Pros and Cons of different gas flow measurement technologies available in the market which will
help process instrumentation engineers to effectively choose the 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 the best suitable technology.
Below are some important factors to be considered & evaluated with comparing technologies for optimum selections:
– Pipe sizes
– Process conditions such as flow rate, 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 Thermal Mass Flow Meter – Insertion Type
Pros:
1. No moving parts
2. Independent mass flow
3. Pipe size
4. Highest turndown ratio
5. Virtually no pressure drop
6. Better accuracy
7. Easy installation & rugged
Cons:
1. Affected by high moisture content
2. Vulnerable to damage
3. Not suitable for high temperature
4. Flow straightener for short upstream length
