ABSTRACT:
A liquid level gage system is disclosed. This system includes a displacer secured to a cable and movable in response to winding or unwinding said cable around or from around a rotatable drum. The rotatable drum is coupled to a driven shaft, and a drive assembly is provided to drive the driven shaft. An indicator subsystem is included which provides an indication of a change in the apparent weight of the displacer as the displacer is moved across a liquid level. A strain gage is a key component of the indicator subsystem. In one embodiment, an assembly is provided for powering the indicator subsystem and transferring data from the indicator subsystem which involves two pair of coils. In another embodiment, the gage system can be effectively remotely programmed using light signals.
