Abstract: A system for monitoring sanitation agents in a laundry machine comprises a plurality of channels. Each channel has an input port, an output port, and a glass tube. Each input port and output port is adapted to be fluidly coupled to the laundry machine. The system includes a monitoring unit associated with each of the glass tubes. Each monitoring unit includes a bubble detector and a flow rate measurement unit. A beeper is configured to generate an indication of an alarm condition based on a determination made by any one of the monitoring units. The system has a display screen, a memory storing computer-readable instructions, and a controller communicatively coupled to each of the monitoring units. The controller is configured to execute the instructions to wirelessly communicate to a web page a volume of a sanitation agent that has passed through each of the glass tubes.
