Assurance Factor®

Permanent monitoring for reliable flow measurements

 

 

 

Especially in industrial applications, the production process must be safe and stable to ensure high quality and efficiency. Accurate and reliable flow measurement plays a crucial role. With the Assurance Factor®, Rheonik has developed an advanced diagnostic function that allows continuous self-monitoring of the measurement system and early detection of potential problems. This real-time assessment of measurement integrity, built into the RHE 20 and RHE 40 transmitters, ensures that readings remain reliable and unexpected deviations are avoided.

 


Functionality of the Assurance Factor®

The Assurance Factor® employs an analytical approach to assess multiple key parameters within the measurement system. These parameters include Drive Gain and its Stability, which monitor the energy demand to maintain sensor oscillation, as well as Pick-up Signals and their Symmetry, which provide insights into the sensor's condition.Additionally, Frequency Stability ensures consistently precise measurements.The aggregate of these factors contributes to an overall value between 0 and 100, providing an immediate assessment of measurement quality. Values exceeding 50% are indicative of reliable measurement, while values below 50% suggest potential issues.
 

 

Continuous Monitoring with the Assurance Factor®

The Assurance Factor® is a comprehensive system that monitors critical parameters and identifies potential disturbances in mechanical, electrical, and electronic components. These disturbances may include electromechanical failures, such as loose screws or corrosion on cable connections, mechanical disturbances from nearby machine vibrations, and electrical interference from high-power equipment. The system also detects and evaluates issues with sensor and electronic components, such as anomalies in coils or pick-up signals. By continuously monitoring and identifying these disturbances, the Assurance Factor® ensures the smooth operation of the measurement process and safeguards against potential malfunctions.

 

Benefits of Assurance Factor®

Thanks to continuous self-diagnosis, the Assurance Factor® offers several advantages for industrial applications. It enables seamless real-time monitoring, enhances process security through early fault detection, and minimizes unplanned downtime. The precise diagnostic function ensures that maintenance actions can be initiated in a targeted and timely manner instead of reacting to unexpected failures. Furthermore, measurement quality assessment is directly visualized via the RHE transmitter interfaces or the RHEComPro software, allowing users to have a clear overview of their measurement system status at all times. Obviously, the status of the system is directly on the sensor display. The Assurance Factor value can be used to trigger changes in screen color when the display is fitted (White – Amber – Blue – Red), providing highly visible wide-area condition indication.

 

Maximum Security with Assurance Factor®

With Assurance Factor®, Rheonik ensures that industrial flow measurements remain reliable, precise, and transparent even under demanding conditions. By providing intelligent self-monitoring and instant availability of relevant diagnostic data, process control is optimized, and operational safety is maximized
