Introduction
The Rheonik RHE 45 Coriolis Mass Flow Transmitter – Integral / Compact Mount is an ultra-compact, high-performance Coriolis transmitter engineered for precise and reliable multi-parameter measurement in demanding industrial environments. Designed with Rheonik’s advanced signal processing technology, it delivers exceptional accuracy in mass flow, density, and temperature measurement while maintaining robust performance under varying process conditions. Its integral/compact mounting configuration enables space-efficient installation directly at the measurement point, minimizing cabling requirements and reducing signal losses. Leveraging Rheonik’s AnyInterface Commitment, this model ensures seamless integration with a wide range of control architectures, PLCs, and SCADA systems through extensive communication protocol support. The transmitter is optimized for real-time data acquisition, process control, and diagnostics, offering high-speed outputs and flexible I/O configurations to meet complex application requirements. Optional visualization via a backlit color LCD enhances on-site operability, while the Rheonik Assurance Factor provides continuous validation of measurement integrity, ensuring long-term reliability and process confidence.
