Installation error - there is insufficient upstream and
downstream straight run piping for flow conditioning.

Failure to understand that all vortex do low flow cutoff at
approximately 10% of flow because there are not enough
vortices formed to produce an accurate flow rate
measurement. Low velocity flow rate in a steam header can
indicate zero flow even when the boiler is operating with
reasonable loads.

Corrosive fluid destroys the thin sensor membranes.
