Flow Meters

Coriolis Mass Flow Meters

Coriolis flowmeters were developed for liquid flow metering. However, advances in Coriolis technology have made it possible to use them for gases. Unlike thermal mass meters which are excellent for low pressure and low flow rates, Coriolis flowmeters work best with higher pressures and flow rates.

Description

BUILT TO LAST

Coriolis mass flow meter operating principle involves inducing a vibration of the flow tube through which the fluid passes. The vibration, though it is not completely circular, provides the rotating reference frame which gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift, and amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
