power supply is 12V DC.
This makes the device suitable for reliable and continuous monitoring of water quality in modern water treatment and process systems.
