A liquid level measuring device having an elongated frame is disclosed. One or more floats are mounted in the frame on cables mounted between pulleys at each end of the frame. Brake pins frictionally engage the guide cables and means are provided to selectively disengage the brake pins from the guide cables. A thermometer may be attached to the frame to provide temperature readings. Also, a timing device may be attached to the frame to provide the proper duration for obtaining exact temperature and liquid level(s) measurements.
