Transit Time flow meter Theory

Transit Time Flow Meter Principle

The Transit Time flow meter measures the time it takes for an ultrasonic signal transmitted from one transducer to cross a pipe and received by a second transducer.

Flow Standards

Flow Standards

Continuous flow measurement are inferential, that is, we measure flow indirectly by measuring some other variable (such as pressure, time) directly.

Interferometer Principle

Interferometer Principle

The variation of refractive index of flowing gas with density is basic principle used in Interferometer. Interference of light waves is used for measurement

Flowmeter Characteristics

Flow Meter Characteristics

Different Types of Flow Meter Characteristics are Recommended Service, Rangeability, Pressure Loss, pipe diameters, Viscosity Effect and Cost of instruments
