Claims

[Scope of utility model registration request]

A rotating body that rotates according to the flow of the fluid to be measured, a fixed member placed opposite to this rotating body, and the polarity of each magnetic pole on the side facing this fixed member is opposite to the polarity of the adjacent magnetic pole. , and an even number of permanent magnets fixed to the rotating body at approximately equal intervals in the rotational direction of the rotating body;
When one of the even number of permanent magnets faces one permanent magnet, the other one faces a permanent magnet that is generating magnetic flux in the opposite direction to the direction of magnetic flux near that one permanent magnet. A flowmeter comprising a pair of magnetic flux detection members fixed to a fixed member, and a means for detecting magnetic flux generated by a permanent magnet and adding electric signals output from the pair of magnetic flux detection members.
