Patent number: 5743138Abstract: A float device is disclosed with an improved external surface having an outwardly concave curvature and a plurality of elongated grooves spirally formed on the concave surface. The concave surface provides improved clearance between the float device and the walls of the pipe that it is disposed in. Therefore, the float device is less subject to being lodged or stuck especially in highly viscous liquids. The spiral grooves provide additional passageway and stability by imparting rotational torque to the floating device when measuring flow rates in moving fluids in pipes. In another embodiment, the float device is annular in shape having an inner surface with a curvature and spiral grooves. Same improved effects are obtained as the float device rides up and down a column like a collar in measuring the fluid level or fluid flow rates.Type: GrantFiled: January 22, 1997Date of Patent: April 28, 1998Assignee: Chartered Semiconductor Manufacturing Ltd.Inventor: Wei Hua Cheng

Patent number: 5435181Abstract: Disclosed herein is an electronic float gauge for indicating the level of liquid in a tank. A float follows the liquid level and causes a rotor that has magnets on it to rotate. Surrounding the magnets, in a concentric array, are a series of reed switches. The rotation of the magnets feeds information to the reed switches about the level of fluid in the tank. The reed switches are connected to a fluid level indicator.Type: GrantFiled: September 29, 1993Date of Patent: July 25, 1995Assignee: The Kelch CorporationInventor: Ronald E. Koebernik

Patent number: 5410913Abstract: For liquid-level sensing in a tank, the invention provides a tank-mounted first subassembly that is adapted for suspension of a vertical guide from the top of the tank, such that a guided float may coact with an elongate vertical ribbon, to angularly displace a magnetic element carried by the upper end of the ribbon. The tank-mounting of this first subassembly completes closure of the tank and its contents, and closure structure of this first subassembly assures containment of the ribbon and its magnetic element within the closed volume of the tank. A second subassembly of magnetically responsive electrical means is encapsulated by a housing which is detachably connectable to the closure structure of the first assembly, solely by access that is external to the closed tank. Electrical output of the second subassembly is flexibly available to remote indicating and/or monitoring circuitry which forms no part of the invention.Type: GrantFiled: December 15, 1993Date of Patent: May 2, 1995Assignee: Thomas G. Faria CorporationInventor: David A. Blackburn

Patent number: 4838083Abstract: A float activated gauge for indicating the level of liquid in a tank utilizes a twisted float following member. The float following member is disposed adjacent to the float and is caused to rotate as the float moves vertically due to a change of the level of liquid in the tank. A U-shaped main body for the gauge guides the float vertically, holding the float captive and against the float following member. A needle extends at a right angle from the float following member and is externally visible to provide an indication of the amount of rotation of the float following member and, therefore, the level of liquid in the tank.Type: GrantFiled: January 22, 1988Date of Patent: June 13, 1989Assignee: Kelch Corp.Inventor: James E.

Patent number: 4724706Abstract: There is disclosed a fuel tank gauge of the type having a sensor such as a float for sensing the level of fuel in the tank. The float drives a fuel level indicator. The indicator is visible from the exterior of the tank when the sensor is installed in the tank. A first scale is positioned adjacent to the indicator so that the position of the indicator relative to the first scale indicates the level of fuel in the tank. A second scale is also adjacent to the indicator so that the position of the indicator provides information with respect to the amount of oil needed to be added to the tank. Accurate gas/oil fuel mixtures can be prepared directly in the tank through the use of the invention.Type: GrantFiled: December 22, 1986Date of Patent: February 16, 1988Assignee: Kelch Corp.Inventor: Michael E.
