Claims (4)
- 断面円形の収容凹部に対し流体の流入路と流出路とを備えたケースと、
円盤部の外周に羽根部を備えて前記ケースの収容凹部内に回転自在に収容支持され前記流入路から流入する流体を羽根部で回転方向に受け流量に応じて回転する薄板状の羽根車と、
前記羽根車の回転数を検出する回転数検出手段とを備え、
前記回転数検出手段は、前記円盤部の形態の変化で設けられた検出対象部と、
前記ケースに取り付けられて前記検出対象部を非接触で検出可能な隙間が該検出対象部に対して設定された近接センサとよりなり、
前記検出対象部の表面形態が前記円盤部の回転により前記近接センサに対し前記隙間で近接変化することにより検出信号を発し、前記羽根車の回転数に基づいて流量計測を行う流量計であって、
前記羽根部と前記収容凹部の内周面全周との間に、相対回転を許す前記羽根車の厚みを下回る僅かな隙間を形成し、
前記羽根車の中心部に嵌合孔を設けるとともに前記ケースに支持軸を支持して該支持軸に前記嵌合孔を回転自在に嵌合支持し、
前記羽根車の両側に、前記支持軸に嵌合支持され前記ケースと羽根車との間に前記羽根車の厚みを下回る僅かな隙間を形成するワッシャを配置し、
前記流入路の直径を、前記羽根車の厚みよりも小さな寸法に形成するとともに前記収容凹部の内周面よりも中心側に入り込んだ位置で該収容凹部に連通させて流入路の開口全体を前記羽根部に対向させた、
ことを特徴とする流量計。 - 請求項1記載の流量計であって、
前記検出対象部は、前記円盤部に凹部又は穴部を加工することにより設けられたことを特徴とする流量計。 - 請求項1又は2項記載の流量計であって、
前記流体の流入路は、前記羽根部に対向配置され、同流出路は、前記円盤部の回転中心部に対向配置されたことを特徴とする流量計。 - 請求項1〜3の何れかに記載の流量計であって、
前記流入路及び流出路は、塗装用のスプレーガンに塗料を供給する供給路に接続され、前記回転数に基づいて流量を表示する表示手段を備えたことを特徴とする流量計。
