Thermal Mass Flow Meters for Gases: Working Principle, Key Features, and Industrial Applications
2026-05-25

Working Principle Thermal mass flow meters measure gas flow by detecting the cooling effect of the gas stream on a heated sensor element. Since they measure mass flow directly, they eliminate the need for separate pressure and temperature compensation required by volumetric flowmeters. Two Primary ...

Vortex Flowmeters: Working Principle, Key Advantages, and Industrial Flow Measurement Applications
2026-05-25

Working Principle The vortex flowmeter operates based on the Kármán vortex street phenomenon. When fluid flows past a bluff body, alternating vortices are generated downstream. The shedding frequency (F) is directly proportional to fluid velocity (u): F = St · u / d Symbol Parameter Typical Value ...
