In the production process of chemical fiber plants, accurate measurement of polyester melt flow is crucial for ensuring product quality and optimizing production processes. Electromagnetic flow meter As a commonly used flow measurement instrument, it plays an important role in the measurement of polyester melt flow. This article will detail Electromagnetic flow meter the use techniques in polyester melt flow measurement in chemical fiber plants, and elaborate on the characteristics of the eletta brand.

I. Working Principle of Electromagnetic Flow Meter

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

II. Characteristics of Polyester Melt in Chemical Fiber Plants and Requirements for Flow Measurement

Polyester melt has characteristics such as high temperature, high viscosity, and corrosiveness, which put high demands on flow measurement instruments. First, the instrument must be able to withstand high-temperature environments; typically, the temperature of polyester melt is around 280℃. Second, due to the high viscosity of the melt, the instrument needs good wear resistance and anti-blocking ability. In addition, the instrument is required to have high accuracy, stability, and reliability to meet the control and quality inspection needs of the production process.

It should be installed in a place with a long straight pipe section. The length of the straight pipe sections before and after should meet the requirements of the instrument to ensure smooth fluid flow and reduce vortices and interference.

2. Correct Installation Direction

The installation direction of the electromagnetic flow meter should be consistent with the flow direction of the fluid to ensure measurement accuracy.

3. Installation Height and Support

Considering the convenience of maintenance and inspection, the installation height should be moderate, and stable support should be provided to prevent pipe vibration from affecting the measurement.

4. Grounding Treatment

In order to reduce electromagnetic interference, the grounding of the electromagnetic flow meter must be good to ensure stable signal transmission.

V. Debugging and Calibration of Electromagnetic Flow Meters

1. Zero Point Calibration

After installation, zero point calibration is very important. Ensure that when there is no fluid flow in the pipe, the instrument displays zero.

2. Full-Scale Calibration

Use a standard flow calibration device to calibrate the electromagnetic flow meter to ensure the accuracy of the measurement range.

3. Parameter Setting

According to the actual process parameters and fluid characteristics, correctly set the parameters of the flow meter, such as pipe diameter, medium type, and temperature.

VI. Precautions in Operation and Maintenance

1. Regular Inspection

Regularly check the working status of the electromagnetic flow meter, including the sensor, converter, wiring, etc., and promptly identify and address potential problems.

2. Cleaning and Maintenance

Regularly clean the sensor and pipes of the flow meter to prevent the accumulation of dirt and sediment from affecting the measurement accuracy.

3. Fault Diagnosis and Handling

When measurement abnormalities occur, fault diagnosis should be carried out promptly to analyze the possible causes, such as electromagnetic interference, pipe blockage, sensor damage, etc., and take corresponding remedial measures.

4. Spare Parts Management

Reserve necessary spare parts so that they can be replaced promptly when the instrument malfunctions, reducing downtime.
