n pi: corrosionmonitoring devices that transmit ultrasonic waves through production structures to locate discontinuities in metal structure, which indicate corrosion damage.

n: Schlumburger wireline tool that uses a single rotating ulrtasonic sensor to provide a complete image of the casing ,cement,and annulus .Can show casing damage/corrosion ,cement quality and channeling.

n: flowmeter used (1) to measure transit times of an acoustic pressure wave with and against the flow (time- of-flight-type meter) to infer pipeline velocity or (2) to reflect sonic energy from scatterers in fluid back to a receiver (Doppler-type meter) to measure volumetric flow rate.

a process using ultraviolet (UV) light to kill bacteria and viruses.
