6. A fluid line monitoring and control assembly comprising:
a valve configured to be insertable in-line with a conduit connecting a storage vessel to a dispensing tap, such that the valve is positioned proximate to the storage vessel, wherein the valve is configured for selectively closing the conduit for terminating flow of a beverage through the conduit, the valve comprising a solenoid valve;
a flow meter configured to be insertable in-line with the conduit, such that the flow meter is positioned proximate to the valve, the flow meter being configured for detecting at least one parameter indicative of each of a liquid state and a foam state of the beverage and for generating a first signal and a second signal, respectively, corresponding thereto, the second signal being of the same form as the first signal but differing in magnitude, stability, or frequency, the flow meter comprising a thermal mass flow meter, a mechanical flow meter, a pressure based flow meter, a variable area flow meter, an optical flow meter, a vortex flow meter, a sonar flow meter, an electromagnetic flow meter, an ultrasonic doppler flow meter, a Coriolas flow meter, or a laser doppler flow meter, the thermal mass flow meter comprising a microelectromechanical system sensor configured for thermopile sensing, the microelectromechanical system sensor being configured for measuring liquid flow rates of between 0.0 and 10.0 liters/minute;
a controller communicatively engaged to the valve and the flow meter, such that the controller is enabled for receiving the first signal and the second signal, the controller being programmed for converting the first signal to a volume of the beverage flowing through the conduit and for utilizing an algorithm to evaluate the first signal for a change in magnitude, stability, or frequency to determine if the beverage passing through the conduit has changed between the liquid state and the foam state, the controller comprising a transceiver, wherein the transceiver is configured for communicating wirelessly with an electronic device;
foam in line programming code positioned on the controller enabling the controller for selectively actuating the valve for closing the conduit upon receipt of the second signal, wherein the valve is configured for terminating flow of the beverage in the foam state past the valve;
a housing defining an interior space, the valve, the flow meter, and the controller being coupled to the housing and positioned in the interior space, the flow meter being fluidically engaged to the valve within the housing;
an inlet connector engaged to and extending from the housing, the inlet connector being engaged to the flow meter and being configured for engaging one of:
the conduit, such that the conduit is in fluidic communication with the flow meter,
an outlet of the storage vessel containing the beverage, such that the outlet is in fluidic communication with the flow meter, and
a probe of a keg tap engaged to the outlet, such that the probe is in fluidic communication with the flow meter, the inlet connector comprising a threaded connector, the threaded connector being complementary to the probe of the keg tap;
an outlet connector engaged to and extending from the housing, the outlet connector being engaged to the valve and being configured for engaging the conduit, such that the conduit is in fluidic communication with the valve, the outlet connector comprising a shank, the shank being threaded as is the probe;
an indicator operationally engaged to the controller, positioning the controller for actuating the indicator when the second signal is received; and
a switch operationally engaged to the controller, wherein the switch is configured for switching for signaling the controller for deactuating the indicator and for actuating the valve.
