Key Features & Benefits
High Accuracy & Stability: The resonant sensor technology provides industry-leading performance, minimizing measurement drift over time.

Robust Construction: Designed to withstand harsh process conditions, including high static pressure and wide temperature swings.

JIS Flange Standard: Directly compatible with piping and vessels using Japanese Industrial Standard flanges.

Easy Integration & Configuration: Standard 4-20mA HART output allows for easy connection to control systems, and configuration can be done via the local indicator (if equipped) or a HART communicator.

Comprehensive Diagnostics: Built-in diagnostics enhance plant safety and reduce maintenance time by providing early warnings of potential issues.
