1. Installation method of battery powered electromagnetic flowmeter

MGG/DC battery powered flowmeter does not require external power supply, has built-in batteries and minimum requirements for upstream and downstream straight pipe sections, making the installation of the flowmeter very convenient and can be installed almost anywhere. At the same time, the shell protection level reaches IP68, which can be installed in deep wells. The choice of installation environment should be kept as far away as possible from equipment with strong electromagnetic fields. Such as large motors, large transformers, etc.

2、 The installation site should not have strong vibrations and the ambient temperature should not change significantly.

3、 A place that is convenient for installation and maintenance. Selection of installation location

1. The flow direction sign on the sensor must be consistent with the direction of the measured medium flow inside the pipeline.

2、 The installation position must ensure that the measuring tube is filled with the measured medium.

3、 Choose a location with a smaller fluid flow impulse, which should be away from the pump and local resistance components (valves, elbows, etc.). When measuring two-phase fluids, choose a location that is less likely to cause phase separation.

5、 Installation in areas with negative pressure inside the pipe should be avoided as much as possible.

6、 When the measured medium easily causes adhesion and scaling on the inner wall of the electrode and measuring tube, it is recommended that the flow velocity inside the measuring tube should not be less than 2m/s. At this point, a tapered pipe slightly smaller than the process diamete

r can be used. To clean electrodes and measuring tubes without interrupting flow in the process pipeline, sensors can be installed in parallel with cleaning ports. The straight pipe section sensor does not have downstream straight pipe section requirements, and downstream non straight pipe sections will not affect the measurement accuracy of the flowmeter. When the diameter of the upstream and downstream straight pipe sections is different from that of the sensor, a gradually expanding or reducing pipe should be installed, with a cone angle of less than 15 ° (preferably 7 ° -8 °), and then connected to the pipeline. Note: L is a multiple of the nominal diameter of the sensor, and D is the nominal diameter of the sensor. When installing the sensor horizontally, the two electrodes should be taken as horizontal positions. This way, if the medium contains bubbles or sediment, the bubbles will not adsorb near the electrodes, causing the input end of the converter to open, and the sediment will not cover the electrodes, resulting in zero drift and other phenomena. To ensure that the sensor is filled with the measured medium inside the measuring tube, the sensor position should be slightly lower than the height of the pipeline, or the sensor should have a certain positive pressure. Vertical installation is more reasonable for liquid-solid two-phase media. On the one hand, it can prevent phase separation of the measured medium, and on the other hand, it can make the lining around the inner measuring tube of the sensor wear more evenly. When installed vertically, the flow direction of the medium should be from bottom to top to ensure that the measuring pipeline inside the sensor is always filled with the measured medium. The flow
