Sludge concentration meter

one.Sludge concentration meter application environment description

Sludge concentration meter is suitable for measuring the concentration of suspended solids (sludge) in municipal sewage or industry.The scattering or absorption properties of light are used to measure the concentration of sludge in water.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 has strong interference.

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

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

IP68 waterproof standard

three.Sludge concentration meter installation and electrical connection

1.Sludge concentration meter installation

Installation distance requirements: Keep it 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 line sequence is defined:

Red - Power cord (12~24VDC)

Blue-ground (GND)

Green-485B

Yellow-485A

Before powering on, carefully check the wiring sequence to avoid unnecessary losses caused by wiring errors.

Note: The color of the cable may vary slightly depending on the production batch.The specific color of the cable is subject to the silk screen printing.

Four.Sludge concentration meter maintenance and maintenance

1.Use and maintain

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

1.1 Maintenance method

1.Regular cleaning: The measurement 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 daily or weekly cleaning is generally recommended.

2.Use gentle detergent: When cleaning, you should choose gentle detergents 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, use a soft cloth or sponge to gently wipe the surface of the measurement window to prevent scratches or wear.

4.Avoid direct contact: Avoid touching the measuring window surface directly during cleaning to reduce fingerprint and grease contamination.

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

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

7.Regular inspection: Regularly check the surface of the measurement window for damage or wear to keep the sensor running normally.

8.Avoid exposure to chemical substances and high temperature environments: Avoid exposing the measurement window to harmful chemical substances or high temperature environments to prevent damage to its surface or corrosion.When the sensor is used for a long time, calibration and calibration can be performed by matching the instrument.When the sensor is still unable to be calibrated and measured, it means that the sensor has failed.Please replace the sensor.

1.2 Things to note

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

2.It contains sensitive optical components and precision electronic equipment inside to avoid exposing the sensor to violent vibration or impact, so as to prevent the displacement or damage of the optical parts and electronic equipment.No maintenance is required inside the equipment.

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