Plug-in type electromagnetic flowmeter

The utility model belongs to the field of electromagnetic flow meters, particularly relates to an insertion type electromagnetic flow meter, and aims to solve the problems that when an insertion rod is inserted into a device in the prior art, the insertion rod needs to be connected with the device in a matched mode, the device is difficult to connect, leakage occurs at the connecting position of the device, and no monitoring device exists. The plug-in type electromagnetic flowmeter comprises a plug-in type electromagnetic flowmeter body, a connecting pipe is arranged at the bottom of the plug-in type electromagnetic flowmeter body, a base is fixedly connected to the bottom of the connecting pipe, and two monitoring boxes which are symmetrically arranged are connected to the bottom of the connecting pipe in a sliding mode. Once leakage occurs at the joint of the device, an alarm can be given to remind a worker of timely maintenance, meanwhile, two connecting flanges are arranged, the problem that the device to
