Title: ELECTROMAGNETIC FLOWMETER
Abstract:
[Problem] To provide an electromagnetic flowmeter having higher measurement precision than the prior art. [Solution] This electromagnetic flowmeter 10 is provided with: a resin-made flow path housing 20; a pair of porous electrodes 51, 51 embedded in the flow path housing 20 and formed from a porous conductor; a pair of electrode opposing surfaces 51A, 51A provided to the pair of porous electrodes 51, 51; a pair of electrode accommodating holes 35, 35 communicated from an outer surface of the flow path housing 20 to the pair of porous electrodes 51, 51; a pair of solid electrodes 55, 55 accommodated in the pair of electrode accommodating holes 35, 35; conductively connected porous-side connecting parts 53, 53 and solid-side connecting parts 56, 56 formed in the solid electrodes 55, 55 and the porous electrodes 51, 51 and fitted with each other; a pair of sensing electrodes 50, 50 formed by the pair of solid electrodes 55, 55 and the pair of porous electrodes 51, 51; and a seal member 36 for sealing a gap between the solid electrodes 55, 55 and the electrode accommodating holes 35, 35.
