Does K-factor for a vortex flowmeter depend on the Process Fluid?
Does K-factor for a vortex flowmeter depend on the Process Fluid?
(OP)
I am using a Rosemont vortex flowmeter (8800 series)and that comes with a K-factor stamped on a nameplate.
Now, obviously, a vortex type meter is not a true mass flow sensor (e.g. a Corolois) but a volumetric flow meter. Now my question is suppose the original fluid changes from A to B (both liquids) does the K-factor change too or not?
The meters are originally all calibrated on water but what I am not sure is whether the K-factor they stamp takes into account any other properties of the fluid for which the meter was ordered for.

To a ChE, the glass is always full - 1/2 air and 1/2 water.

No not pressure drop. But for flow measurement.

Flow calibration
Meter bodies are flow-calibrated and assigned a unique
calibration factor (K-factor) at the factory. The calibration factor
is entered into the electronics, enabling interchangeability of
electronics and/or sensors without calculations or compromise
in accuracy of the calibrated meter body

No mention of fluid properties. I'd call my Rosemount rep. if I was you.

I did! :) But the quality of their reps seems so bad that I'd rather trust a smart anonymous person on a forum than them!
Seriously, I get the feeling that unless you are buying hundreds of thousands worth of hardware the Suppliers shovel you to some newbie tech who has barely any idea.
