Abstract
A transducer positioning device and a system for employing a transducer positioning device are used to determine and monitor fluid levels in a pressurized beverage keg that has a dip tube. One fluid is a liquid beverage. The other fluid is a compressed gas injected to push the beverage up through the dip tube. Each embodiment of the positioning device generally includes an acoustic transducer and a transducer support, and often includes a base. Other embodiments may include an angled adapter for the transducer and a prop and/or wheels for the base. Each embodiment of the system generally includes the transducer positioning device, a transceiver, software, and a graphic user interface, as well as wiring and a medium for data transmission. Other embodiments include at least one other electronic controller. The above may also be embodied as kits and methods.
