Series MBLT Miniature Submersible Level Transmitter
Only 0.63" (16 mm) in Diameter, Perfect for Wells and Boreholes, Up to ±0.10% Accuracy
The MBLT Miniature Submersible Level Transmitter is only 0.63" in diameter making it ideal for level monitoring in well and borehole applications. Constructed for years of trouble free service, the MBLT has a welded 316 SS body and 316 SS nose cap. Body top is also 316 SS and tapered to prevent damage or snares when pulling the unit out of the installation. Featured in the MBLT is a precision ±0.10% or ±0.25% of full scale accuracy output, better than BFSL or BSL rated outputs used by most competitors. Lightning and surge protection (not guaranteed or covered by standard warranty) is included standard to stand up in harsh applications. MBLT comes with a choice of polyether polyurethane or ETFE cable materials and all are vented for barometric pressure compensation. Vent is covered with a maintenance-free filter preventing particulate or water droplets from entering the transmitter.

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.
