Coriolis Flow Meter


Our range of Coriolis mass flow meters is designed to suit your need to measure almost any fluid, across any application. Built on the Coriolis principle, these meters measure the mass of the fluids directly, rather than volume. This means they do not require compensations for factors such as temperature and pressure which impact volume and in turn, impact the accuracy of measurement.

Our Coriolis flow meter consists of two parallel tubes that are made to oscillate using a magnet. These oscillations are recorded by sensors fitted at the inlet and outlet of each tube. In a no-flow state, the oscillations are synchronized, i.e. in phase with each other, since there is no mass exerting any force on the tubes. On the other hand, any fluid, or gas flowing through the tubes generates Coriolis forces, causing the tubes to twist in proportion to the mass flow rate of the medium.

The magnitude of this twisting is measured by the sensors as a phase shift between the inlet and outlet of the tubes; this phase shift is used to measure the mass flow rate of the medium.
