An apparatus and method of sensing fluid level in reservoir for calculating fluid flow there from. The method comprising the steps of: receiving a plurality of fluid level signals each indicative of respective fluid level state at a predetermined location within the reservoir; identifying change of a first fluid level state; recording a relative first time, with respect to fluid flow duration, at which the first fluid level state changed; and calculating fluid dispensed from the reservoir using the fluid flow duration and an average fluid flow rate associated with the respective fluid level location within the reservoir. The apparatus comprising: a plurality of fluid level probe elements located within the reservoir, each adapted to provide a respective fluid level signal; and a processor module adapted to receive receiving a plurality of fluid level signals. |
