In the flow meter industry, selection is an important issue. There are a wide variety of flowmeters, and each type has its own unique advantages; of course, it also has its shortcomings, making them suitable for different applications. Therefore, it is very necessary to choose a flow meter that is suitable for different operating conditions and environments; this selection process is extremely important. Chengfeng Instruments is a flow meter manufacturer with over 30 years of experience. It often receives inquiries from customers asking about the price of glass rotor flow meters and electromagnetic flow meters. However, these customers frequently lack the parameters necessary for selecting the appropriate flow meter. Flow meters are generally chosen based on factors such as the customer’s operating environment; without specific parameters, it becomes very difficult to make a suitable selection, which also makes it hard to provide an accurate quote to the customer. What specific parameters are needed for selecting a flow meter? Bore size, temperature, pressure, medium, density, measurement range, connection type, accuracy class, explosion protection rating requirements, and so on. For example, if the medium is corrosive, the flow meter must be lined with a corrosion-resistant material ； When the fluid medium is sewage or wastewater, an electromagnetic flowmeter should be used ； For liquid media that do not conduct electricity, it is absolutely impossible to use an electromagnetic flowmeter, and so on. For example, regarding the connection method, there are various ways to connect flow meters to pipes: pipe thread connections, flange connections, sanitary clamp connections, and so on. The selection of flow meter must be made based on the customer’s operational conditions. In general, when selecting a flow meter for a customer, it is necessary to ensure that the flow meter is suitable for the intended use, meets the customer’s requirements regarding measurement accuracy, and that its price is within the customer’s budget.
