Abstract
A liquid level monitoring and transmission system includes a mechanical assembly in communication with the liquid in a container and a dual electronic encoder assembly in communication with the mechanical assembly for determining liquid level. The dual electronic encoder assembly includes a first encoder for encoding data indicative of fine level measurements and a second encoder for encoding data indicative of coarse level measurements. The system further includes at least one processor for controlling operation of the first and second encoders and for processing encoded data therefrom and a power control system.
