Title: Helmut W Hopfe: Innovator in Fluid Meter Technology
Introduction
Helmut W Hopfe is a notable inventor based in Erie, Pennsylvania, recognized for his contributions to fluid meter technology. With a total of three patents to his name, he has made significant advancements in the field, particularly in the design and functionality of fluid measurement devices.
Latest Patents
One of his latest patents is for a temperature compensated rotary meter. This innovative fluid meter includes a temperature transducer with a bellows that expands and contracts. The movement of a rod attached to the bellows is coupled to a transmission assembly, which consists of a cylinder and a cone with a transfer ring mounted between them. The actuator rod is interconnected with the transfer ring, allowing it to move linearly and continuously along the axis of the cylinder in response to temperature changes in the fluid being measured. This mechanism adjusts the speed of rotation of the cone relative to the cylinder, ensuring accurate measurement of fluid volume as temperature varies. Additionally, the design incorporates elastomeric expanders that flex in response to forces exerted on the cone, minimizing the effects of discontinuities during rotation. The register cover attached to the fluid meter features side ribs and closure ribs that enhance its structural integrity.
