Product Description


SN2-TQZ is a device installed at prescribed intervals on pipelines to detect the passage of a pig or sphere. The indicators function by extending a bi-directional trigger system or multi -directional(every angle) or Uni-directional Trigger System into pipelines through a Flange Fitting. When a pig passes an indicator, the trigger is tripped which immediately activates a Signaling systems. 

Signaling systems available with the SN2-TQZ include a flag indicator, a flag/electrical Switch Output or an electrical clock.


SN2-TQZ passage indicators are built to withstand the most brutal offshore/onshore environments. Each SN2-TQZ indicator is weatherproof and corrosion-resistant. All components exposed to pipeline products are completely sealed to prevent leakage.Components exposed to the atmosphere are 316(or 304) stainless steel except the switch block (on electrical models) which is aluminum alloy or 316SS with protective powder coating. Plug assembly is bidirectional or multi -directional,but the signaling systems is omni-directional, it can be  adjusted after it is set. This means the flag or electrical clock can be oriented to face any desired direction. The flag indicator offers high visibility.
