Modular Measurement and Control

MMC (Modular Measurement and Control) Portable Tank Level Gauge, commonly known as a Ullage Tape Gauge or MMC TAPE.

📌 Purpose:

This device is used primarily on oil tankers and chemical carriers to measure:

• Ullage (the distance from the surface of the liquid to the top of the tank)

• Oil/chemical levels

• Temperature

• Water interface level

⚙️ Key Features:

• Digital or mechanical readout for accurate ullage or innage readings.

• Vapor-tight construction, suitable for use in hazardous environments (e.g., flammable cargo tanks).

• Sampling valve or thermowell may be integrated to take samples or measure temperature.

• Compatible with closed gauging systems, meeting SOLAS and ISGOTT safety standards.

🚢 Common Use on Ships:

• Measuring cargo levels in tanks without opening them to the atmosphere (ensuring safety and environmental compliance).

• Often required by classification societies and port authorities for cargo operations.
