Abstract
A flow dampener for dampening pulsation in a fluid flow includes a body shell, a flexible membrane, and two flow ports. The body shell has an interior surface and an elongate groove formed on the interior surface. The flexible membrane is sealed to the interior surface of the body shell and covers the elongate groove. In some embodiments, the flexible membrane is over-molded onto the body shell. The flexible membrane cooperates with the elongate groove to form an elongate flow path for the fluid flow. The flexible membrane has a thickness in a range from 0.5 mm to 6 mm. As the membrane is flexible, it vibrates as the fluid flows through the elongate flow path, absorbs kinetic energy in the fluid flow, and thereby dampens pulsation in the fluid flow.
Claims21
A flow dampener comprising:
- two sections, each section comprising:
- a body shell having an interior surface and an elongate groove formed on the interior surface;
- and
- a flexible membrane sealed to the interior surface of the body shell and covering the elongate groove, the flexible membrane cooperating with the elongate groove to form an elongate flow path, the elongate flow path having two ends, wherein flexibility of the membrane dampens vibration in a flow of fluid through the elongate flow path;
- two external flow ports, one external flow port to one end of the elongate flow path in each section;
- and
- a through flow port providing a flow path between the other ends of the elongate flow paths.
A flow dampener comprising:
- a body shell having an interior surface and an elongate groove formed on the interior surface;
- a flexible membrane sealed to the interior surface of the body shell and covering the elongate groove, the flexible membrane cooperating with the elongate groove to form an elongate flow path, wherein flexibility of the membrane dampens pulsation in a flow of fluid through the elongate flow path;
- and
- two flow ports to the elongate flow path, each of the two flow ports connected to one end of the elongate flow path.
A flow system comprising:
- a Coriolis flow sensor configured to measure one or more flow characteristics of a fluid flowing through a flow path provided by the Coriolis flow sensor;
- and
- a flow dampener comprising:
- a body shell having an interior surface and an elongate groove formed on the interior surface,
- a flexible membrane sealed to the interior surface of the body shell and covering the elongate groove, the flexible membrane cooperating with the elongate groove to form an elongate flow path, the elongate flow pathing having a first end and a second end, wherein flexibility of the flexible membrane dampens pulsation in a flow of fluid through the elongate flow path,
- an inlet flow port connected to the first end of the elongated flow path, and
- an outlet flow port connected to the second end of the elongated flow path and the flow path provided by the Coriolis flow sensor.
