Overview
Overview and Theory of Operation
The INCON TS-LLD is an electronic line leak detector
system. It has two components: a Control Unit (or CU)
and a Leak Sensing Unit (or LSU). The CU is mounted in
the station near the pump control relay box, and the LSU is
installed in the line leak detector port at the submersible
pump housing. One system per pump is required to detect
leaks from a pressurized fuel line.
The TS-LLD detects leaks in the pipeline leading from the
submersible pump to the dispenser. To comply with
current EPA regulations, three types tests are provided.
These are: a 0.1 gph annual test, a 0.2 gph monthly test,
and a 3.0 gph hourly test, which run at full line pressure.
