Abstract
A method for sequentially monitoring a level of a sanitation agent comprises the step of providing a supply tube having a first portion and a second portion. The method includes the step of linking the supply tube first portion and the supply tube second portion with a pipe. An optical sensor is situated adjacent the pipe, and is used to take a reference reading and a fault check reading. A controller imposes a warning signal when a difference between the reference reading and the fault check reading is greater than a threshold. The reference reading is taken when the sanitation agent is in direct contact with the pipe.
