A measuring device for use with at least one measuring cup comprised of: a microprocessor, an ultrasonic transmitter, and an ultrasonic sensor, all positioned on a printed circuit board housing, all of which are contained within a housing, and a display screen on the housing. The transmitter emits a signal (e.g. an ultrasonic pulse that reflects off of the top surface of a liquid contained in the measuring cup,) and the ultrasonic sensor detects the reflected ultrasonic pulse. The microprocessor calculates the precise volume of liquid within the measuring cup and displays the volume on the display screen. The measuring device can alternately be programmed to emit an alert when a predetermined volume is reached. The measuring device and measuring cup unit can also be used with solids and/or slurries. |
