Product Introduction

Modern vessels require continuous monitoring of:

• Cargo tanks
• Ballast tanks
• Fuel oil tanks
• Diesel oil tanks
• Fresh water tanks
• Sludge tanks
• Service tanks

The MAS 2600 Tank Contents Transmitter measures liquid levels and transmits accurate signals to the ship's automation and cargo management systems.

This allows officers and engineers to monitor tank conditions from centralized control stations instead of relying solely on manual sounding procedures.

What Is the EMERSON MAS 2600 Tank Contents Transmitter?

The MAS 2600 is an intelligent electronic transmitter designed to convert tank pressure and level information into digital measurement signals.

The transmitter continuously measures:

• Tank level
• Tank contents
• Liquid volume
• Hydrostatic pressure
• Tank status

These values are transmitted to the vessel's:

• IAS (Integrated Automation System)
• Cargo Control Room
• Engine Control Room
• Tank Monitoring Stations
• Loading Computers

How the MAS 2600 Works

The transmitter operates using hydrostatic pressure measurement principles.

Step 1

The sensor is installed at a predetermined location inside the tank.

Step 2

The liquid column creates pressure proportional to liquid height.

Step 3

The pressure sensing element detects this pressure.

Step 4

The electronic module converts pressure into digital level information.

Step 5

The signal is transmitted to the monitoring system.

Step 6

The operator views tank levels from control stations.
