Abstract
Apparatus for monitoring the height of the liquid in a liquid-containing tank equipped with a height gage including an adjusting disc coupled to the gage shaft, an increment wheel coupled to the adjusting disc and being rotatable in response to rotation of the gage shaft, and a coupling member secured to the increment wheel and the shaft of an encoder assembly. The coupling member is effective to transmit liquid height information from the increment wheel to the encoder assembly. Methods for calibrating such apparatus are provided.
Claims20
An apparatus for monitoring the height of the liquid in a liquid-containing tank equipped with a height gage including a gage shaft rotatable in response to changes in the height of the liquid in the tank, said apparatus comprising:
- an adjusting disc directly coupled to the gage shaft and being rotatable in response to rotation of the gage shaft;
- an increment wheel coupled to said adjusting disc and being rotatable with said adjusting disc, said increment wheel being effective to give a visual indication of the height of the liquid in the tank;
- and
- a coupling member secured directly to said increment wheel and secured to the encoder shaft of an encoder assembly adapted to provide signals indicative of the height of liquid in the liquid-containing tank, said coupling member being configured to rotate the encoder shaft in response to rotation of said increment wheel.
