Flow rate measurement of hostile acids and alkalis can be most suitably done by a/an ________________?
Correct answer: C. Magnetic flow meter
- A. Venturimeter
- B. Orificemeter
- C. Magnetic flow meter
- D. Hot wire anemometer
Explanation
A magnetic flow meter has no obstruction or moving parts and measures conductive liquids using electromagnetic induction. This makes it suitable for corrosive acids and alkalis, where ordinary meters may be damaged.
