Abstract
An apparatus for use in measuring a property of a fluid and a method of measuring a property of a fluid in a conduit. The apparatus is for use in measuring a property of a fluid, the apparatus comprising: a conduit comprising an inlet through which fluid can enter the conduit; a movable member retained within the conduit, the movable member configured to move in accordance with the property of the fluid in the conduit; and a magnetic field generating unit for generating one or more magnetic fields in the conduit, an interaction between the movable member and the one or more magnetic fields being detectable via the magnetic field generating unit, to measure the property.
Claims16
An apparatus for use in measuring a property of a fluid, the apparatus comprising:
- a conduit comprising an inlet through which the fluid can enter the conduit, the conduit comprising a first end and a second end;
- a movable member retained within the conduit, the movable member configured to move in accordance with the property of the fluid in the conduit;
- a magnetic field generating unit for generating one or more magnetic fields in the conduit,
- an interaction between the movable member and the one or more magnetic fields being detectable via the magnetic field generating unit, to measure the property of the fluid;
- and
- one or more magnet pairs for urging the moveable member away from one or both of the first end and the second end of the conduit, a first magnet of a magnet pair of the one or more magnet pairs being provided at the first end or the second end of the conduit, and a second magnet of said magnet pair of the one or more magnet pairs being provided at a corresponding end of the moveable member.
A method of measuring a property of a fluid in a conduit, the conduit comprising an inlet through which fluid can enter the conduit, the conduit comprising a first end and a second end, and the conduit retaining a moveable member configured to move in accordance with the property of the fluid, one or more magnet pairs being configured to urge the moveable member away from one or both of the first end and the second end of the conduit, a first magnet of a magnet pair of the one or more magnet pairs being provided at the first end or the second end of the conduit, and a second magnet of said magnet pair of the one or more magnet pairs being provided at a corresponding end of the moveable member, the method comprising:
- generating one or more magnetic fields in the conduit;
- exposing the movable member to the fluid;
- and
- detecting an interaction between the moveable member and the one or more magnetic fields, to measure the property of the fluid.
