一種內部具導流板之流量計，包括有：一本體，具有一組供流體流進及流出之管口及一向上通出之插口，該等管口間連通形成一供流體流經之通道；一計量裝置，具有一位於上部之計量單元及一位於下部之葉輪，裝設於該插口內並與插口周圍之壁體作密水式之固定性接合，使計量單元之部分外露於插口上，而葉輪之部分則伸入插口內，並且部份進入通道內；及一導流板，成型於供流體流入之管口端內的通道內壁上方向下突起，導流板設於鄰接葉輪之處並向供流體流入之管口端延伸，鄰接葉輪之側更區分為二邊之壁體為厚度較高之深導壁，及中間對應葉輪之部份為厚度較低之淺導槽；向供流體流入之管口端延伸出時厚度逐漸變少，最後與通道內壁貼平。
A flowmeter with a baffle inside comprises: a body having a plurality of nozzles for fluid to flow in and out and an outlet for upward passage, wherein the nozzles communicate to form a passage for fluid to flow through a metering device having an upper metering unit and a lower impeller mounted in the socket and fixedly engaged with the wall around the socket to expose a portion of the metering unit to the socket And the portion of the impeller extends into the socket and partially enters the passage; and a deflector is formed to protrude downwardly above the inner wall of the passage in the nozzle end into which the fluid flows, and the deflector is disposed adjacent to the impeller And extending to the mouth end of the fluid supply flow, the side adjacent to the impeller is further divided into two sides, the wall is a deeper guide wall having a higher thickness, and the middle corresponding impeller is a shallow guide groove having a lower thickness; The thickness gradually decreases as it extends toward the nozzle end into which the fluid flows, and finally aligns with the inner wall of the passage.
