Sludge concentration meter

one.Sludge concentration meter application environment description

Based on the principle of infrared scattering method, Sludge concentration meter can determine the sludge concentration value regardless of chroma, without reagent and without pollution.Use the scattering or absorption properties of light to measure the concentration of sludge in water.It has high sensitivity, fast response and real-time monitoring capabilities, and is widely used in fields such as water quality monitoring and sewage treatment.

Signal output: RS485 (MODBUS-RTU).

Infrared LED light source, strong anti-interference ability.

Internal signal isolation technology, strong interference resistance.

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

Easy and simple installation, 3/4NPT pipe thread, easy to sink in or install in pipes and tanks, stable performance, long service life

IP68 waterproof standard

three.Sludge concentration meter installation and electrical connections

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 wire, and the wire sequence is defined as:

Red - power cord (12~24VDC)

Blue - Ground (GND)

Green-485B

Yellow-485A

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

Note: The color of the cable may vary slightly due to different production batches, please refer to the silk screen printing of the cable.

Four.Sludge concentration meter maintenance and care

1.Use and maintenance

The measurement window of the sensor is one of the key components to ensure the normal operation and accurate measurement of the sensor.Its cleaning requirements are critical to ensure accuracy and reliability of measurements.

1.1 Maintenance methods

1.Regular cleaning: The measurement window should be cleaned regularly to remove dirt, sediment and other impurities attached to the surface.The frequency of cleaning depends on the measurement environment, but daily or weekly cleaning is generally recommended.

2.Use mild cleaners: Use mild cleaners when cleaning, and avoid using cleaners containing abrasives or acid-base ingredients to prevent damage to the surface of the measurement window.

3.Soft cloth or sponge: During the cleaning process, a soft cloth or sponge should be used to gently wipe the surface of the measurement window to prevent scratches or wear.

4.Avoid direct contact: Avoid direct contact with the surface of the measurement window during the cleaning process to reduce fingerprint and grease contamination.

5.Rinsing: After cleaning is completed, the measurement 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 measurement window to remove water stains and ensure complete dryness.

7.Regular inspection: Regularly check the surface of the measurement window for damage or wear to maintain the normal operation of the sensor.

8.Avoid exposure to chemical substances and high-temperature environments: Avoid exposing the measurement window to harmful chemicals or high-temperature environments to prevent damage or corrosion to its surface.When the sensor is used for a long time and measurement errors occur, it can be carried out by cooperating with the instrument.Calibration and correction.When the sensor still cannot be calibrated and measured after maintaining it in the above way, it means that the sensor has failed.Please replace the sensor.

1.2 Precautions

1.The measurement window contains glass components, so avoid using sharp or hard objects to scratch the surface to prevent scratches and damage.

2.It contains sensitive optical components and precision electronic equipment.Avoid exposing the sensor to severe vibration or impact to prevent the optical parts and electronic equipment from being displaced or damaged.There is no maintenance required inside the device.

3.When not in use, an appropriate dust cover or sleeve should be used to protect the optics from dust and contaminants.
