量計。 A plurality of reflective surface portions and non-reflective surface portions are arranged alternately in the circumferential direction on a non-circular gear mounted in the flow path, and a light emitting element and a light receiving element are provided outside the working chamber so as to face the reflective surface portion. In a non-circular gear flowmeter configured to measure a flow rate proportional to the rotation angle by measuring the rotation angle of the non-circular gear using a detection signal from a light receiving element, the reflective surface portion may When the non-circular gear is rotated by an angle at which the non-circular gear discharges a constant flow rate, each of the reflective surface portion and the non-reflective surface portion has a circumferential width that is integrally formed with the detection target plate, and a detection signal is generated from each of the reflective surface portion and the non-reflective surface portion. A non-circular gear type flowmeter characterized in that the flowmeter is set so that the flow is generated by the flowmeter.
