Products
The MMC Sonic Tape is a portable, intrinsically safe tank gauging device that uses an advanced ultrasonic probe to deliver highly accurate ullage, interface, and temperature readings. Designed for use with vapor locks, it enables closed and restricted gauging operations—reducing vapor emissions and enhancing deck safety. Certified for explosive atmospheres (Ex ia IIB T4) and compliant with U.S. Coast Guard regulations, the Sonic Tape provides precise, direct tank level measurement without the uncertainties of traditional sounding tape methods, making it ideal for petroleum and chemical cargo tanks.
The MMC Closed Cargo Liquid Sampling Device is a portable closed tank sampling system designed for safe and accurate sampling of petroleum and chemical cargo on marine tankers. It connects directly to the MMC Tank Gauging Station (Vapor Lock Valve) installed on the tank top, allowing operators to collect liquid samples from different levels inside the tank without releasing hazardous vapors. This closed sampling design improves crew safety, environmental protection, and compliance with marine cargo handling regulations.
The Sonic Tape is a portable, high-accuracy tank gauging device that uses an advanced ultrasonic probe to detect liquid levels directly. Designed to overcome challenges such as temperature fluctuations and water accumulation in crude oil tanks, it provides fast, precise level readings without relying on residue-based measurements. Ideal for accurate cargo volume gauging, the Sonic Tape offers reliable performance as a direct gauging device for petroleum and chemical tanks.
Inert Gas Pressure Meter
The MMC Inert Gas Pressure Meter is a portable, gas-tight device designed to monitor inert gas pressure in cargo tanks during Crude Oil Washing (C.O.W.) operations. Easily connected to MMC Vapor Lock Stations, it provides real-time pressure readings from -10 kPa to +30 kPa, ensuring compliance with IMO regulations. Featuring a built-in screw-type orifice for controlled pressure changes and a mesh filter to prevent dust ingress, this meter delivers accurate, stable, and safe monitoring of tank atmosphere conditions.
SD-2W Sampling and Bottom Dryness Device
This integrated tank gauging and safety system is engineered to meet strict international maritime standards for safe and accurate cargo handling on oil tankers. Combining functions such as ullage measurement, temperature monitoring, oil-water interface detection, and vapor concentration checks, it ensures reliable, compliant performance in demanding marine environments. Designed for use with tank-top vapor locks, the system supports key regulations including SOLAS, MARPOL, and ISGOTT, making it a trusted solution for modern tanker operations.
