Abstract
An apparatus for measuring porosity of a structure includes an ultrasonic transducer device configured to be pressed against a structure, the ultrasonic transducer device being further configured to emit ultrasonic pulses into the structure and detect echo profiles; and an electronic device including: a manager having an interface gate, a back-surface sensing gate and a back surface analysis gate; a pulse generator interfacing with the manager and the ultrasonic transducer device; a data acquisition device interfacing with the ultrasonic transducer device and the manager; and a display having a porosity indicator interfacing with the manager.
