。[Claims for Utility Model Registration] The main body includes a conduit, a pair of electrodes disposed within the conduit in a direction perpendicular to the tube axis, and an excitation coil for applying a magnetic field in a direction perpendicular to the tube axis and electrode direction. In an electromagnetic flowmeter that derives the flow rate of liquid flowing in the conduit by a voltage signal induced between the pair of electrodes, an ultrasonic probe and the ultrasonic probe are provided outside the conduit. and a discrimination means for discriminating whether the level of a received signal obtained by the ultrasonic wave transmitted from the tentacle propagating in the pipe is at a predetermined level, and the output of the discrimination means determines whether or not the ultrasonic wave is transmitted through the pipe. An electromagnetic flowmeter characterized by detecting whether or not a fluid is full.
