Advanced diagnostics for electromagnetic flowmeters

Device and process monitoring functionalities for increased application safety

Challenge

Excessive vibrations, extreme temperature, magnetic field effects, product-build up or medium properties such as corrosiveness affect the performance of electromagnetic flowmeters (EMF). If undetected, those external and process effects lead to a loss of process reliability and, if hazardous media are involved, threaten plant as well as occupational safety.

Solution

To detect disturbing influences fast and reliably, KROHNE EMFs have built-in self-diagnostic functions for the continuous monitoring of readings and the detection of process-related issues. This includes constant monitoring of electronics and sensor hardware, out-of-spec testing and other test routines to e.g. identify contamination, leakages or liner deformation.

Safety benefits

Extensive device and application diagnostics for monitoring external and process effects on the measurement
Self-check functionality for constant monitoring of electronics and sensor hardware
Out-of-spec testing detects unexpected flow changes, linearity issues and uncertain measurements
Continuous monitoring to detect leakages, contamination, liner deformation or air entrainment in the process liquid
Electrode circuit resistance monitoring detects anomalies such as isolation instantly
Indication of product change using integrated conductivity measurement
