範囲第１項記載の非円形歯車式流量計。[Claims for Utility Model Registration] 1. A plurality of reflective surface portions and non-reflective surface portions are formed in a hole formed in one axial end surface of at least one of a pair of non-circular gears that are installed in an operating chamber and mesh with each other. Reflection plates arranged alternately in the circumferential direction are installed, and a light emitting element and a light receiving element are provided outside the working chamber so as to face the reflective surface part and the non-reflection surface part of the reflection plate. In a non-circular gear type flowmeter configured to measure the flow rate by detecting a pulse signal of a light receiving element as the gear rotates, the axially opposite side of the non-circular gear to which the reflector is attached A non-circular gear type flowmeter characterized in that a hole having substantially the same shape as the hole is formed in an end face of the non-circular gear type flowmeter. 2. The non-circular gear according to claim 1, wherein a balance member substantially the same as the reflector is installed in a hole on the opposite side of the reflector-installing hole of the non-circular gear. Gear type flowmeter.
