Ultrasonic thickness testing with Arduino
i totally new arduino , i'd thoughts , advice on project i'm considering.
i have seen numerous projects building ultrasonic range finder arduino used time delay between initial ultrasonic pulse , sound being reflected object. in case of ultrasonic thickness gauges, ultrasonic pulse sent through transducer held in direct contact object being measured , time takes sound reflected transducer converted distance. it seems me real difference between ultrasonic range finder , thickness gauge type of transducer used.
thickness gauge transducers relatively cheap compared price of instrument (which can run thousands of dollars decent unit) , wondering if type of thing can done relatively inexpensive arduino. thickness gauge transducers operate on frequency of either 5 mhz or 7 mhz 5 mhz being popular. using measure thickness of steel plate , need resolution of 0.001". speed of sound in carbon steel 0.23 inch/µsecond , able measure need able time pulses between pulses precision of 0.002 µsecond. measurements typically taken 20 times per second.
is within capabilities of arduino? model suggest, , can provide feedback on feasibility of this? appreciate help!

i need able time pulses between pulses precision of 0.002 µsecond.
directly resolving 2 nanoseconds on device cycle time of 62.5 nanoseconds tough call.
an arduino might able control external hardware measurement, , provide means of displaying result, not make measurement itself.
