Wake Frequency Calculation

The modern vortex-shedding flowmeter can be set-up electronically for particular gases or liquids, so there really isn't any need to worry. Simply follow the set-up instructions in the original equipment manufacturer's information that comes with the instrument.

Sorry i framed wrong ques!!

What i wanted to ask is , in case of thermowells we do wake frequency calc. Either gases or liquids are tough to handle here , wat gives more vibrations??

It depends upon operating conditions of course, but generally speaking, liquids are much denser than gases and are incompressible, so they'll give more vibrations.

it depends on fluid velocity, not fluid state , you can refer ASME PTC 19.3 standard for thermowell wake frequecy calculation.

Wake Frequency is much dependent on Velocity of the Flowing fluid -Its not dependent on state of the fluid

So shall i assume , if velocity is same then liquid will have more impact comapared to gases.

Whats Ur application

According to New ASME PTC 19.3 TW-2010.

The max frequency ratio limit for Liquid phase - 0.4

The max frequency ratio limit for Gas phase - 0.8
