Abstract:
A calibration system for a pulsed phase-lock loop ultrasound measurement system comprising an apparatus having a compartment for holding a pressure sensitive liquid. The compartment has an opening by which a flow of the pressure sensitive liquid may be controlled. A sensor arranged relative to the compartment to receive ultrasonic signals that reflect off one or more inner surfaces of the compartment. The system includes a processing device for receiving an integrated error signal output by the sensor based on pressure changes of the pressure sensitive liquid responsive to a change in flow of pressure sensitive liquid between the source and the compartment.
