Marine Level transmitter

Marine Level Transmitter – Precision Tank Monitoring for Ballast, Fuel & Draft Systems

Product Overview
The Marine Level Transmitter is an advanced pressure-based measurement instrument engineered for continuous liquid level monitoring in critical marine applications. Utilizing a robust ceramic diaphragm and SUS316L construction, this transmitter delivers exceptional accuracy (±0.5% F.S.) for ballast tanks, fuel oil tanks, and draft measurement systems. With intrinsic safety certification (Exia II C T6) and IP68 submersible protection, it ensures reliable performance in the most demanding marine environments while providing precise 4-20mA output signals for remote monitoring and control systems.

Operating Principle
The pressure-type level transmitter operates by sensing hydrostatic pressure changes at the tank bottom corresponding to liquid level variations. This sophisticated system consists of a primary transmitter and signal amplifier that converts level height into proportional 4-20mA DC signals. The ceramic diaphragm ensures precise pressure measurement while the 2-wire configuration simplifies installation and integration with vessel monitoring systems, level indicators, and loading computers.
