車式流量計のシール構造。 In a non-circular gear type flowmeter, a case body is equipped with a pair of non-circular gears that mesh with each other, and the flow rate of the fluid is measured by detecting the rotation of the non-circular gears as the fluid passes through using an optical rotation detection means. , the case body is composed of a lower case in which a non-circular gear is installed, a middle case in which a transparent lens is attached, and an upper case in which an optical rotation detection means is provided, and the upper case and the middle case are A sealing material is interposed between the upper case and the inner case, and one or both of the abutting surfaces of the upper case and the inner case are provided with a flow regulating groove for regulating the flow of the sealing material toward the side where the transparent lens is attached. A seal structure of a non-circular gear type flowmeter characterized by the following:
