FLD-SMC High-Performance Leak Detection Controller from Naftosense

FLD-SMC High-Performance Leak Detection Controller from Naftosense
FLD-SMC is a high-performance all in one monitoring controller built into one budget conscious package. It is designed for detecting leaks of refined petroleum products and solvents in extreme environmental conditions when installed with approved sensors FLD-HSC-TL and FLD-O2W-SP. The device is a wall-mounted standalone leak detection controller. The maximum sensor length is limited to 150-ft/45 m per FLD-SMC distributed in three separate zones. These leak detection controllers (FLD-SMC) offer industry-standard output communications:
  • Modbus RTU
  • Modbus TCP
  • Dry contacts (2 SPDT Relays)
For classified locations applications, the sensor cables and the sensor probe will be wired to the controller through a Zener barrier, with FLD-SMC module installed in an area approved enclosure.



FLD-SMC Leak Detection Controller Features

  • Detects leaks of combustible liquids in a very wide temperature ranges in under 30 seconds!
  • 10-Year Factory Warranty on Controls & sensors
  • Provides indication of the leak magnitude (LCD and Modbus versions only)
  • Able to detect the vapors from refined fuels
  • The only FM7745 approved leak detection controller with adjustable alarm threshold allowing you the most rapid alarm to leaks



FLD-SMC Leak Detection Controller Applications

  • Leak detection around generators, Subbase tanks, day tanks, and supply and return plumbing in Data Centers, Industrial Facilities, Hospitals and Commercial buildings
  • Detection of leaking fuel oil from boiler installations, Fuel oil storage, and supply and return plumbing
  • Fuel / Oil on water Leak detection in outdoor containment areas and sumps
