Electromagnetic flowmeters are now widely used. Due to their specific characteristics, understanding the basics of their installation is essential in order to make better use of them, ensure proper installation, improve efficiency, and achieve optimal results. Below are some basic guidelines for installing electromagnetic flowmeters. Proper installation of electromagnetic flowmeters: The installation orientation of electromagnetic flowmeters is generally divided into horizontal and vertical types; the appropriate orientation helps to prevent the accumulation of residues inside the measurement tube as well as within the gas flow. 1. The same potential is ensured by installing a ground reference electrode inside the sensor. The sensor and the medium must have the same potential to prevent electrode corrosion and damage, as well as to ensure measurement accuracy. If it is not possible to determine whether the medium is properly grounded, a grounding ring should be installed. If the medium flows in a lined, grounded metal pipe, it can meet the grounding requirements by being connected to the transmitter housing. Separate grounding is the same as above. 2. Regarding the support and base, if the nominal diameter is DN≥350, the transmitter must be installed on a base capable of withstanding sufficient loads; it is not permissible to use the outer frame to bear the weight of the sensor, as this will cause the frame to deform and thereby damage the internal excitation coil. At the same time, if conditions permit, it is best to avoid components such as elbows, tees, and valves when installing sensors. 3. Horizontal installation: During installation, it is necessary to ensure that the plane of the measuring electrode remains horizontal, in order to avoid short-term insulation of the electrode caused by bubbles present in the air. It is particularly important to note that the air traffic control testing function will only work correctly when the measuring device is installed with its transmitter housing in an upward and horizontal position. If the vibration is severe, it is necessary to install the transmitter and the sensor separately. 4. Vertical installation: This orientation is very suitable for pipeline systems that drain easily on their own, and it allows the use of detection electrodes for empty pipes to be omitted. 5. Ensure the inlet length of the straight sections at the export and import sides > ； 10×DN outlet length> ； The 5×DN sensors and the transmitter grounding sensor are located at the center of the pipeline to ensure measurement accuracy. Incorrect installation of electromagnetic flowmeters: 1. To prevent damage to the lining of the measurement tube due to low pressure, if the total length of the pipeline is more than five meters, a siphon tube or vent valve should be installed at the rear end of the sensor to ensure that the tube is always filled and to reduce the amount of air present. 2. Installing the pipeline at the highest point can lead to the accumulation of bubbles. 3. Installing the flow tube on the inlet side of the pump can cause suction pressures that damage the lining of the flow tube. If a piston pump, diaphragm, or reciprocator is used, a pulse throttle valve needs to be installed. 4. Install the flow meter directly in front of the opening in a downstream pipeline.
