Description
The VAPOPHONE is used to detect steam leakage in steam
systems in order to prevent live steam loss. It is particularly
suitable for monitoring steam traps and stop valves.
Live steam leakage is detected by sound in the ultrasonic
range caused by flowing steam. The mechanical ultrasonic
vibrations are detected by the sound probe of the VAPOPHONE
and converted into electric signals which are amplified in the
measuring instrument and indicated on a meter.
Owing to mechanical and electronic filtering, the VAPOPHONE
is most sensitive at frequencies between 40 to 60 kHz. As
long as the steam trap operates correctly or the stop valve
is closed tight the pointer on the meter will be close to zero.
When steam loss occurs the pointer deflects in proportion
to the steam leakage.
The VAPOPHONE is unaffected by ambient noise in the
audible range. The power supply is provided by an integral
rechargeable battery.
