摘要： An apparatus and method for determining the amount of liquid contained in a railroad tank car, or any other liquid storage tank having an interior region defining a predetermined relationship between liquid level and volumetric content. A tube having a closed bottom end is disposed within the tank in a substantially vertical orientation with the closed end of the tube emersed in the liquid and the open end of the tube protruding from the top of tank. An elongate member having a longitudinal edge defining a varying profile corresponding to the predetermined relationship between liquid level and volumetric content is slidably received within the tube. A float is slidable vertically along the exterior of the tube and is magnetically coupled to the elongate member such that as the float rises or falls in response to a change in liquid level, the elongate member will be vertically displaced within the tube. A measuring device positioned proximate the open end of the tube measures the distance between the longitudinal edge of the elongate member and a reference plane aligned substantially parallel to the longitudinal axis of the elongate member, the distance being directly proportional to the volumetric content of liquid contained in the tank. The measurement signal generated by the measuring device is proportionately converted into a standard volumetric unit of measurement by way of a signal multiplier. The volume of liquid contained in the tank may then be indicated on a remote display.

摘要： A liquid level monitoring and control apparatus is described, which generates an alarm signal or a safety signal, discontinuing an operation such as heating, when the liquid level in a controlled vessel has reached a predetermined level. Several signals, similar or different, may be generated at different liquid levels. The operation of the. apparatus may be based on various physical properties, such as optical, magnetic, acoustic, electrical and conductivity properties. The apparatus comprises a floating actuator, the level of which is determined by the level of the liquid in the vessel, a sensing assembly comprising at least a member which can be actuated by the actuator, means for guiding the vertical displacement of the actuator and means for issuing the desired signal or signals when the actuator reaches a level close to that of the actuatable member. The actuatable member can be displaced to set the predetermined level of the liquid as desired by the user. The apparatus can be so designed as to constitute a transportable kit comprising the actuator and the actuatable member. In a form of the invention, the actuator is mounted on a floating rod. In another modification of the apparatus, the meniscus of said liquid serves as the actuator.

摘要： An object of the present invention is to provide a master cylinder which decreases the number of necessary parts, achieves easy assembly and stabilized quality, and surely prevents a float from coming off. In the present invention, the master cylinder tank 20 contains working fluid in the interior of a tank body 21 and incorporates a float 25 movable vertically in response to the increase and decrease in the working fluid by being guided by a float guide 22, and coming-off preventive portions 24, 24, capable of being deformed elastically, are provided to cover at least a part of the float 25 by extending a part of the float guide 22 upward beyond a guide rib 23. The coming-off preventive portions 24, 24 are formed by being bent to the inside into a shape such as to partially cover the float 25, so that the float 25 is prevented from coming off by the coming-off preventive portions 24, 24.

摘要： The gauge has an outer tube sealed at its lower end and adapted for attachment to the top wall of the tank. The gauge also has an inner tube axially movable within the outer tube. A float encircles the outer tube. Magnets respectively attach to the float and to the lower end of the inner tube, whereby a rising liquid causes the inner tube to rise as well. When the liquid level reaches a predetermined high level, a pencil-type magnet mounted within the inner tube operates a switch in an alarm box mounted in the top of the outer tube.
