[0017] figure 1 It is an external perspective view of the measurement device of the first embodiment. Such as figure 1 As shown, the measurement device is used to measure the flow rate of a fluid as an object to be measured, and is composed of an electromagnetic flowmeter 100 and a control unit 400 . The electromagnetic flowmeter 100 is provided with: a measuring tube 1 through which a fluid as an object to be measured flows, and a pair of electrode members 2 facing the peripheral wall of the measuring tube 1 (see figure 2 ). In addition, flanges 1a and 1b for connecting to piping not shown are provided at both ends of the measuring tube 1 . The control unit 400 is integrally formed with the electromagnetic flowmeter 100 , and is usually installed above the measuring tube 1 of the electromagnetic flowmeter 100 .

Abstract

The invention provides an electronmagnetic flowmeter and a determinator, which can ensure tightness. Moreover, the sealing component is not damaged by squeezing, and can not be squeezed out between the electrode component and the determinator. The electromagnetic flowmeter comprises a determinator (1), an electrode component (2), spring (7) and a gasket (3). The determinator is provided with a tubular peripheral wall with a through-hole (10), and the inner part of the peripheral wall has fuild, and the inner peripheral surface of the through-hole is provided with an inclined plane (10a). The electrode component is inserted in the through-hole, and has an inclined plane (1b), which is opposited to the inclined plane (10a), and the diameter is reduced along the inner part of the periphearl surface to the outside; an a protruding part (20), which is protruded from the inclined surface in a ring shape, and is against the inclined surface, and a gap is provided between the inclined surfaces. The spring (7) pushes the electrode component to the outside from the inner part of the peripheral surface. The gasket is a ring shaped component, and is clamped in the gap between inclined surfaces in a pressed state.

Description

[0001] This application is based on Japanese Patent Application No. 2012-012908 filed on January 25, 2012 and enjoys the priority of this earlier application. This application incorporates the entire content of this earlier application by referring to it. technical field [0002] Embodiments of the present invention relate to an electromagnetic flowmeter and a measurement device. Background technique [0003] Conventionally, as a device for measuring the state of an object to be measured as a physical quantity, for example, an electromagnetic flowmeter for measuring the flow rate of a liquid and a thermometer for measuring the temperature of a liquid are known. In this electromagnetic flowmeter, a magnetic field is generated in a measuring tube by passing a current through a coil. Then, the flow rate is measured by detecting an electromotive force generated in a direction perpendicular to the magnetic field in proportion to the flow velocity of the liquid flowing in the mea...
