In industrial production processes, different industries choose different flow meters. If measuring ordinary liquids such as tap water and diesel, an elliptical gear flow meter made of ordinary materials is sufficient. However, when measuring super-viscous materials such as polyvinyl alcohol and resins, flow meters made of special materials are required, and high standards are imposed on their quality. When choosing an elliptical gear flow meter, in addition to the material and quality of the product itself, special attention should be paid to after-sales service. Reputable manufacturers will provide a limited-time return and exchange service, and they will also send professional technicians to assist customers with issues related to installation, thereby eliminating their concerns. Customers need to consider various options and make comparisons in order to purchase the flow meter that is best suited for them. Modern industry, particularly the petrochemical and metallurgical sectors, relies on elliptical gear flow meters. Although such instruments can be found everywhere in the market, selecting ones with accurate calculations, high-quality materials, and a long service life requires some effort. The pipeline should be cleaned before installing the helical gear flowmeter. If the liquid contains solid particles, a filter must be installed upstream of the pipeline ； If gas is present, an exhaust device should be installed. Elliptical gear flowmeters have no specific requirements regarding the straight pipe sections before and after them. It can be installed horizontally or vertically. During installation, the elliptical gear rotation axis of the flow meter should be parallel to the ground. An elliptical gear flow meter that has been properly installed as required will ensure sufficient accuracy when in use; typically, the accuracy of the cumulative values can reach 0.5 grade, making it a fairly accurate flow measurement instrument. However, if the flow rate of the medium being measured is too low during use, the effect of the instrument’s leakage error becomes significant, and sufficient measurement accuracy can no longer be ensured. Therefore, different models and specifications of oval gear flow meters have a specified minimum flow rate; only when the actual flow rate being measured is greater than this minimum value can the measurement accuracy be ensured.
