Detailed explanation-1: -A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine.
Detailed explanation-2: -Airspeed is a measurement of the plane’s speed relative to the air around it. The pitot (pronounced pee-toe) static tube system is an ingenious device used by airplanes and boats for measuring forward speed.
Detailed explanation-3: -A tachometer is an instrument that measures the working speed of an engine, typically in revolutions per minute (RPM). It is commonly used in cars, boats, planes, and other vehicles.
Detailed explanation-4: -An air speed indicator (ASI) is a device for measuring the forward speed of the aircraft. The ASI uses the aircraft pitot-static system to compare pitot and static pressure and thus determine forward speed.
