ABSTRACT:
In a device for indicating the level of a liquid in a reservoir of the type which has a liquid receiving area to be positioned partially within the liquid in the reservoir, a liquid confinement tube within the liquid receiving area which may be moved from a liquid unconfining position to a liquid confining position when it is desired to measure the level of the liquid in the reservoir, a piston within the liquid confinement tube coupled to an indicator located outside the reservoir such that movement of the indicator causes movement of the piston within the confinement tube, the amount of movement of the piston and indicator indicating the level of fluid within the reservoir, and a spacer tube determining the length between the liquid receiving area and the indicator, the improvement of making the device adjustable over a range of lengths. To make the device adjustable, the spacer tube is length adjustable and may include telescoping tubes, and the coupling between the piston and indicator is also length adjustable, the coupling being released while adjustment of the spacer tube takes place. It is also preferable to secure the confinement means in unconfining position during the adjustment of the device. When the device replaces a dipstick in a liquid reservoir, the invention includes a method of adjusting the length of the device by aligning portions of the device with corresponding portions of the dipstick.
