1. Technical requirements for electromagnetic flowmeter Accuracy level The accuracy level and maximum allowable error of the flowmeter within the specified flow range should comply with the provisions of Table 1. The error of the flow meter is represented by the relative indication error of the meter. Accuracy level and maximum allowable error Accuracy level 0.2 (0.25) (0.3) 0.5 Maximum allowable error ± 0.2% (± 0.25%) Method for expressing flow meter errors; For flow meters that use a combination of relative indication error and reference error to represent errors, a unified method should also be used to represent their errors during a single calibration. The repeatability of a repetitive flow meter shall not exceed one-third of the maximum allowable absolute error specified for the corresponding and virtual accuracy levels.

JYLDE plug-in electromagnetic flowmeter is a new type of fluid flow meter developed on the basis of pipeline electromagnetic flowmeter. On the basis of the advantages of leak proof liquid retention pipeline electromagnetic flowmeter, it addresses the difficulties and high costs of installing pipeline electromagnetic flowmeter on large pipelines. Based on the principle of Nicola magnetism, it uses electromagnetic methods to measure the average flow velocity of the fluid, thereby obtaining the volumetric flow rate of the fluid. Especially with the use of pressurized opening
