Online water treatment turbidity meter equipped with 485 communication and 4 - 20mA output

Production Introduction

The Online Water Treatment Turbidity Meter is a cutting - edge device designed for efficient water quality monitoring. Equipped with 485 communication, it enables seamless data transfer, allowing for easy integration into various industrial control systems. The 4 - 20mA output provides accurate and stable analog signals, ensuring reliable turbidity measurement results. This meter is crucial for water treatment plants, as it helps maintain high - quality water output, safeguarding both industrial processes and public health.

Typical applications

It is used to measure the turbidity of water during the treatment of municipal sewage, industrial wastewater, and industrial slurry.
Measurement of turbidity of backwash water of filter in waterworks.
Turbidity measurement of water and sedimentation tank effluent;Industrial production process,
Water quality of circulating cooling water.
● Using scattered light and transmitted light detection technology
● Optional self-cleaning (air or water flushing) function
● Chinese/English smart menu operation
● Data recording/upload function
● Various automatic calibration functions
● Three sets of relay control switches
● High limit, low limit, hysteresis control
● 4-20MA /RS485 various signal output modes
● Password protection can be set to prevent non-staff misoperation

Measuring principle

The optical system of the turbidimeter consists of a tungsten filament lamp, a 90° detector for monitoring scattered light and a transmission light detector.The turbidimeter microprocessor calculates the signal ratio from the 90° detector and the transmission photodetector.The ratio calculation technique can correct the interference caused by chromaticity and light-absorbing substances (such as activated carbon) and compensate the influence caused by the fluctuation of light intensity, providing long-term calibration stability.The optical system of turbidimeter also requires to reduce the drifting light and improve the accuracy of test.

After the light wave sent by the transmitter on the turbidimeter sensor passes through the absorption, reflection and scattering of the measured objects in the transmission process, part of the transmitted light can illuminate the detector in the direction of 180° and part of the scattered light scatters to the detector in the direction of 90°.The light intensity received on the 180° and 90° direction detector has a certain relationship with the turbidity of the measured sewage, so the turbidity of the sewage can be calculated by measuring the intensity of transmitted light and scattered light.

Features:

1. The use of multi-beam mutual compensation technology can eliminate measurement errors caused by light window sticking, as well as temperature changes and components
Parts aging and other effects
2. LCD display, Chinese menu operation, stable performance, strong reliability, convenient operation for workers
3. The throw-in sensor is easy to install, has high accuracy, good repeatability and strong anti-interference ability
4. Support 485 communication 4-20mA analog output/support HART protocol/NB.GPRS.LORA communication (function option)
5. Complete product series, with corresponding sensors for different concentration ranges, and wide measurement range.

The sensors of the turbidity meter are mainly divided into three categories according to the different measuring ranges.

The input four-beam sensor is suitable for the measurement of high turbidity values.
Signal transmission and reception are relative, using multi-beam compensation method to calculate the current turbidity value,

It can also be used to measure the concentration of sludge, support different units, different ranges of customization.
