    摘要： A liquid level gage system (10) is disclosed. This system includes a displacer (12) secured to a cable (14) and movable in response to winding or unwinding said cable around or from around a rotatable drum (16). The rotatable drum (16) is coupled to a driven shaft (20) and a drive assembly (28,74) 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 (54,56) 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 (82,84,88,90). In another embodiment, the gage system can be effectively remotely programmed using light signals (106,108).
