3. Differentiate between ultrasonic flowmeter and radar
type flow meter.

Answer Posted / Surendra Singh Laspal

Ultrasonic flowmeters measure the velocity of fluid particles by sending high-frequency sound waves (ultrasonic) through the pipe, while radar type flow meters use microwave or radio frequencies to measure the velocity of the fluid. Ultrasonic flowmeters are used for clean, non-conductive fluids and can be affected by solid content, air bubbles, or rough pipe walls, while radar flowmeters can handle various types of fluids, including dirty or conductive ones. They are also unaffected by pipe materials and temperature variations.
