SERIES MBLT | MERCOID® BY DWYER

MINIATURE SUBMERSIBLE LEVEL TRANSMITTER

Only 0.63˝ (16 mm) in Diameter, Perfect for Wells and Boreholes, Low Power Models for Telemetry Systems

LEVEL

The Series MBLT Miniature Submersible Level Transmitter measures 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 0.63˝ (16 mm)

diameter 316 SS housing.

FEATURES/BENEFITS

• Slender 0.63˝ (16 mm) diameter design ts in narrow openings

• Constructed for years of trouble free service with welded 316 SS body and 316 SS nose cap

• Body top is 316 SS and tapered to prevent damage or snares when pulling the unit out of the installation

• ±0.10% or ±0.25% FS accuracy output is more precise than BFSL or BSL rated outputs used by most competitors

• Maintenance free lter eliminates particulate or water droplets from entering the

transducer

• Comes with a choice of polyether polyurethane or ETFE cable materials for excellent chemical compatibility

• Incorporates lightning and surge protection, eliminating both power supply surges and lightning ground strike transients (surge protection is not guaranteed and is not covered by warranty)

APPLICATIONS

• Ballast tanks

• Ground water monitoring

• Surface water monitoring

• Dewatering

• Down hole

• Remote telemetry

• Remote ood monitoring

• Narrow conduit or pipe installations

• Remediation and environmental monitoring
