Which of the following flow meters is not a type of differential pressure flow meter?
A. Orifice flow meter
B. Venturi flow meter
C. Electromagnetic flow meter
D. Pitot tube flow meter
Answer:C
Which of the following flow meters is not a type of differential pressure flow meter?
A. Orifice flow meter B. Venturi flow meter C. Electromagnetic flow meter D. Pitot tube flow meter
Explanation: Orifice, Venturi, and Pitot tube flow meters are examples of differential pressure flow meters. They work based on the principle that the pressure drop across a restriction in the flow path is proportional to the square of the flow rate. Electromagnetic flow meters, on the other hand, operate based on Faraday’s law of electromagnetic induction and do not require any obstruction in the flow path.
