Abstract: Examples of determining tuberculation in a fluid distribution system are disclosed. In one example implementation according to aspects of the present disclosure, an acoustical wave generator generates an acoustical wave within a fluid path of a fluid distribution system. A first acoustical sensor and a second acoustical sensor sense the acoustical wave. An acoustical signal analysis module determines an amount of tuberculation within the fluid distribution system by analyzing the sensed acoustical wave.

Abstract: A leak detection sensor includes a transducer, the transducer including a base, a piezoelectric layer, and a conductive layer and at least two leads connected to the transducer. A method of making a leak detection sensor includes obtaining a transducer, the transducer including a base, a piezoelectric layer, and a conductive layer; and effecting a mounting hole such that the mounting hole is defined in the transducer. A jig includes a support and a punch.
