Performance Target Verification Kit
PTV-01

The PTV-01 provides an accurate method to test both
functionality and performance of the Incus ultrasonic
gas detectors.
The Incus is an omni-directional airborne leak detector that
responds to pressurised gas leaks. These detectors complement
traditional gas detection methods used in refineries, gas plants
and offshore installations.
Ultrasonic gas detectors are the only type of hazard (fire or gas)
detection product where the performance target set out in the
installation safety case can be verified meaningfully and safely.
The PTV-01 generates a "burst release" which represents the
ultrasound expected in the event of an incident. No more
than four tests should be needed to verify the total detection
envelope.

Operation
The PTV-01 is set up in direct vicinity of the potential gas leak
source, for example, next to a vunerable gas value. The pressure
in the release volume of the PTV is set to the same pressure as
would be typically found in the value. An orifice of the required
release hole size is fitted into the release nozzle of the PTV-01.
The size of the orifice will have been determined by the gas leak
size the client is looking for.
Once all is set up a volume of pressurized gas is released
through the PTV-01 orifice and the initial "burst" ultrasound is
generated .This is be detected by the Incus in the vicinity of the
value generated.
Through this test it is confirmed that the UGLD’s in the area will
detect and alarm at or below minimum required gas leak rate.
Only the inital "burst" is measured as by necessity the PTV-01
only contains a small volume of gas, unlike a process pipe.
Note:
When shipping gas cylinders, please ensure local regulations are
adhered to.
