Magnetic Flowmeter In The Installation Of What Need To Pay Attention To The Problem

magnetic flowmeter installation location selection is critical. Should be avoided in the installation of strong vibration, electromagnetic interference or temperature changes in the place, these factors may be on the normal operation of the flowmeter interference. At the same time, should ensure that the installation pipeline is full of the measured liquid, to avoid the mixing of gas or air bubbles, because this will affect the measurement accuracy.

The sensor of the electromagnetic flowmeter should be installed horizontally or vertically with the axis of the pipeline, avoiding inclined installation. When installed horizontally, the sensor should be installed at the bottom of the pipeline to exclude any sediment that may exist in the pipeline. When installed vertically, attention needs to be paid to the flow direction of the liquid to ensure that the sensor is installed on the upstream side of the liquid.

In the installation process, should also pay attention to the electromagnetic flowmeter and pipeline connection. General flange connection or threaded connection, whichever way, should ensure that the connection is well sealed to avoid leakage. At the same time, the caliber of the connecting pipe should be consistent with the caliber of the flowmeter to ensure the accuracy of the measurement.

When installing the electromagnetic flow meter, you also need to pay special attention to the grounding problem. The working principle of electromagnetic flowmeter is based on electromagnetic induction, so poor grounding will lead to increased measurement error or even damage to the instrument. In the installation process, should ensure that the flow meter shell, sensor and piping system is well grounded, grounding resistance should not be greater than 10 ohms.

The installation of electromagnetic flowmeter is a process that requires rigorous and careful. In the installation process, special attention should be paid to the selection of the installation location, the sensor and the pipeline connection, grounding issues, as well as debugging and calibration and other details. Only by ensuring that the installation is correct, can we ensure that the electromagnetic flowmeter can operate accurately and stably, and provide reliable data support for industrial automation measurement.
