摘要： A float is arranged in a tubular frame to be unlocked to float in a liquid when the lower end of the frame contacts a bottom surface of a container containing the liquid. A float lock guide and a float lock actuator are mounted in the passage to move the float laterally in the frame as the lower end of the frame is moved away from the bottom surface of the container to lock the float in frictional engagement with the frame.

摘要： A liquid level sensor for insertion into a tank for measuring the liquid level in the tank comprises an elongate tubular frame and a float movable inside the frame to seek the liquid level. A float lock guide formed as an elongate member is mounted lengthwise inside the frame. A float lock formed as an elongate member is located inside the frame parallel to the float lock guide. A plurality of linkages is pivotally connected between the float lock guide and the float lock such that lengthwise movement of the float relative to the float lock guide causes corresponding lateral movement of the float in the frame between an unlocked position where the float is free to move lengthwise in the frame to seek the liquid level and a locked position where frictional forces retain the float between the float lock and an inner wall portion of the frame.

摘要： A liquid level measuring system includes a housing mounted to a container and a flexible coupling connected between the housing and a tubular frame suspended in a container holding a liquid. The flexible coupling maintains the tubular frame in a vertical orientation in the container. The tubular frame has a pair of 270° rifling grooves therein. A float is mounted in the tubular frame. The float has a pair of projections that extend from opposite sides portion thereof into the rifling grooves so that the float is force to rotate as it moves vertically in the tubular frame to seek the liquid level. A magnetic coupler assembly transfers movement of the float to an indicator. The magnetic coupler assembly includes a pair of facing dielectric discs. Each dielectric disc has three magnets mounted thereon with opposite poles facing one another.

摘要： An adjustable liquid level measuring device for measuring the level of a liquid in a variety of container configurations. The device has an indicator means for mounting on a container for providing a visual reading related to the level of the liquid in the container. The device has a frame connected to the indicator means and a buoyant float adapted for floating on the surface of the liquid in the container. The device has an endless flexible chain with a first loop adjacent to the indicator means and another portion connected to the buoyant float. The chain also has a loop movably mounted on the frame so that movement of the float moves the first loop relative to the indicator means. The indicator means is connected to have an indicator dial pointer moved by the movement of the first loop. The frame has first and second elongated frame sections with the first frame section being adapted for mounting on the wall of a container and the second frame section being adapted to extend toward a position adjacent the lowest point of the interior of the liquid container. A pivotal connection between the first and second frame sections provides for 90.degree. angular displacement of the frame sections so that the device can be in an end and top reading mode on a container.

摘要： A liquid level measuring device includes an elongate handle and an elongate frame arranged in telescoping relationship. The frame is movable between a collapsed position for storage and an extended position for usage. A float is movable lengthwise along the elongate frame. A control rod extends lengthwise in the elongate frame and through a passage in the float. The control rod controls movement of the float relative to the elongate frame. An actuator actuates the control arm to move the float from the locked position to the unlocked position in response to a downward pressure between a lower end of the elongate frame and a bottom surface of the container so that the float is free to seek the liquid level in the container and to move the float from the unlocked position back to the locked position when the downward pressure is released.

摘要： A liquid level sensor for measuring liquid levels in underground and above ground containers includes a frame formed to have an elongate hollow tubular configuration that encloses a cavity. A cam pivot has an end extending into the cavity from a first inner wall portion of the frame. A cam is arranged to be pivotal about the end of the cam pivot. A float is placed in the cavity. A spring is arranged to bias the cam arm into contact with the float to force a side portion of the float into a locked position in frictional engagement with the second inner wall portion of the frame. A cam actuator pivotally mounted in a lower end portion of the frame exerts a force on the cam arm to release the float from the locked position when the lower end of the frame contacts the container bottom.
