PURPOSE:To perform repair or the like of a vortex detecting part without removing the flowmeter from a pipe, by providing valve mechanisms which open and close pressure conducting paths, respectively. CONSTITUTION:When a magnetic disk 5 or the like is repaired or replaced, at first, the valve mechanisms 10 and 11 of the pressure conducting paths 3a and 3b are closed. Then a sensor housing 4 is disassembled at a divided part 4a, and a detecting part A is opened so that it is exposed to the outside. Since a fluid flow path to the detecting part A from a main body 1 of the flowmeter is already shut off at this time, the fluid to be measured does not flow to the outside. Therefore, the magnetic disk 5 or the like can be readily taken out of the opening of the detecting part A, and washed or repaired in the state the main body 1 of the flowmeter is attached to the pipe. |
