Abstract
【解決手段】ピストンプルーバ1は、上流端3及び下流端4が形成された計測シリンダ2と、計測シリンダ2の下流端側と連結された油圧シリンダ12と、計測時に上流端3から流入された流体により計測シリンダ2内を上流側から下流側に向けて所定距離移動して基準体積の流体を排出する計測ピストン9と、油圧シリンダ12に移動可能に収容されたピストンロッド13とを備える。計測ピストン9とピストンロッド13とは別体で構成され、計測ピストン9を上流側の所定の計測準備位置に戻す際に、ピストンロッド13が計測ピストン9を下流側から上流側に移動させ、計測ピストン9を所定の計測準備位置にセットした後に、ピストンロッド13を油圧シリンダ12内に収容する。

Description
Claims (3)
- 流体を流入させる上流端及び該流体を流出させる下流端が形成された計測シリンダと、該計測シリンダの下流端側と連結された油圧シリンダと、計測時に前記上流端から流入された流体により前記計測シリンダ内を上流側から下流側に向けて所定距離移動して基準体積の流体を排出する計測ピストンと、前記油圧シリンダに移動可能に収容されたピストンロッドとを備えたピストンプルーバであって、
前記計測ピストンと前記ピストンロッドとは別体で構成され、前記計測ピストンを上流側の所定の計測準備位置に戻す際に、前記ピストンロッドが前記計測ピストンを下流側から上流側に移動させ、該計測ピストンを前記所定の計測準備位置にセットした後に、前記ピストンロッドのみを上流側から下流側に移動させて前記油圧シリンダ内に収容することを特徴とするピストンプルーバ。 - 請求項1に記載のピストンプルーバにおいて、前記計測ピストンは、周方向に埋め込んだ磁性体を有し、前記計測シリンダは、前記計測ピストンに埋め込まれた磁性体を検知する2つの検知手段を、前記計測シリンダの上流側と下流側に前記所定距離離して有することを特徴とするピストンプルーバ。
- 請求項1又は2に記載のピストンプルーバにおいて、前記計測シリンダの上流端及び下流端の両方に開閉可能な外気に連通する弁を備えたことを特徴とするピストンプルーバ。
