2 oriolis Mass Flow Meter and ounter Model: PM Description oriolis flow easureent is described as a rect or dynaic technique; it supplies a signal that is proportional to the ass flow, and practically independent of aterial properties, such as conductivity, pressure, viscosity, or teperature. oriolis force occurs when linear otion and rotary otion are superiposed on one another. In industrial systes incorporating this principle, echanical vibrations occur at the point of rotary otion. Fluid flowing through two tubes causes the tubes to resonate. The ass flow alters the phase angle of the vibration, which produces a phase fference between the vibration at the tube inlet and that at the tube outlet. This phase fference is proportional to the ass rate of flow; it is aplified to for the output signal. The resonance frequency of the easuring tube is a function of the resonating ass in the tube, and therefore a function of the eu density. ( regulating circuit ensures that the syste is constantly resonating.) The resonance-frequency splaceent, which arises fro the theral expansion of the aterial of the easuring tube, is copensated by teperature easureent. The easured teperature corresponds to the eu teperature. Fields of application For ass or volue flow easureent. pplication exaples: Fluids and low conductivity solvents Deionized Water Fuel oil Food oil onductive solvents ases avitation should be avoided, as it can effect the vibration of the easuring tubes. Mea, whose properties are siilar to water under noral contions, have no special requireents. However, ea that tend to boil easily, naely hydrocarbons, liquefied gases etc, or with suction conveyance, care should be taken not to exceed the liquid vapour pressure, and cause the liquid to boil.
