1. A sensing module for assessing pipeline condition, comprising:
a body; and
one or more phased array ultrasonic transducers (PAUTs) assembled on a surface of the body, each PAUT configured to emit multi-channel ultrasonic waves for scanning a pipe wall, wherein at least one of the one or more PAUTs comprises:
a matching layer;
a backing layer;
a sensor placed between the matching layer and the backing layer for generating the multi-channel ultrasonic waves; and
a housing that receives the matching layer, the backing layer and the sensor therein such that the matching layer does not extend on an outside surface of the housing.
