Description
本出願は、参照によりその全体が本明細書に組み込まれている、2015年11月24日に出願し「Method of Manufacturing a Weld−Less Coriolis Mass Flow Rate Sensor from a Polymeric Material」と題した米国特許仮出願第62/259,611号明細書の利益を主張するものである。
図1Aおよび1Bは、1つの実施形態による例示的なコリオリ質量流量計100の側面および背面の斜視図を示す。コリオリ質量流量計(本明細書では、「流量計」とも呼ばれる)100は、図5Aから6に関連して以下でさらに説明される方法に従って製造され得る。流量計100は、流れ感知部材102a〜bと、流れ感知部材102a〜bを保持する動的応答性支持体(本明細では、「支持体」とも呼ばれる)104とを含む。流れ感知部材102〜bは、中空であり、かつ、流体が流れるのを可能にする管状の横断面を有する。示された例では、流れ感知部材102a〜bは、それぞれ、曲線の形状を有し、かつ、同一のものである。この例では、それらは、支持体によって保持される真っ直ぐな管状脚部を含むU字形状のものである。曲線形状の流れ感知部材を使用することの1つの利点は、隅部が存在せず、そのため流体経路に沿った突然の方向の変化が存在しないことである。したがって、圧力降下の増大をもたらすかまたは支持体からの流れ感知部材の遊離をもたらし得る流れ感知部材内でのスラリー固形物の蓄積の可能性が、排除される。
支持体104は、流量計100のための構造上の支持を提供する。支持体104は、流れ感知部材102a〜bを保持し、かつ、流れ感知部材102a〜bと一体化される。下記のオーバモールド製造法においては、支持体104は、各流れ感知部材102a〜bの2つの脚部の外表面を挟持するように、しかし別体の接着剤の使用を伴わずに、流れ感知部材102a〜bと一体化される。支持体104は、第2のCTEを有する第2の材料で作られる。支持体104は、流れ感知部材の脚部上に第2の材料を成形するオーバモールドプロセスを使用することによって製作される。したがって、支持体104は、第2の材料の単体部品(single monolithic piece)で構成される。支持体104は、流れ感知部材102a〜bが貫通する管状のチャネルを含む。支持体104は、流れ感知部材102a〜bが通過することを可能にする、前方端部および後方端部上のポートをさらに含む。例えば、図1Bに示されるように、支持体104の後方端部は、ポート107を含む。図3Bに示されるように、支持体104の前方端部は、ポート109を含む。
図5Aから5Dは、支持体104が流れ感知部材102上にオーバモールドされ、したがって一体化されたコリオリ質量流量計を形成する、1つの実施形態による製造プロセスの斜視図を示す。図5Eは、対応する製造プロセスを示す流れ図である。図5Aに示されるように、ツーリング502が、オーバモールドプロセス中に流れ感知部材102bを所定の位置に保持550する。この例では、ツーリング502は2つの部品を含み、そのうちの一方は、流れ感知部材102の2つの脚部の端部を保持し、そのうちの一方は、流れ感知部材102のU形の曲り部(U-bend)を保持する。他のタイプのツーリングが明らかになるであろう。
図7は、1つの実施形態による、一体化されたコリオリ質量流量計組立体700を示す。流量計100は、電磁駆動機器組立体によって駆動される。電磁駆動機器は、横材704に取り付けられた磁石702、および、横材708に取り付けられたコイル706を含む。横材704、708は、流量計100の流れ感知部材102a、102bにそれぞれ取り付けられる。コイル706に適切な正弦波信号が印加されると、流れ感知部材102aおよび102bは、逆相モードで振動するように駆動される。
