Valve leak detector
Squeak™ 5132 Physical Acoustics

Designed for operations and maintenance
personnel to perform frequent valve checks
in their units, Valve-Squeak is an easy-to-use
through-valve loss detection system. Small
enough to fit in your pocket, Valve-Squeak
isolates leaks of any size and in any valve saving
you thousands, if not millions of dollars.

Simple Operation. A green light shows a "no
leak" and a yellow LED bar graph shows a leak
range of "small" to "very large". Once a leak
is identified, your VPAC™ unit can be used for
quantification. Valve-Squeak has high noise
and vibration immunity and is Intrinsically Safe
for use in hazardous, gaseous environments
that require Class I, Div 1, IIC, T4 (currently only
meeting US certifications).
* The valve leak still needs to be verified and
quantified by a VPAC system and operator.
* To keep the Valve-Squeak cost low, it contains
simplified electronics.
* With the low cost of the Valve-Squeak it's
possible to have many units in a refinery or
plant to help the single VPAC operator locate
potential loss.
* VPAC operators are still needed to quantify/
measure CFM or GPM
