A mass flowmeter measures flow rate in weight per unit time rather than volume. This measurement compensates for temperature and pressure changes. Fluid moving through a vibrating tube is forced to accelerate as it moves toward the point of peak amplitude of vibration. The fluid decelerate as it moves away from the point of peak amplitude. The acceleration and deceleration cause twisting forces on the flowtube which are proportional to the mass flow.
