Online Turbidity Monitor

I. Product Overview

Depending on the suspended solids or sludge content to be measured, turbidity instruments are divided into low-range turbidity meters, high-range turbidity meters and sludge concentration meters. The turbidity analyzer is an online instrument designed to measure the turbidity of municipal sewage and industrial wastewater. It works on the principle that the light transmittance is proportional to the turbidity of the water under test and provides continuous and accurate results. Turbidity is a scattering phenomenon produced by colloidal particles suspended in water, mainly caused by mud, organic matter and micro-organisms. It is widely used in tap water, sewage, petroleum, chemical, metallurgy, power, food, pharmaceutical, papermaking, agricultural irrigation, domestic water and mining applications.

II. Key Features

1. Multi-beam mutual compensation technology eliminates measurement errors caused by fouling of the optical window as well as the influence of temperature changes and component ageing.

2. LCD display with a Chinese menu; stable performance, high reliability and easy operation.

3. Immersion sensor: easy to install, high accuracy, good repeatability and strong anti-interference capability.

4. RS485 communication, 4–20 mA analogue output, HART protocol and NB / GPRS / LORA communication (optional).

5. The immersion single-beam sensor is suitable for turbidity up to 1,000 NTU; the emitter and receiver are arranged at a 90° angle and the turbidity is calculated from the scattered light produced by colloidal particles suspended in the water.

6. The immersion four-beam sensor is suitable for high turbidity; the emitter and receiver face each other and a multi-beam compensation method is used to calculate the current turbidity value. It can also measure sludge concentration, and different units and ranges can be customised.

7. The ultrasonic sensor uses the proportional relationship between concentration and acoustic energy attenuation to measure even higher concentrations of slurry and ore pulp, with a range of more than 200 g/L.
