Embedded electromagnetic flow meter is a new flow meter developed on the basis of pipeline electromagnetic flow meter, which not only save the advantages of pipeline electromagnetic flow meter, but also solve the difficulty of installing pipeline electromagnetic flow meter, large cost and other defects, to realize in case of stop, with pressure hole, pressure installation, pressure replacement (i.e. continuous hole, constant flow installation, constant flow replacement) and other advantages. Embedded electromagnetic flow meter has a dense structure, high measurement accuracy, and can freely change the measurement range (0.5m/s ~ 10m/s), the constant appearance size only related to the insert depth, so this type of flow meter has wide versatility, strong interchangeability and can be connected to standard secondary device or top machine to achieve long-distance transmission.
