Engineering Instruments Quiz

RVDT stands for Rotary Variable Differential Transformer, which works on the principle of electromagnetic induction to measure angular displacement.

Some types of flow meters include electromagnetic flow meters, turbine flow meters, and ultrasonic flow meters.

A Hot Wire Anemometer works on the principle of convective heat transfer. The wire in the anemometer is heated, and the cooling effect of the air flow is used to measure the velocity of the air.
