Claims

[Scope of utility model registration request]

When passing through the tapered tube, a magnetic float floating inside the tube stops at a certain position depending on the flow rate, and a magnetic indicator ring that moves to follow the float is placed on the outside of the tapered tube. In the flowmeter provided, a wavy groove is provided on the outer periphery of the tapered pipe, and a protrusion is provided on the indicator ring that engages with the wavy groove, so that the indicator ring follows the movement of the float while rotating from side to side. A floating flowmeter characterized by the following features:
