摘要： A system comprises a rod placed inside a tank and configured to move a pre-configured distance as the level of a gas stored in the tank changes. A chamber is positioned in relation to a top region of the tank. A magnet is coupled to an upper portion of the rod and disposed inside the chamber such that the magnet moves with the rod. A circuit board is positioned adjacent to the chamber and includes two sensors positioned along the length of the chamber, wherein each sensor generates a voltage signal corresponding to a strength of magnetic field associated with the magnet. A memory stores voltage values corresponding to the voltage signal and a processor coupled to the memory calculates a volume of the gas in liquid form in the tank based on a voltage value generated by at least one of the sensors.

摘要： An electronic liquid level gauge assembly includes an electronic display located in a housing connected to a tank. The display has first and second display portions for indicating liquid level condition. A first electronic sensor senses a change in magnetic field of a magnet associated with a liquid level transducer, with magnet rotation being proportional liquid level change. A processor determines a temperature-compensated liquid level condition by correlating the liquid level signal with temperature measurement of the liquid. A temperature-compensated vapor space can also be calculated based on tank information and properties of the liquid. Signals related to the temperature-compensated liquid level and vapor space are sent to the display and wirelessly transmitted to a smart phone or the like for remotely viewing the tank information. The smart phone also includes a special app for sending information, firmware updates, and display configuration data to the electronic gauge assembly.

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： 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： 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.
