摘要： An exterior gauge component is used to indicate a tank liquid level based on a rotational orientation of a tank magnet at a gauge head. The exterior gauge component includes a multi-track rotary encoder wheel and an optical sensor configured for reading an output of the multi-track rotary encoder wheel. The multi-track rotary encoder wheel is configured to rotate with rotation of the tank magnet such that specific ranges of rotational orientation of the tank magnet each corresponds to a specific output of the multi-track rotary encoder wheel. Each track represents a binary bit of the output read by the optical sensor. An adapter plate mounts a housing of the exterior gauge component to the gauge head and has an opening therethrough. A proximal end portion of the housing including magnets extends through the opening, and is detachable from the housing and attachable to a threaded adapter for mounting to a threaded opening of a tank.

摘要： A liquid fuel level sensing device disclosed herein may include: a holder; an arm fixed to the holder; a cover fixed to the holder to cover the arm; and a float connected to the arm outside the holder. The holder may include a bottom portion and a first snap fit structure, which may include a pair of support portions provided with an interval therebetween, and provided on the bottom portion. First and second interval portions may be provided between the pair of support portions, the first interval portion may hold the arm, and the second interval portion may be provided above the first interval portion and be narrower than a width of the arm held in the first interval portion. The cover may include a deformation restricting portion provided at a position facing an outer surface of at least one of the pair of support portions.

摘要： One embodiment of a fuel tank assembly includes a fuel sending unit having a float with a small thickness, which heretofore has been too thin to secure a stand-alone magnet thereon. The float may be manufactured in a complex shape or in a small size. In one embodiment the float may be manufactured of a material having magnetized particles interspersed throughout the float such that the float does not require a stand alone magnet secured thereon. The float may be manufactured of a material having a foaming agent added thereto so as to provide a finished product with air filled voids positioned throughout the float to increase the buoyancy of the finished float product.

摘要： A liquid level detecting device includes a sensor housing having a circular rotation recess, a circular holder which is fitted in the rotation recess and held rotatably by the sensor housing, a float arm, a float, a magnet, and a Hall element. The sensor housing has a lock groove and a pair of insertion holes. The holder has a pair of flanges which project in opposite directions from an outer circumferential surface of the holder and are engaged with the lock groove and prevented from coming off the rotation recess by setting the flanges opposed to the respective insertion holes, fitting the flanges into the rotation recess, and then rotating the flanges. The holder has a pair of support projections which come into contact with a bottom surface of the rotation recess.

摘要： Subsea equipment-protection apparatus including a fluid monitoring apparatus for detecting a first fluid, a second fluid and a third fluid. The fluid monitoring apparatus including a first float having a density less than that of the first fluid but greater than that of the second fluid; a second float having a density less than that of the second fluid but greater than that of the third fluid; and a sensor configured to detect the first and second floats so that the position of the floats can be determined. The first float floating when a fluid with density greater than the first float is present and sinking when a fluid with density less than the first float is present. The second float floating when a fluid with a density greater than the second float is present and sinking when a fluid with a density less than the second float is present.

摘要： A filling level indicator for determining a filling level in a tank, having a resistor network arranged on a carrier substrate, a contact element, and a magnetic element. The contact element is arranged adjacent to the resistor network and the magnetic element is movable relative to the resistor network and the contact element. The contact element has a contact region deflectable by the magnetic element. An electrically conductive connection between the contact region and the resistor network is produced by the deflection of the contact region. The contact element has an attachment region connected to the carrier substrate, and the contact region is formed spaced apart from the resistor network and the carrier substrate.

摘要： A liquid level detection device is provided with a fixed body and a rotating body, having a float and an arm. The arm has an insertion portion inserted in the rotating body and an extending portion extending straight and bent relative to the insertion portion. The rotating body has an insertion hole in which the insertion portion is inserted, a holding portion having a receiving opening receiving the extending portion and holding the extending portion received by the receiving opening, and a stopper releasing the receiving opening from a blocking state in which a blocking portion blocks the receiving opening. The stopper has a sliding surface portion on which the extending portion is allowed to slide. A thickness of the blocking portion at a tip end of the sliding surface portion is greater than a diameter of the extending portion.

摘要： A level sender for a tank includes a sensor device. A driven member is associated with a float assembly. The sensor device is adapted to determine a level of fluid within the tank based on an angular position of the driven member. A float arm is coupled to a float at a first end and is coupled to the driven member at a second end.

摘要： A liquid level detecting device includes a sensor housing, a holder held rotatably by the sensor housing, a float arm fixed to the holder, a float attached to the float arm and following a surface level of liquid stored in a tank, a magnet provided in the holder, and a Hall element detecting a displacement of the magnet. The float arm is fixed to the holder so as to extend in a direction perpendicular to a rotation axis of the holder. The sensor housing has stoppers which restrict a rotation angle range of the holder to a first rotation angle by bringing a portion of the float arm, which is positioned between a tip of the float arm and the rotation axis, into contact with one of the pair of first stoppers.

摘要： A fluid level sensor includes a magnetic field generator that generates a magnetic field varying with time. A metallic member is disposed in a region in which the magnetic field generated by the magnetic field generator is present. The metallic member is movable relative to the magnetic field generated by the magnetic field generator based upon a fluid level to be measured. The metallic member has an effective geometry defining the magnitude of eddy currents induced in the metallic member due to the magnetic field generated by the magnetic field generator. The effective geometry is changed when the metallic member is moved relative to the magnetic field generator. A sensing device detects the eddy currents induced in the metallic member, and a fluid level determination device determines the fluid level based on the eddy currents induced in the metallic member. A method of use of the device is also disclosed.
