Dispensing system with material level detector

A method of determining a remaining service interval of a dispensing system reservoir, comprising:

• determining a first real time amount of fluid product in the dispensing system reservoir at a first time within a first period of time;
• determining a second real time amount of fluid product in the dispensing system reservoir at a second time within the first period of time;
• determining an average usage rate over the first period of time;
• determining a corrected average usage rate of the average usage rate to account for a difference between the first real time amount and the second real time amount;
• determining a remaining service interval for the dispensing system reservoir based upon the corrected average usage rate over the first period of time;
• and
• communicating, via a transceiver of a dispensing system, the remaining service interval to a computer.

A method of determining a remaining service interval of a dispensing system reservoir, comprising:

• determining an average usage rate for a dispensing system by monitoring a number of dispersions over a period of time;
• detecting a real time amount of fluid product in the dispensing system reservoir by detecting a first change from a first amount of fluid product in the dispensing system reservoir to a second amount of the fluid product in the dispensing system reservoir;
• determining the remaining service interval of the dispensing system reservoir based upon the average usage rate and the real time amount of the fluid product in the dispensing system reservoir;
• and
• communicating, via a transceiver of the dispensing system, the remaining service interval to a computer.
