Document Type and Number:
Japanese Patent JP2518785
Kind Code:
B2
Abstract:
PURPOSE: To provide a flow sensor of such type as an impeller is contained rotatably in a linear cylindrical body and the frequency of flux variation due to rotation of the impeller is detected by means of a detecting element mounted on the body in which detection accuracy can be enhanced while allowing downsizing of the sensor.
CONSTITUTION: An impeller 2 is coupled coaxially with an integral cylindrical body 23 while coupling each blade at the tip thereof. A guide tube 13 is disposed coaxially with the impeller 2 in the vicinity thereof on the upstream side in the body 1 with the inlet diameter of the cylindrical body 23 being set equal to or larger than the outlet diameter of the guide tube 13.
