1. Specifications
1.1. Important information
- Carefully study and observe all items of these operating instructions
before commissioning the unit.
- In principle, the Wöhler UL 23 and US 23 Ultrasonic Leak Detection
should only be used by skilled personnel for its intended purpose and
within the specified range of data. Any liability or warranty for results
established or for defects caused when using the unit is excluded by all
means.
- Be careful, and use common sense around electrical currents! Use the
plastic waveguide, and keep at a safe distance!
- Warning: Ultrasonic detectors will not indicate a leak if there is no tur-
bulent flow producing sound when you check it. If you suspect a toxic
gas, natural gas or other combustible gas leak, and do not detect it with
the UL 23, do not assume that it does not exist as it may be turbulent.
Use another method as verification that there is no leaking gas present.
1.2. Application
The UL 23 Ultrasonic Leak Detection is a non-invasive leak detector that is
capable of detecting both pressure and vacuum leaks at e.g.:
- gas conduits
- supplies of portable water
- refrigerating sets of air conditioning installations
- LNG-tankers
- pneumatic systems
- hydraulic systems
- vacuum systems
- electrical systems: switches, relays and other contacts
The Ultrasonic sound generator US 23 is used to detect leaks in enclosures
which are not under pressure. It is ideal for the leak detection at
- buildings: doors, windows and other leakages (support of the leak detec-
tion with the BlowerCheck BC 21)
- automotives: panes, doors etc
- containers
- freezers
