Question:
Which of the following flow meters offers the lowest resistance to the flow?
Which of the following flow meters offers the lowest resistance to the flow?
Show Hint
If minimum flow resistance is required, electromagnetic flow meters are the best choice since they are obstruction-less.

- Turbine flow meter
- Orifice flow meter
- Venturi meter
- Electromagnetic flow meter
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand flow resistance.
Flow resistance depends on pressure drop across the meter. Devices like orifice plates and venturi meters create a significant pressure drop, hence higher resistance.
Step 2: Evaluate options.
- (A) Turbine flow meter → introduces moving parts and obstruction, hence moderate resistance.
- (B) Orifice flow meter → creates high permanent pressure loss, highest resistance.
- (C) Venturi meter → less resistance than orifice, but still causes some pressure drop.
- (D) Electromagnetic flow meter → has no obstruction to flow; measures velocity using Faraday’s law. It offers virtually zero resistance.
Thus, the electromagnetic flow meter offers the lowest resistance.
