Abstract
A self-rotating flow meter includes a housing, a rotating mechanism and a sensor. The rotating mechanism is disposed in a chamber of the housing between an inlet port and an outlet port. The sensor is disposed in the housing and near the rotating mechanism. The rotation mechanism contains inflow and outflow passages in a rotating shaft and a rotating disk respectively. The inlet flow passage has a centerline that is coincident with or parallel to the centerline of the rotating shaft. The centerline of any outlet flow passage in the rotating disk and the centerline of the rotating shaft are in two different planes and have a distance between them.
Claims13
A flow meter comprising:
- a housing including an inlet port, an outlet port, and a chamber located between the inlet port and the outlet port;
- a rotating mechanism disposed in the chamber and comprising:
- a rotating shaft rotatably supported by the housing,
- a rotating disk attached to the rotating shaft,
- an inflow passage located inside the rotating shaft, and
- one or more outflow passages disposed in the rotating disk, each outflow passage having an inner end fluidly communicating with the inflow passage and an outer end opening onto an outer periphery of the rotating disk, each outflow passage having a centerline which extends linearly from the inner end to the outer end of the outflow passage and which lies in a plane which is parallel to a plane containing a rotational centerline of the rotating shaft,
- wherein when fluid flows through the inflow passage and out of the one or more outflow passages, the fluid rotates the rotating mechanism;
- and
- a sensor positioned to measure the rotational speed of the rotating mechanism.
A flow meter comprising:
- a housing including an inlet port, an outlet port, and a chamber located between the inlet port and the outlet port;
- a rotating mechanism disposed in the chamber and comprising:
- a rotating shaft supported by the housing for rotation with respect to the housing about an axis of the rotating shaft and for movement within the housing with respect to the housing in the axial direction of the rotating shaft,
- a rotating disk attached to the rotating shaft,
- an inflow passage located inside the rotating shaft,
- a connecting flow passage located inside the rotating shaft and having a first end connected to the inflow passage and a second end opening onto an outer peripheral surface of the rotating shaft, and
- one or more outflow passages located in the rotating disk and extending to an outer periphery of the rotating disk;
- and
- a sensor positioned to measure the rotational speed of the rotating mechanism,
- wherein the rotating mechanism is movable with respect to the housing in the axial direction of the rotating shaft between a first position in which the second end of the connecting flow passage fluidly communicates with an interior of the housing to enable fluid to enter the connecting flow passage from the inlet port and flow into the inflow passage, and a second position in which the second end of the connecting flow passage is blocked by a portion of the housing to prevent fluid within the housing from entering the connecting flow passage.
