Claims

[Scope of Claim for Utility Model Registration] (1) An impeller that rotates in accordance with the flow rate of the fluid to be measured within the main body, and an impeller provided at the center of the impeller with both ends located on the upstream and downstream sides, respectively. In a turbine-type flowmeter comprising a rotating member rotatably supported by a bearing part, the measured object is located upstream of the upstream bearing part at a position that does not impede the flow of the measured fluid in the main body. A turbine flowmeter equipped with a dust collection means to collect dust contained in the fluid. (2) The turbine flowmeter according to claim 1, wherein the dust collecting means is a filter member having magnetic force. (3) The filter member is a practical filter member composed of an annular base disposed inside the main body and a slit disposed within the annular base parallel to the flow direction of the fluid to be measured. Scope of patent registration request No. 2
Turbine flowmeter as described in section. (4) The turbine flowmeter according to claim 3, wherein the annular base is a magnet, and the slit portion is made of a magnetic material. (5) Each slit portion of the filter member has a shape that becomes wider from the upstream side to the downstream side, and a recessed portion is formed on the downstream end face. The turbine flowmeter according to any one of paragraphs.
