High Accuracy Fast Response Lazer Water Tubidity Sensor For Secondary Water Supply

High Accuracy Fast Response Lazer Water Tubidity Sensor For Secondary Water Supply

For low-range turbidity measurement, the selection of turbidity light source is very critical.

Traditional light sources are generally infrared LED emitters and tungsten halogen circulating incandescent lamps; infrared LED emitters have low brightness, low light efficiency, poor directionality, and large errors at specific wavelengths; tungsten halogen lamps The lamp has poor shock resistance, short life, and high calorific value. It can easily heat up the sample, stimulate the liquid sample to precipitate bubbles, and interfere with the measurement. Based on the above defects, the above two methods can only be used for general requirements measurement, but the advantages are low implementation cost and relatively mature technology.

Laser light source is considered to be the most ideal light source substitute that can meet the needs of higher detection requirements. Laser is a light source generated by stimulated radiation. It has good directionality, single beam, and concentrated frequency. It mainly produces light of a single wavelength, and the light error of a specific wavelength is very small. These characteristics are particularly important when used in low concentration measurement environments.

The flow-through scattering turbidity method requires a container for the measured sample to circulate. The main purpose of the container is to isolate the interference of external light on the measurement. The other main purpose is to stabilize the flow rate and precipitate and release bubbles in the water, which is called scattering. Turbidity flow cell. The turbidity flow cell can eliminate the interference of bubbles on the measurement to the greatest extent.

Flow-through scattering turbidity detection requires a certain amount of sample. Miniaturization is the key to reducing sample consumption. The flow cell design of Daruifuno greatly reduces the dependence on sample volume, only 100ml/min is required. flow, stable measurement can be achieved.

Daruifuno turbidity flow cell, in order to prevent the settlement of suspended solids caused by low-speed flow, a stream-type sample track was invented. The sample track uses certain regular bottom ridges to form local turbulence and slow-flow effects. On the one hand, it can be used The turbulence and slow flow effects uniformly stir the sample and push the suspended solids to prevent settlement. On the other hand, the surface area of the runway is expanded, which is beneficial to the release of pressure on the sample and the precipitation of bubbles. Obtaining a stable sample is an important factor in achieving accurate measurements.

Daruifuno's OLTU series digital turbidity sensors are developed and produced based on digital requirements. They use a laser scattering photometer to measure turbidity.

OLTU is specially designed for low-range turbidity measurement. It has a small flow-through installation structure and a small sampling volume, which is conducive to integration.

The laser emitted by the OLTU series online turbidity sensor is injected into the sample and measures the scattered light generated by the suspended particles in the sample. Scattered light at 90° to the incident beam is detected by a transmitted light detector.

The intensity of scattered light is directly proportional to the suspended particulate matter in the water sample. If the sample contains tiny suspended particles, then very little scattered light will be detected by the laser turbidimeter's detector, so the turbidity value will be lower. On the contrary, large suspended particles will form stronger scattered light, resulting in higher turbidity values.

The sensor obtains the turbidity value of the water sample by calculating the relationship between the 90-degree scattered light and the incident light beam.

It aims to monitor the turbidity level of drinking water in real time to ensure safe and qualified water quality. The following are the main application environments for this sensor:

Drinking water production line: In the drinking water production line, the sensor can be installed at key positions in the process to monitor the turbidity of water samples in real time. This helps detect anomalies in the treatment process and if treatment needs to be adjusted to keep the water quality stable.

Waterworks: Waterworks are responsible for treating and supplying tap water to urban residents. The drinking water flow-through low turbidity laser sensor can be installed at the water inlet and outlet of the water plant to continuously monitor the turbidity changes of the raw water and the treated tap water. In this way, potential water quality problems can be detected in time, and measures can be taken to ensure that the drinking water supplied meets safe standards.

Water treatment facilities: In other types of water treatment facilities, such as sewage treatment plants, industrial wastewater treatment plants, etc., the sensor can also be applied. It monitors water quality changes during treatment and helps operators adjust and optimize treatment methods to meet treatment requirements and reduce environmental impact.

Drinking water quality monitoring station: Drinking water flow-through low-turbidity laser sensors can be deployed in drinking water quality monitoring stations in cities or communities for real-time monitoring of water quality in water supply systems.
