Abstract

A fluid line monitoring and control assembly for detecting foaming and terminating flow in a beverage line includes a valve and a flow meter, which are insertable in-line with a conduit connecting a storage vessel to a dispensing tap, and a controller. The valve and the flow meter both are positioned proximate to the storage vessel. The valve can close the conduit to prevent flow of a beverage therethrough. The flow meter generates a voltage signal with flow of the beverage therethrough and sends the voltage signal to a controller. The controller is programmed with an algorithm that enables the controller to evaluate the voltage signal for a change in one or more of magnitude, stability, and frequency to determine if the beverage has changed between a liquid state and a foam state, whereupon the controller actuates the valve to close the beverage line.
