ELLIPSE-WHEEL TYPE FLOW METER

The utility model relates to an ellipse-wheel type flow meter, being suitable for liquid flow meters in petrochemical industry, metallurgical industry, and other industries. The utility model has the advantages of high precision, good reproducibility, wide range of flow rate, and suitability for various viscosity and pressure. The structural characteristics are that a metering room which is arranged on a shell body is provided with a pair of ellipse-wheels each of which is provided with a long axis and a minor axis; at the installing time, a 90 DEG angle is formed between the long diameters of the two ellipse-wheels; the differential pressure of liquid enables the ellipse-wheels to rotate, measured liquid is pushed to an outlet, and metering is carried out. The utility model which belongs to a volumetric flow meter also has the advantages of simple structure, low processing cost, and explosion prevention, having the same use method as a gear type flow meter.
