Sludge concentration meter

1.Application environment description of sludge concentration meter

Sludge concentration meter is an online analyzer designed to measure the concentration of suspended sludge in sewage or industrial wastewater treatment.The concentration of sludge in water is measured by using the scattering or absorption characteristics of light. It has high sensitivity, fast response and real-time monitoring capabilities, and is widely used in water quality monitoring and sewage treatment.

Signal output: RS485 (MODBUS-RTU).

Infrared LED light source, strong anti-interference ability.

Internal signal isolation technology, strong anti-interference.

Good reproducibility, thermal stability, low drift, small size, fast response

Easy and simple installation, 3/4NPT pipe thread, convenient for submerged installation or installation in pipes and tanks, stable performance and long service life

IP68 waterproof standard

2. Technical performance and specifications of Sludge concentration meter

1. Technical parameters

2. Sludge concentration meter dimensions

The sensor connector is an M12 aviation plug connector with 5 pins.

3. Sludge concentration meter installation and electrical connection

1.Sludge concentration meter installation

Installation distance requirements: keep more than 5cm from the side wall and more than 10cm from the bottom.

2. Electrical installation

The cable is a 4-core shielded cable, and the line sequence definition is:

Red - power line (12~24VDC)

Blue - Ground (GND)

Green-485B

Yellow-485A

The wiring sequence should be carefully checked before powering on to avoid unnecessary losses due to wiring errors.

Note: The cable color may vary slightly due to different production batches. Please refer to the cable silk screen for details.

4. Sludge concentration meter maintenance and care

1. Use and maintenance

The sensor's measurement window is one of the key components to ensure the sensor works properly and measures accurately. Its cleaning requirements are critical to ensure the accuracy and reliability of the measurement.

1.1 Maintenance methods

1. Regular cleaning: The measuring window should be cleaned regularly to remove dirt, sediment and other impurities attached to the surface. The cleaning frequency depends on the measurement environment, but it is generally recommended to clean it every day or every week.

2. Use mild detergent: When cleaning, you should choose a mild detergent and avoid using detergents containing abrasives or acid-base components to prevent damage to the surface of the measuring window.

3. Soft cloth or sponge: During cleaning, use a soft cloth or sponge to gently wipe the surface of the measuring window to prevent scratches or abrasions.

4. Avoid direct contact: Avoid touching the measuring window surface directly with your hands during cleaning to reduce contamination from fingerprints and grease.

5. Rinse: After cleaning, the measuring window should be rinsed thoroughly with clean water to ensure that residual detergent and dirt are removed.

6. Drying: After cleaning, use a dry soft cloth to gently wipe the surface of the measuring window to remove water stains and ensure complete drying.

7. Regular inspection: Regularly check whether the measuring window surface is damaged or worn to maintain the normal operation of the sensor.

8. Avoid exposure to chemicals and high temperatures: Avoid exposing the measuring window to harmful chemicals or high temperatures to prevent damage or corrosion to its surface. When the sensor has been used for a long time and measurement errors occur, it can be calibrated by cooperating with the instrument. If the sensor cannot be calibrated and measured after the above maintenance and care, it means that the sensor has failed. Please replace the sensor.

1.2 Notes

1. The measuring window contains glass components, so avoid scratching the surface with sharp or hard objects to prevent scratches and damage.

2. The sensor contains sensitive optical components and precision electronic devices. Avoid exposing it to severe vibration or impact to prevent displacement or damage to the optical parts and electronic devices. No maintenance is required inside the device.

3. When not in use, appropriate dust covers or sleeves should be used to protect the optical parts from dust and contaminants.
