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 a Turbine Flow Meter :
Pros :
1. Derives Volumetric Flow rate
2. High accuracy
3. Orientation Flexible
4. Low Initial Cost
5. Suitable High pressure
Cons :
1. Dry and Clean Gas
2. Susceptible to Vibrations
3. High wear factor
