Coriolis flowmeters
Operating principle: Coriolis flowmeters measure the mass flow of liquid or gas using the Coriolis effect - the inertial force that arises when a substance moves through a vibrating tube. Key features:
- Direct measurement of mass flow (no additional calculations required)
- High accuracy (±0.1-0.5%)
- Independent of the medium’s density, viscosity, and temperature
