What is it? Heartbeat Technology provides continuous or on-demand diagnostics, monitoring and verification to ensure your flowmeter is functioning correctly, independent of process and ambient conditions. This unparalleled self-monitoring capability offers complete flexibility to plan proof-testing and other maintenance with minimal effort and exposure of personnel. Heartbeat Technology is easy to use and can be activated at the touch of a button without interrupting the process. It’s accessible via the local display, the web server or system integration interfaces, thus needing no on-site presence. Seamless and traceable verification results are permanently stored and can be retrieved at any time. The reliability of your measurement is ensured in three ways: 1. Diagnostics Diagnostics is based on the continuous testing of a device’s health during ongoing operation. You are immediately warned if the device has reached a critical condition, enabling you to take quick and appropriate action. These How does it work? The diagnostic test functionality is embedded in the electronic modules, in the form of an internal reference system. This means the traditional method of verification with traceable, external measuring instruments is no longer necessary. Often the intervals between labour-intensive recalibrations can be extended. There is also the option to integrate the process into a higher-level control system or asset management system. All of this saves time and costs, while virtually eliminating the possibility of interference due to incorrect handling. For more information on Hearbeat Technology visit, www.au.endress.com/flow messages are interpreted in accordance with NAMUR NE 107 and are displayed by the device as a diagnostic event. This also includes direct instructions on what to do next, ensuring that the process can be up and running again quickly in the case of a shutdown to prevent unnecessary maintenance measures. 2. Monitoring Condition monitoring is recommended for applications with demanding operating conditions or where the device is subject to wear, for example from corrosion or abrasion. Condition monitoring recognises if the measuring performance or the integrity of the device is impaired. It also recognises trends in the secondary measured values and can evaluate the relationships between individual parameters, reducing the risks of an unexpected failure. Condition monitoring also makes it possible to display temporary, process-specific faults that neither calibration nor verification can detect, since they only take a snapshot of the device status. 3. Verification Verification can be used to take an immediate snapshot of the device status, to demonstrate that the flowmeter meets specific technical requirements. A verification report can then be produced, including a qualitative assessment of the checked parameters. It can be implemented either as quality documentation (for compliance with ISO 9001) or, in safety-related applications, as documentation of the proof test (for functional safety – SIL).
