A Coriolis mass flowmeter provides measurement independent of the physical properties of the medium such as viscosity and density. The SYS-SMF Coriolis mass flowmeter contains two parallel U-shaped tubes that are oscillated at the bottom of the arc by an oscillator. Sensors A and B on the sides of these tubes measure the frequency and phase shift of the vibrations between the sides. If there is no flow, the two pipes vibrate in phase. Once flow occurs, Coriolis forces cause these tubes to cyclically deform. The greater the speed of the flowing mass, the greater these deformations. Larger distortions mean a larger phase shift of the signals received at points A and B. This phase shift is a direct measure of mass flow. Coriolis mass flowmeters offer some of the best accuracy on the market for both liquids and gases. A Coriolis mass flowmeter does not require straight sections before or after it. It is suitable for extreme temperatures and pressures.
