Abstract
An ultrasonic system for measuring the volume of liquid in a container having a lid in which an ultrasonic signal is emitted and received by a sensor subsystem located on the underside of the lid of the ultrasonic system. The ultrasonic system can measure the exact amount of liquid or the level of the liquid held in the container by processing the roundtrip time the ultrasonic signals took to travel from the sensor subsystem to the surface of the liquid where the ultrasonic signals are reflected back to the ultrasonic sensor subsystem. A solid state, three-phase SCR/diode bridge converts a three-phase alternating current (AC) to a direct current (DC) power source for heating the liquid in a boiler subsystem prior to its transport to the container. A second, triac controlled heater is powered by a single phase of the three phase power source, and is used to warm and maintain the liquid held within the container at a constant temperature.
