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： An apparatus for testing the functioning of a float-activated liquid level control device comprises a float for activating a liquid level control device, a float cage enclosing said float, an entry port accessible from outside a separating tank through which fluid may be input directly into the float cage enclosure, and a flange connection for mounting the test apparatus inside a fluid separation tank. The method comprises connecting a fluid source to the input port of the apparatus of the instant invention, injecting fluid directly into the float cage enclosure to activate the float of the instant invention, monitoring the liquid level control device to insure that it is functioning correctly and then withdrawing the input fluid to return the float to its normal operating position.

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.

摘要： A liquid level indicator has a level monitor arranged in a chamber adapted to be connected in parallel with a container for the liquid whose level is to be indicated. An artificial liquid level is formed in the chamber by introducing liquid or gas depending on whether the indicator is intended to indicate a too high or too low liquid level. The liquid or gas used is allowed to escape into the container, thereby testing the level monitor even when it is part of an operating system.

摘要： An SCR system that can detect whether or not a float is stuck even where a water level sensor that detects a liquid level in a stepwise manner is used is provided. The SCR system includes: a urea injection quantity integrating unit 2 that integrates an injected quantity of urea to calculate a urea injection quantity integrated value; an integrated value resetting unit 3 that if a detected value from detection means 202 changes, resets the urea injection quantity integrated value; and an abnormality determination unit 4 that if the urea injection quantity integrated value exceeds a predetermined threshold value for determination, determines a level sensor 120 as having an abnormality.
