SERIES MBLT MINIATURE SUBMERSIBLE LEVEL TRANSMITTER

SERIES MBLT MINIATURE SUBMERSIBLE LEVEL TRANSMITTER

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.

Product Applications

  • Sewage lift stations, industrial slurries, industrial sumps, landfill leachate (non-hazardous only), reservoirs, sludge pits, oil tanks, etc.

Questions

Question
Is it safe to soak an MBLT level transmitter in vinegar or muratic acid to remove accumulated scale deposits?
Answer
Feel free to use whatever cleaning chemicals you like to remove accumulated scale deposits as long as the chemicals are compatible with the unit’s wetted materials as specified in our published literature.
Question
Our client has an MBLT pressure transmitter that appears to be malfunctioning due to scale buildup. The transmitter is installed to measure leachate level in a one-year old municipal sanitary landfill. What can we use to remove scale from the transmitter without damaging the transmitter?
Answer
If the issue is due to build-up which consequently plugs the small sensing holes, you might take a look at our PBLT2 or FBLT series. They are both more rugged and designed for sludge and slurries, whereas the MBLT and SBLT2 are better suited for cleaner applications such as ground water and wells.
