Question

Which one is not a flowmeter


Orifice meter


Pitot tube


Rotameter


Potentiometer​

Answer 1

Answer:

the correct answer is

potentiometer

Answer 2

The option which is not the flow meters is option 4th option: Potentiometer.

• Flowmeters as the name says is the measurement device used to measure the rate at which fluid is flowing. It can be gas or liquid.
• From the given options Orifice meter, Pitot meter and Rotameter are all the flow meters in unit operation and engineering. All have different instrumental setups as well as operational characteristics but are used to measure the velocity of the fluid.
• However, the potentiometer is a device used in electronics.
• It measures how much voltage is dropped in the wire segment when the current is flowing or the electromotive force of two cells is compared.
• Hence, a potentiometer is an instrument which is not a flowmeter type.
