Abstract
A level indicating assembly for use in a tank mounted in a vehicle, such as an RV or boat, includes a fitting body for mounting the assembly in the top of the tank, and probes extending through the body into the tank. At least one of the probes has a hollow probe shaft which is of a flexible material such as flexible pvc. One of the probes provides an "empty" indication for the tank, while the other probes provide a "full" indication, and a mid-level indication. A socket or like element with a knock-out plug optionally provides a vent in the fitting body. During installation the position of the probe shafts with respect to the fitting body are adjusted, and any unneeded portion of the probe shaft above the shaft fitting is cut off.
