Tested and independently certified by TÜV, Heartbeat Verification fulfils all requirements specified by DIN EN ISO3 and can be used interchangeably with traditional wet calibration for traceable instrument checks. Reliability is increased, and uncertainties between calibrations are significantly reduced. In contrast to wet calibration, Heartbeat Verification does not use a primary fluid but relies on redundant internal references to verify the device functionality.

Our expertise in the field

A baseline of values is established during the original factory calibration and permanently stored both in the non-volatile, secure memory of the flowmeter, and on file at the factory. When Heartbeat Verification is performed on site the test data is compared with this baseline to detect any electronic component drift or mechanical deterioration of the instrument. Critical electronic circuits are implemented redundantly allowing the detection of hardware failures.

• In comparison to wet calibration, integrated verification functions in measuring devices such as Promass 100/300/500 Coriolis flowmeters lead to a time saving of at least 80% and extended calibration cycles.

Instruments with Heartbeat Technology deliver consistent and reliable measuring values for years and years of operation. Calibration frequency can in many cases be significantly reduced without jeopardizing regulatory compliance. Fewer wet calibrations reduce the expenses for the calibration program which lead to a better overall equipment effectiveness (OEE) as it increases plant availability.

Less downtime for instrument calibration and fewer unexpected shutdowns will improve operations efficiency and operational excellence. Reliable data, and certified proof that the measured process value is correct, reduce the risk for product quality issues and therefore supports the goal of reaching highest possible patient safety.

• Micropilot FMR63B can extend calibration cycles by means of Heartbeat Technology with Radar Accuracy Index, which allows the radar accuracy of the device to be verifies without process interruption.
• The iTHERM TM371 represents the world’s first RTD sensor capable of fully automated in-situ self-calibration. The patented innovation has been extensively tested and verified in lab and field trials. Read more in our white paper.

Heartbeat Verification is simple. The instrument does not need to be taken out of service, nor the process stopped. The instrument will continue to deliver measuring results throughout. Taking around 30 seconds Heartbeat Verification is also fast. It can be started remotely from the safety of the control room, and flexibly, for example on a daily basis or before a batch. A full Heartbeat Verification report is generated internally in the device every time a device verification is performed.

This report comes in a tamper-proof PDF format and is easily accessible directly from within the instrument. It can be downloaded through any asset management system or via the integrated web server. Using Heartbeat Verification during the lifecycle provides traceable and audit-safe test documentation ready for inspection.
