Electromagnetic flowmeter installation in the front and rear distance requirements

There should be a distance of 1-3 times the pipe diameter before and after the electromagnetic flowmeter is installed.

1. Installation requirements for electromagnetic flowmeter

Electromagnetic flowmeter is a widely used flow meter, usually used to measure the flow of conductive liquids. The installation location of the instrument should meet the following requirements:

1. Keep away from the water pump inlet. Because liquid fluctuations and air mixing will occur at the inlet of the water pump, this will seriously affect the measurement accuracy of the electromagnetic flowmeter.

2. Installed on vertical pipes. Electromagnetic flowmeters can only be installed on pipes perpendicular to the flow direction. If installed on horizontal pipes, it will have a negative impact on the measurement accuracy.

3. Installed on the straight section and stable section of the pipeline. The electromagnetic flowmeter requires a stable flow state in the pipeline to measure. Therefore, a certain length of straight pipe section and stable section should be left before and after the electromagnetic flowmeter to ensure the stability of the flow rate.

4. Avoid being adjacent to pipe elbows. The installation location should avoid being adjacent to pipe elbows to avoid rotation and eddy currents in the liquid.

2. Distance between the front and back of the electromagnetic flowmeter installation position

When installing the electromagnetic flowmeter, a reasonable distance needs to be left in the front and back to avoid measurement errors. Generally speaking, there should be a distance of 1-3 times the pipe diameter before and after. That is to say, there should be a straight pipe section and a stable section before and after the electromagnetic flowmeter, and the length should be 1-3 times the pipe diameter.

In addition, it is recommended that the pipeline should be cleaned before installing a flow meter to ensure that the liquid in the pipeline is clean and the flow conditions are stable. At the same time, it should be noted that the electromagnetic flowmeter should be inspected and calibrated before installation to ensure measurement accuracy.

3. Summary

The electromagnetic flowmeter is an important instrument for measuring the flow of conductive liquid. Its installation position has a great influence on the measurement accuracy. During installation, the installation requirements should be met, and a certain length of straight pipe section and stable section should be left before and after, and the length should be 1-3 times the pipe diameter. At the same time, the electromagnetic flowmeter should be inspected and calibrated before installation to ensure its measurement accuracy. #electromagnetic flowmeter#
