How to choose a dissatisfied tube type electromagnetic flowmeter? How to install? Electromagnetic flow meters are widely used in various fields such as sewage, fluorine chemical industry, production water, tap water industry, as well as pharmaceuticals, steel and many others. Due to its principle, it can only measure conductive liquids. When placing an order, it is not advisable to order according to the original pipe diameter. It is better to determine the instrument diameter based on your actual flow rate. Like other flow meters, electromagnetic flow meters also have requirements for straight pipelines before and after installation, with only lower requirements than other types of flow meters. Although electromagnetic flow meters have good reliability and are generally not damaged, due to their principle, the sensor electrode surface is always in contact with the liquid, and over time, the electrode surface is more susceptible to contamination. Therefore, in general, for electromagnetic flowmeters, if customers have the conditions to disassemble them, it is recommended to remove and clean the electrodes once every one to one and a half years to ensure the measurement accuracy of the entire flowmeter. How to install a dissatisfied tube type electromagnetic flowmeter? In fact, installation only needs to follow the instructions in the manual. (1) The installation location and position shall be determined as needed, but the electrode axis must be horizontal. (2) Intelligent electromagnetic flow meters must have good grounding to reduce the introduction of interference signals. There are two requirements for grounding: first, the grounding wire of the sensor and converter must be conductive with the measured medium, and second, the ground must be at zero potential. (3) To avoid signal interference, the signal line between the sensor and the converter must use a dedicated shielded wire and be separately threaded in a grounded steel pipe. The signal cable and power cable cannot be forcefully placed in the same steel pipe. (4) When the flowmeter is installed underground, an instrument well needs to be set up. (5) The unstable flow of the medium has no effect on the measured values, so there are no special requirements for the installation of flow meters on the front and rear straight pipe sections. The maintenance workload of a non full tube electromagnetic flowmeter is very small, but after running for a period of time, sewage often accumulates an adhesion layer on the inner wall of the sensor, which should be removed in a timely manner. Otherwise, when the conductivity of the adhesion layer is inconsistent with the fluid conductivity, it will cause the electrode circuit to break or short circuit, and the instrument cannot work normally. Therefore, for the measurement of industrial wastewater, it is best to ensure that the fluid flow rate is above 3-4 m/s when selecting flow meters, which can to some extent play a role in self-cleaning the pipeline and preventing the deposition of adhesion layers. From the appearance, the non full tube electromagnetic flowmeter is not much different from the ordinary electromagnetic flowmeter. It also has the advantages of being unaffected by fluid parameters, having no movable parts, no flow blocking components, minimal pressure loss, no measurement hysteresis, linear output, and wide range. The measurement channel of non full tube electromagnetic flowmeter is a smooth straight pipe without blockage, ma
