An automated liquid reagent dispensing system

摘要

An automated liquid reagent dispensing system designed to accurately dose a fluid storage vessel 10 used by an internal combustion engine. Computer12A with installed software programs is activated by a trigger event caused by an independent filler cap sensor 2 and uses fluid level sensor 9 to measure an increase in level in the fluid storage vessel 10 to accurately calculate the required dose and deliver it by pump 11B from reagent reservoir11C. The reagent reservoir contains a level switch 11D that will trigger a low level alarm that is communicated to an operator via wireless technology 12D. The reagent dispensing system may be powered by an AC or DC electric power source 8 through the power controller 12B. Moisture sensitive components may be contained in a single (AA to CC) or in multiple (AA to BB & BB to CC) water and dust proof housings.
