Intrusive

TDW’s PIG-SIG V Pig Passage Indicator is a device installed at prescribed intervals on pipelines to detect the passage of a pipeline pig. This unique product functions by extending an omnidirectional trigger into the pipeline through a welded fitting: the trigger is tripped by the passage of a pipeline pig. The TDW PIG-SIG V Pig Passage Indicator is easy to install, compatible with all standard THREAD-O-RING nipples, as well as flanged fittings, and all but eliminates trigger breakage. Signaling systems available with the PIG-SIG V device include a flag indicator, an electrical indicator or a combination flag/electrical unit. The PIG-SIG V device can also be provided in a flange-mounted configuration per the required pipeline pressure class (up to 2500 lbs).
