Collapsible liquid level measurement device with attachments

Abstract

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.

1 . A liquid level measuring device for measuring liquid levels in containers, comprising: 
 an elongate handle;    an elongate frame arranged in telescoping relationship with the elongate handle, the elongate frame being movable between a collapsed position for storage and an extended position for usage;    a float arranged to be movable lengthwise along the elongate frame, the float having a passage therethrough;    a control rod arranged to extend lengthwise in the elongate frame and to extend through the passage in the float, the control rod being movable between a locked position in which the float is constrained against movement relative to the elongate frame and an unlocked position in which the float is free to move relative to the elongate frame; and    an actuator arranged to actuate 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.    
   
   
       2 . The liquid level measuring device of  claim 1 , further comprising means for collecting a sample of liquid from a container.
