Magnetic level gauge

Abstract: A level gauge for determining the level of a liquid in a vessel includes lenticular lens assembly allowing a plurality of level indicator flags enclosed therein to be viewed from a wide angle. The indicator flags have an elongated body manufactured from a sheet of material, and form a central pocket for retaining a magnet, and pins on either end for mounting within a frame. A mounting frame positions the lens assembly whereby an open channel is formed between the lens assembly and a back plate. The mounting frame is mounted to the vessel using spacers forming an open gap between the mounting frame and vessel. The open channel and gap minimize the transfer of heat from the vessel to the level gauge. The passage of a float with a magnet on the liquid in the vessel rotates the flags.

Abstract: This invention relates to a tap assembly (10) for a liquid vessel (12), having an overfill protection device and a float controlled mechanical or magnetic level gauge (18). A single float (42) actuates a stem (57) of the overfill protection device as well as a rod (20) of the level gauge (18). The rod (20) of the level gauge (18) has one end movable linearly in a valve body bore (62) and carrying a permanent magnet (64) for actuating a magnetic level indicator (22). In one embodiment a crank mechanism may be provided between a float lever (44) and the rod (20) of the level gauge (18) to cause the rod (20) to effectuate a swinging movement and simultaneously displace the rod (20) longitudinally to cause linear displacement of the permanent magnet (64) in the valve body bore (62). In another embodiment the rod may be actuated by a cam to cause axial displacement thereof without swinging motion.

Abstract: PROBLEM TO BE SOLVED: To provide an optical magnetic level gauge with high detecting accuracy and not requiring specific explosionproof structure even when being used in liquid having the danger of explosion. SOLUTION: A float 2 having a magnet 3 is installed on the outside of a stem 1. A magnetic optical sensor 4 detecting magnetism of the magnet 3 and converting it into a light signal is set onto the inside of the stem 1, optical fibers 11, 12 connected to the magnetic optic sensor 4 are drawn out to the upper end part of the stem 1, and a light emitting element 13 and a light receiving element 14 are fixed. Since transmission loss of a signal is small and no electric spark is generated, specific explosionproof structure is unnecessary even when being used in liquid having the danger of explosion.

Abstract: The utility model provides a modular magnetic level gauge, be in including urceolus assembly, setting magnetic floater and connection in the urceolus assembly are in the magnetism in the urceolus assembly outside turns over the board, urceolus assembly inner wall reaches the magnetic floater outer wall is provided with compound release coatings, the urceolus assembly is formed through flange jointby the multistage barrel. The utility model provides a pair of modular magnetic level gauge can effectively avoid easy adhesion medium and tiny catalyst adhesion on connecing the liquid part, and canbe according to the nimble length that makes up magnetic level gauge of the distance between the liquidometer connected mouth on tower or the container.
