Abstract
A fluid indicator for use in a containment vessel. A sensor body is movable by a drive relative to the vessel. An indicator automatically indicates the location of the sensor body relative to the vessel. A passage is in the body through which fluid from the vessel can be viewed and a light emitter is positioned in the body so as to direct a beam through the fluid. A light sensor also positioned in the body receives light after it passes through the fluid and produces a signal in response thereto.
Claims11
A fluid indicator for use in a containment vessel, comprising:
- a sensor body movable relative to the vessel;
- a drive connected to the body for moving it relative to the vessel;
- means for indicating the location of the body relative to the vessel;
- a passage in the body through which fluid from the vessel can be viewed;
- means including a light emitter in the body for directing a beam through said fluid, and
- means including a light sensor in the body for detecting the beam after it passes through the fluid and for producing a signal in response thereto.
A fluid indicator for use in a containment vessel, comprising:
- a tube of transparent material for connection to a vessel containing fluid;
- a sensor body movable along the tube;
- a drive connected to the sensor body for moving it along the tube;
- means for indicating the location of the sensor body along the tube;
- a passage in the sensor body through which fluid adjacent the first tube can be viewed;
- means including a light emitter in the sensor body for directing a beam through said tube and fluid;
- and
- means in the sensor body for detecting said beam after it passes through said tube and fluid.
A fluid indicator for use in a containment vessel, comprising:
- a first tube for connection to a vessel, a port in the tube for communicating fluid from the vessel to the first tube;
- a second tube of transparent material positioned within the first tube;
- a sensor body movable within and along the second tube;
- a drive connected to the sensor body for moving it along the second tube;
- means for indicating the location of the sensor body along the second tube;
- a passage in the sensor body through which fluid contained in the first tube can be viewed;
- means including a light emitter in the sensor body for directing a beam through said second tube and fluid;
- and
- means in the sensor body for detecting said beam after it passes through said second tube and fluid.
