摘要： The invention is concerned with a float operated signalling device in which a magnet follows the movement of a float in a closed liquid container, the magnet reciprocating in a non magnetic tube through which it operates signal controls. An auxiliary liquid supply is connected to the tube for providing a temporary hydraulic pressure differential across the piston or a part attached to the piston so that the float is dunked below the liquid level and the magnet operates the signal controls for test purposes.

摘要： The invention is concerned with a float operated signalling device of the kind in which a magnet follows the movement of a float in a liquid container and operates signal controls through a non magnetic wall. An open topped pan having a drain opening is attached to the magnet/float assembly and an auxiliary liquid supply is provided for depositing liquid into the pan at a rate greater than that at which it can drain out of the pan. When the pan contains liquid the float is dunked below the liquid in the container so that the magnet operates the signal controls for test purposes.

摘要： A method for a fuel system comprises receiving a first indication of inconsistency in a fuel level indicator output during a fuel consumption cycle, receiving a second indication of inconsistency in a fuel level indicator output during a refueling event, and indicating electrical degradation of the fuel level indicator responsive to the first and second indications of inconsistency indicating coincident ranges of inconsistency for the fuel level indicator output. By gauging the consistency of a fuel level indicator output during both upward and downward travel, electrical degradation may be distinguished from mechanical degradation. In this way, a range of inconsistency may be determined, and a reported fuel level adjusted while the fuel level indicator output is within the range of inconsistency.

摘要： To determine a failure of a float switch for detecting whether or not the oil level is less than or equal to a predetermined oil level. A predetermined oil level OLth is set between a normal oil level and a minimum oil level in view of the fact that when the oil level in an oil pan is normal, the oil level is decreased from the normal oil level to the minimum oil level during a predetermined time period just after starting an engine. When a float switch is not changed from an OFF position to an ON position during the predetermined time period after starting the engine, it is determined that the float switch suffers a failure or the oil level is excessive.

摘要： A method and apparatus for measuring a liquid level by a float carrying one or more magnets and movably positioned adjacent spaced analog output voltage Hall-effect sensors. The apparatus is calibrated by moving the float relative to the sensors and measuring the voltage outputs of the sensors relative to the position of the float, and storing the measured values. After calibrating, the voltage outputs of any sensors activated by the presence of the float are measured and compared to the stored values to determine the liquid level. Preferably, the voltage output of at least two sensors are measured while the float is at one position for greater accuracy.

摘要： A marine craft includes a pollution control device for marine fuel tanks. The pollution control device includes a compartment for receiving fuel that leaves the fuel tank headed toward the vent via the vent line. The volume of the compartment desirably holds more fuel than would be contained in the volume of the length of the vent line that extends from the fuel tank to the vent. The compartment has an inlet that communicates with the fuel tank via the vent line. The compartment has an outlet that communicates with the vent via the vent line. The device includes a guide tube disposed within the compartment for preventing direct transmission of fuel to the vent. The device includes a float member disposed within the guide tube for detecting fuel in the vent line. The device includes an alarm circuit activated when the float member is located at a predetermined position within the guide tube. The device includes a lifting arm connected to the float member and enabling the float member to be lifted to a position where the operative alarm circuit should activate a signal.

摘要： In combination with a fluid reservoir in which a magnetically operable switch is assembled to be closed by magnetic force of a permanent magnet on a float such that a warning signal is issued when the float moves down to a lower warning position dependent on a minimum fluid level in the reservoir, a check mechanism includes a spring loaded vertical rod extending into the interior of the reservoir from the exterior and arranged to be engaged at its lower end with the float when the surface of fluid is maintained at a predetermined level. When the vertical rod is pushed downward, the float is forcibly moved down to the lower warning position to check malfunction of the switch.
