Yokogawa Rotamass Total Insight Coriolis Mass Flow and Density Meter

Advanced Coriolis Measurement Principle

Operating on the proven Coriolis force principle, the Rotamass Total Insight directly measures mass flow, actual fluid density, and process temperature in a single device. Because these measurements are independent of flow profile, viscosity, or Reynolds number, the meter delivers outstanding accuracy and repeatability for complex liquids, gases, emulsions, and suspensions.

Flexible Mechanical Design and Superior Installation

The series offers multiple sensor family designs—including Nano, Supreme, Prime, Intense, Hygienic, and Giga—to match exact spatial and operational constraints. It supports horizontal, vertical, and inclined installation orientations, with automatic compensation for density measurements when installed vertically or horizontally. Built-in features like robust enclosures (IP66/IP67) and microSD card parameter storage ensure maximum uptime and straightforward transmitter replacement without data loss.

Versatile Communication and I/O Flexibility

Designed for modern control architectures, the transmitter provides up to four configurable input/output channels supporting various communication protocols, including HART, Modbus, PROFIBUS PA, and FOUNDATION Fieldbus. All circuits are galvanically isolated to protect against electrical noise and ground loops, ensuring robust signal integrity in harsh plant environments.

Safe Local Operation and Maintenance

Operators can configure and monitor the device locally without opening the housing cover, using high-visibility dot-matrix displays equipped with responsive infrared (IR) optical buttons. Furthermore, dual-level security (software passwords and hardware write-protection DIP switches) prevents unauthorized parameter modifications, while advanced diagnostic tools support total health monitoring.

FAQ

• Q: Can I operate the display menu without opening the transmitter housing?

  A: Yes, the transmitter features responsive infrared (IR) optical buttons located beneath the display glass, allowing safe operation and parameter changes without removing the cover.

• Q: What is stored on the internal MicroSD card?

  A: The MicroSD card securely stores the complete product documentation, system-relevant parameters, sensor calibration constants (such as SK20, KD, FL20), and customer-specific configurations for easy transmitter replacement.

• Q: How is hardware write-protection enabled on the transmitter?

  A: Hardware write-protection can be activated by setting the internal DIP switch (SW1-2) on the main board behind the display to the high position, which prevents any unauthorized parameter modifications.

• Q: Are straight pipe runs required upstream and downstream of the flow meter?

  A: No, Coriolis mass flow meters do not require straight inlet or outlet pipe runs, making them highly versatile for tight installation spaces.
