Dispensing systems with wave sensors

摘要

A dispensing system (10) including:•a conduit (14) having a volumetric capacity between an internal discharge orifice (30) for receipt of a flow of pressurized fluid from a valving assembly and an external discharge orifice (32),•a volume of pressurized fluid and•a sensor (22) the fluid having 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 and the sensor (22) detecting a sound at the external discharge orifice.
