Pros and Cons of different gas flow measurement technologies available in the market which will help process instrumentation engineers to effectively choose best flow metering technology for defined application which results in optimum results w.r.t cost versus performance ratio.
Process instrumentation engineer’s task is to identify which of the Mass flow meter technology will be best suitable technology.
Below are some important factors to be considered & evaluated with comparing technologies for optimum selections:
– Pipe sizes
– Process conditions such as flowrate, pressure, temperature, density, viscosity, dirt & moisture etc.
– Installation conditions such as horizontal, vertical or inclined & available straight lengths, time & efforts etc.
– Accuracy & repeatability needed
– Process turndown ratio needed
– Budgeted price
Here are the Pros and Cons of Vortex Flow Meter
Pros :
1. Suitable for liquid, gases and steam applications
2. Better accuracy and repeatability
3. Low initial cost
4. Suitable upto 40 bar
Cons :
1. Creates high pressure drop
2. Susceptible to turbulent and vibration
3. Accuracy gets affected due to viscosity
