Dwyer SERIES FBLT FLUSH TIP SUBMERSIBLE LEVEL TRANSMITTER

Description

Dwyer SERIES FBLT FLUSH TIP SUBMERSIBLE LEVEL TRANSMITTER

Perfect for Sludge and Slurries, Lightning Protected, ±0.25% Accuracy
The Series FBLT Submersible Level Transmitter is designed with a flush diaphragm tip that will not clog in harsh applications such as sewage lift stations. Narrow body design allows the FBLT to fit into stilling wells and narrow installations. The FBLT features a robust FKM fluoroelastomer diaphragm that is PTFE coated for a stick resistant surface that will hold up in aggressive fluids. The diaphragm cavity is filled with a gel that will not leak out versus oil or grease that our competitors use. Body is constructed of 316 SS and the cable is either polyurethane or ETFE for more corrosive applications.

The unit measures the height of liquid above the position that it is mounted in a tank or pit in reference to atmospheric pressure. Ventilation tube in the cable automatically compensates for changes in atmospheric pressure above the fluid. The vent is protected with a maintenance free filter, eliminating particulate or water droplets from entering the transmitter. For extra protection against humidity, we offer the A-297 desiccant filter that can be attached to the vent tube.

The FBLT incorporates lighting and surge protection (not guaranteed or covered by warrantee) to stand up in harsh applications. Optional NPT connection allows the unit to be rigidly installed in a pipe/conduit, or to attach our A-625 hanging loop for attaching a chain for pulling out of the installation.

Features:

• Long operating life with a non-clog flush diaphragm tip for harsh applications
• Eliminates particulate or water droplets from entering the transducer using maintenance-free filter
• 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 fit into stilling wells and narrow installations
• Unit holds up in aggressive fluids with robust FKM fluoroelastomer diaphragm that is PTFE coated for a stick-resistant surface
• Avoid product leaks typically cause by oil or grease with diaphragm cavity that is filled 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
