Abstract
A post-mix beverage valve provides for automatic, accurate beverage ratioing. A valve body can be assembled, and includes a water flow hard body, syrup body and common nozzle body. The water and syrup flow bodies define flow channels and include one end for connection to water and syrup respectively, and opposite ends for fluid connection to the nozzle body. The water flow channel includes a turbine flow sensor connected to a micro-controller determining the water flow rate. The syrup flow channel includes a flow sensor, two MEMS pressure sensors, monitoring the syrup. The sensors are connected to the micro-controller and positioned about an orifice and senses sense a differential pressure indicative of syrup flow rate solenoid regulates flow of syrup through the syrup body. A stepper motor on the water body controls a rod in the flow channel in conjunction with a V-groove.
