Installation technical requirements for insert-type electromagnetic flowmeters Insert-type electromagnetic flowmeters possess self-check and self-diagnosis functions, which facilitates maintenance. Their measurements are not affected by changes in fluid density, viscosity, temperature, pressure, or conductivity. When installing such flowmeters, it is necessary to be aware of the following installation requirements: I. Installation environment for the electromagnetic flowmeter 1. The flowmeter should be installed as far away as possible from devices that generate strong electromagnetic fields. 2. The installation site should not experience severe vibrations, and the pipes must be securely fixed; there should also be minimal fluctuations in ambient temperature. 3. The installation location should facilitate installation and maintenance. II. Selection of installation location 1. The installation location must ensure that the pipeline is always filled with the fluid being tested. The length of the straight section of the pipe for the sensor on the upstream side should be greater than 8D, while the length of the straight section on the downstream side should be at least 5D. III. Installation of the plug-in electromagnetic flowmeter sensor 1. Remove slag and burrs from the clean test tube base. 2. Install the DN50 ball valve on a base within the system, making sure that the long cavity of the ball valve faces upward; check whether the valve operates properly when opened and closed. 3. Install the compression screw valve seat kit on the ball valve, loosen the setting screw and the compression nut, and insert the sensor into the rod via the ball valve to reach the pipe being tested. Insert the sensor to a depth of 3 mm from the base; if this meets the requirements, tighten the setting screw and the compression nut. Another sign to note is a sensor whose direction is consistent with the fluid flow. IV. Welding of a base for installing LDC plug-in electromagnets and flowmeters Opening on the pipe to be measured 1. Larger than the base by 51 pipes; what about the base? The insertion depth of the opening of tube 51 into the test tube should be even on both sides, as shown in the figure ； 2. The stainless-steel electrodes of the insert-type electromagnetic flowmeter are welded to ensure that the tube axis is parallel to the flange surface afterward. V. Adjustment and Use 1. Follow the instructions provided with the plug-in electromagnetic flowmeter to connect the power supply and other necessary connections to the converter. After powering on, check the readings displayed on the instrument; ensure that the pipe being measured is filled with the working fluid and that the flow rate is zero, at which point the reading on the instrument should also be zero. 2. Fluid flow and stability within the tube: Check the instrument readings, then rotate the sensor to maximize the displayed value, lock the positioning screw, and tighten the nut.
