Ultrasound Applications

Common Uses of Airborne and Structureborne Ultrasound Technology

Valves
Valve activity such as leakage or blockage can
be accurately checked while the valve is on line.
Properly seated valves are relatively quiet while
leaking valves produce a turbulent flow as the
fluid moves from the high pressure side through
the leak to the low pressure side. Due to a wide
sensitivity and ultrasonic frequency selection
range, all types of valves even in noisy
environments can be accurately tested.

Valve Stems
Valve stems may be quickly tested for leaks to
atmos­phere.

Pressure/Vacuum Leaks
As any gas (air, oxygen, nitrogen, etc.) passes
through a leak orifice, it generates a turbulent flow
with detectable high frequency components. By
scanning the test area with an Ultraprobe, a leak can
be heard through the headset as a rushing sound or
noted on the display/meter. The closer the instrument
is to the leak, the louder the rushing sound and
the higher the reading. Should ambient noise be a
problem, a rubber focusing probe may be used to
narrow the instrument’s reception field and to shield
it from conflicting ultrasounds. In addition, Frequency
Tuning (available in most models) dramatically
reduces background noise interference to provide
ease of ultrasonic leak detection as never
before experienced.

Steam Trap Inspection
Major steam trap manufacturers have recommended ultra­ ound ins
spection of steam traps as one of the most reliable methods available.
By converting the ultrasonic elements of a working steam trap into the
audible range, Ultraprobe® allows users to hear through headphones
and see on a display/ meter the exact condition of a steam trap while
it is on line. Blow-by, machine gunning, oversized traps or line blockage are all easily detected. Frequency tuning enhances Ultraprobe’s
ability to discriminate be­ween condensate and steam. Ultraprobe®
t
markedly reduces confusion from extraneous sounds or from heat
transfer, even when traps are extremely close together.
