MMC SONIC TAPE GAUGING DEVICE
MMC Closed Type Gas Tight TRIMODE UTI Gauging Tape





Description
The Closed Flexi-Dip™ (also known as a Universal Tank Interface or UTI Meter) is a battery-operated, intrinsically safe measurement device designed for use with vapor control valves on storage or cargo tanks. This device enables precise and secure closed-system gauging, effectively sealing the system to prevent the release of toxic vapors during cargo handling. The measuring tape is available in both Metric and English units, with an anti-static coating on both the tape and sensor to ensure safe operation.
The MMC Closed Type Gas Tight TRIMODE UTI Gauging Device is a versatile, high-precision instrument designed for marine applications, catering to the needs of professionals who require reliable cargo tank monitoring equipment and portable tank level measurement devices. Known for its integration with the MMC UTI Tape and MMC Sonic Tape models, this device supports triple-function gauging for temperature ullage interface and provides accurate measurements in various tank environments. Equipped with MMC vapor locks and gas-tight sealing, this cargo tank gauging instrument ensures safety and compliance, preventing vapor leaks during operation. With its oil-water interface detector, it offers precise liquid level detection, making it a go-to device for marine suppliers of MMC and sampling equipment sellers. Popular in regions like Asia and Japan, the TRIMODE UTI device is available through MMC Sonic Tape Dealers and can be found under models such as the MMC Tape Model D2401.
Key Features
Closed Gauging System: Once inserted into the vapor control valve, the system remains closed, maintaining a seal and complying with global regulatory standards as a fixed gauging equivalent for the duration of cargo operations.
User-Friendly Tape Design: The tape includes markings to indicate direction, motion, and full rewind position, facilitating ease of use and accuracy in fluid level measurement.
Grounding Safety: Comes with a coiled grounding cable and a large alligator clip for safe grounding as standard equipment.
