A method for operating an ultrasonic measurement device, the ultrasonic measurement device comprising a first ultrasonic transducer and a second ultrasonic transducer, the method comprising: (a) driving the first and the second ultrasonic transducers (102a, 102b) at a driving frequency such that the first and the second ultrasonic transducers (102a, 102b) generate a first ultrasonic signal and a second ultrasonic signal respectively, (b) sensing the second ultrasonic signal at the first ultrasonic transducer to produce a first measurement signal and sensing the first ultrasonic signal at the second ultrasonic transducer to produce a second measurement signal, characterized by: (c) identifying a first set of data points in the first measurement signal and a second set of data points in the second measurement signal, wherein each data point in the first set of data points uniquely corresponds to a data point in the second set of data points, (d) generating a time-difference data series which corresponds to the driving frequency based on successively determining a time difference between time instants corresponding to each data point in the first set of data points and a corresponding data point in the second set of data points, (e) performing one or more statistical operations based on the time-difference data series, wherein steps (a) through (e) are performed for at least one driving frequency in a set of driving frequencies suitable for driving the first and the second ultrasonic transducers (102a, 102b), and (f) configuring an operating frequency suitable for driving the first and the second ultrasonic transducers (102a, 102b) based on the one or more statistical operations based on the time-difference data series corresponding to the at least one driving frequency.
