Abstract
A postmix beverage dispenser valve including a fluidic oscillator flowmeter in conjunction with a master controller and a flow control valve such as a proportional solenoid. The frequency of the syrup oscillations in the fluidic oscillator is linearly related to the syrup velocity and thus to the volume flow rate. Various sensors can be used to detect the fluid oscillations with the preferred one being a piezo electric film transducer having a protective coating and used with a flex cavity in the conduit wall. A pressure compensation device can be used to isolate the solenoid armature from varying syrup pressures.
