FBLT FBLT with NPT option
The Series FBLT Flush Tip Submersible Level Transmitters measure the height
of liquid above the position in the tank referenced to atmospheric pressure. The
transmitter consists of a piezoresistive sensing element, encased in a narrow 316 SS
housing with PTFE coated ush diaphragm tip.
BENEFITS/FEATURES
• Long operating life with a non-clog ush diaphragm tip for harsh applications
• Eliminates particulate or water droplets from entering the transducer using
maintenance-free lter
• Suits harsh environments with choice of polyether polyurethane or ETFE cable
materials for excellent chemical compatibility
• Increased life with lightning and surge protection utilizing dual arrestor technology,
grounded to case, eliminating both power supply surges and lightning ground strike
transients (surge protection is not guaranteed and is not covered by warranty)
• Meet application requirements with narrow body design allows the FBLT to t into
stilling wells and narrow installations
• Unit holds up in aggressive uids with robust FKM uoroelastomer diaphragm that is
PTFE coated for a stick-resistant surface
• Avoid product leaks typically cause by oil or grease with diaphragm cavity that is
lled with gel
• Flexible installation options with NPT connection to rigidly install in a pipe/conduit or
use the A-625 hanging loop to attach a chain to remove from the installation
APPLICATIONS
• Sewage lift stations
• Industrial slurries
• Industrial sumps
• Landll leachate
• Reservoirs
• Sludge pits
• Oil tanks
