How Does Heartbeat Technology Simplify Flowmeter Verification?
In functional safety applications (such as the chemical and oil and gas industries), flowmeters must ensure the highest reliability. Proline flowmeters use Heartbeat Technology™ to provide the most comprehensive built-in diagnostics for the entire signal chain, with non-parallel self-monitoring capability, traceable factory calibration, and redundant internal references. This minimizes failure rates, gives you complete flexibility to schedule self-checks and maintenance as needed, and reduces personnel exposure.
Core Advantages of Proline Flowmeters
- Highest safety level and highest reliability: Proven in countless challenging applications, robust and durable.
- Compatibility testing based on traceable reference values: Ensures measurement accuracy remains trustworthy.
- Maximum flexibility in scheduling regular maintenance: Self-check according to operational needs, not for the sake of self-checking.
- Minimum personnel workload and exposure: Reduces on-site operational risks.
- Provides a basis for critical safety measurement points: Helps determine and verify safety conditions.
High Safety and High Reliability Design
In chemical and oil and gas operations, safety has the highest priority. Therefore, flowmeters in functional safety applications must ensure the highest reliability. Despite the high cost, regular verification testing at critical measurement points is an established method for verifying functional reliability. With Heartbeat Technology™, Proline flowmeters minimize workload and reduce personnel exposure in such activities from the perspective of plant operators.
High Reliability, Minimizing Failure Risk
Proven in countless challenging applications, Proline flowmeters have demonstrated robustness, durability, and high reliability. Strictly designed based on safety design principles, we can significantly reduce failure risk:
- Built-in diagnostic detection functions in electronic modules.
- In the factory, modules undergo 100% traceable testing.
- Certified calibration facilities use Proline series flowmeters as traceable reference values to achieve continuous self-monitoring.
Flexible Maintenance with Heartbeat Technology™
Functional safety standards, such as IEC 61508, use probability of failure on demand (PFD) as the basis for establishing regular verification test schedules. Because heartbeat diagnostics minimize PFD, Proline users can plan their maintenance with maximum flexibility compared to users of other flowmeters:
- You can plan self-checks based on operational needs
- Rather than self-checking for the sake of self-checking.
Compliant with Simple Electronic Reporting
Triggered on-site or remotely, Heartbeat verification is added to self-check validity - without interrupting the process. Perform a complete diagnostic test and store the results in secure digital flash memory inside the device. The last eight data sets are stored and can be collected via asset management tools to generate standard electronic documentation. With approximately 95% test coverage, Heartbeat Technology™ ensures the flowmeter operates within its specified measurement accuracy.
