In the deep treatment stage of wastewater treatment plants, accurate flow measurement is crucial for optimizing processes, controlling costs, and ensuring treatment effectiveness. Electromagnetic flow meter As a commonly used flow measurement instrument, it is widely used due to its high precision and high reliability. This article will detail Electromagnetic flow meter the use specifications in the deep treatment of wastewater treatment plants, with particular emphasis on the characteristics and advantages of the eletta brand.

I. Working Principle of Electromagnetic Flow Meter

Electromagnetic flow meters operate based on Faraday's law of electromagnetic induction. When a conductive liquid flows in a magnetic field, an induced electromotive force is generated on the electrodes perpendicular to the magnetic field and the flow direction, the magnitude of which is proportional to the velocity of the liquid. By measuring the induced electromotive force, the flow rate of the liquid can be calculated.

III. Installation Specifications of Electromagnetic Flow Meters

1. Installation Location Selection

It should be selected in a location with a long straight pipe section and stable water flow, avoiding installation near elbows, valves, and other local resistance components. The length of the straight pipe section before and after should meet the installation requirements of the flow meter. Generally, the front straight pipe section is not less than 5 times the pipe diameter, and the rear straight pipe section is not less than 3 times the pipe diameter.

2. Installation Direction

Ensure that the installation direction of the flow meter is consistent with the direction of liquid flow, and the arrow mark should point to the direction of fluid flow.

3. Grounding

The measurement signal of the electromagnetic flow meter is easily affected by external electromagnetic fields, so it must be well grounded. The grounding resistance should be less than the specified value to ensure the accuracy and stability of the measurement.

4. Installation Environment

Avoid installation in high-temperature, humid, and strong vibration environments. If necessary, take appropriate protective measures.

IV. Debugging and Calibration of Electromagnetic Flow Meters

1. Zero Point Calibration

After installation, zero point calibration should be performed to ensure that the flow meter outputs zero when there is no flow.

2. Full-Scale Calibration

Use a standard flow calibration device to calibrate the flow meter to its full scale to ensure the accuracy of the measurement results.

3. Parameter Setting

According to the actual measured medium and operating conditions, correctly set the parameters of the flow meter, such as pipe diameter, flow rate range, and medium conductivity.
