Patent ID: 8726745

Claim:
A device, comprising: a plurality of sampling probes configured to sample a fluid; an ultrasound sensor coupled to the plurality of sampling probes, the ultrasound sensor configured to be moveable and to be used with each of the plurality of sampling probes, the ultrasound sensor further configured to: transmit and receive ultrasound energy; generate a first signal by receiving ultrasound energy reflected from a fluid surface of the fluid; and generate a second signal by detecting ultrasound energy reflected from a first surface configured to receive a fluid container comprising the fluid; and a controller electrically coupled to the ultrasound sensor and the plurality of sampling probes, the controller configured to receive the first signal and the second signal from the ultrasound sensor, and further configured to provide a control signal to each of the plurality of sampling probes to control a distance each of the plurality of sampling probes is lowered into the fluid based on the first signal, the second signal and a selected fluid volume to be sampled.
