ABSTRACT:
The present invention relates to a replaceable sight gauge system to monitor fluid levels in a reservoir or fluid tank. The sight gauge of the present system is mounted to the wall of a fluid tank by two bolt assemblies. The bolt assemblies, which include an entry bolt, an exit bolt, and a fastener, are designed to selectively allow fluid from the tank to flow through the bolt assembly into the sight gauge while holding the sight gauge securely against the fluid tank. The entry bolt houses a valve which opens when the exit bolt is mated with the entry bolt. When the exit bolt is disengaged from the entry bolt, the valve moves back to a closed position so that fluid cannot escape from the fluid tank. The sight gauge can easily be replaced from the disengaged exit bolt.
