Mercoid Series MBLT

Miniature Submersible Level Transmitter — Only 0.63″ Diameter

Mercoid Series MBLT Miniature Submersible Level Transmitter

Only 0.63″ Diameter • Up to ±0.10% Accuracy • 8V Power Options

The Mercoid Series 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. The 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 is included standard. Low power voltage models are available for battery-powered applications.
