Expert’s answer: PROMAG 400 Heartbeat Technology 

Promag 400 Heartbeat Technology will give you everything you need to know about your flow meter conditions. If you have the Heartbeat Verification, then you can test all parts of the meter and check the conditions in a technical report.

The report divides the data into sections for the output, transmitter, and sensor. Thus, you can see if your device’s coils and electrodes are in good condition, for example.

Now what if you want the values related to those coils and electrodes, like the low and high limits to see if the sensor is in good condition? Then through FieldCare you can get a report with more information and graphics about the health of your flow meter.
