Continuous float monitoring (CFM) in VA flowmeters
Enhanced application diagnostics for increased process reliability
Challenge
Float blockages caused by dirt or pressure bumps as well as compressional vibrations from gas or intermittent flows can have a severe impact on variable area (VA) flow measurement and the lifetime of a VA flowmeter.
Solution
The H250 M40 variable area flowmeter offers additional application diagnostics as well as device diagnostics to increase application reliability. The new CFM function monitor the motion pattern of the float using innovative software algorithms. Corrective measures can thus be taken to improve flowmeter accuracy and service life.
Safety benefits
Float blockages due to dirt and pressure bumps reliably detected
Detection of compressional vibrations of float in gas measurements
Monitoring float issues related to pulsating flows in liquid measurements caused by displacement pumps
Identifying incorrectly fitted floats after maintenance
Advanced diagnostics to take corrective measures for process optimisation
Notification alerts can be classified from purely informative to device errors with failure current output (acc. to NAMUR NE107)
The intelligent modularity of the H250 M40 allows a functional upgrade of existing devices with CFM in the field
