ABSTRACT:
A dip stick for measuring the amount of liquid in a deep container such as a gasoline storage tank. The dip stick includes a long, transparent tube mounted to a wooden stick, a linear scale for indicating the height of liquid in the tube, a valve element disposed at the bottom portion of the tube and a wire extending from the valve element through the tube to the top of the tube. Structure is provided at the top of the tube for raising and lowering the wire and the valve element to close the portal. After inserting the dip stick into the tank and closing the tube portal, the volume of liquid in the tank is determined by viewing the height of liquid in the tube.
