1. A dispensing system, comprising:
- a conduit with a volumetric capacity between an internal discharge orifice for receipt of a flow of pressurized fluid from a valving assembly and an external discharge orifice;
a volume of pressurized fluid; and
a sensor,wherein the fluid has a volumetric flow rate of about 0.05 ml/ms to about 15 ml/ms when released into the conduit from the internal discharge orifice, andwherein the sensor detects a sound at the external discharge orifice.

Abstract
A dispensing system includes a conduit having a volumetric capacity between an internal discharge orifice for receipt of a flow of pressurized fluid from a valving assembly and an external discharge orifice. The dispensing system further includes a volume of pressurized fluid and a sensor. The fluid has a volumetric flow rate of about 0.05 ml/ms to about 15 ml/ms when released into the conduit from the internal discharge orifice. The sensor detects a sound at the external discharge orifice.

18. A method of dispensing, comprising the steps of:
-
detecting a sound emitted from a reservoir of fluid having a conduit; and processing the detected sound to determine at least one of (a) whether the container is full or empty;
(b) whether the container needs to be replaced;
(c) whether the container is authorized for use;
or (d) what operational parameter to initiate. - View Dependent Claims (19, 20)
