Abstract: The information on misunderstandings in the selection of flowmeters is provided by excellent flowmeters and flowmeter manufacturers. 1. Blindly superstitious imported products Most people think that imported products are definitely good. The author's experience in flow meters for more than ten years has confirmed that domestic products are cost-effective (except for flow meters that cannot be produced domestically); imported meters are used to purchase theirs. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article on the selection misunderstanding of flowmeters. 1. Blindly superstitious imported products A large part of people think that imported products are definitely good. The author's experience in flow meters for more than ten years has confirmed that domestic products are cost-effective (except for flow meters that cannot be produced domestically); when using imported meters to purchase their products, in addition to paying expensive money, future after-sales service It is also difficult to guarantee (you have to wait a month for a small accessory, and you have to pay dozens of times the domestic price) 2. Superstition is expensive, but good is good, and there are two reasons why it is expensive in flow meters. Types: one is the pricing method of the manufacturer; the other is because the total production volume is too small, and the revenue can only be increased by increasing the profit of a single unit. 3. Superstition of the same meter manufacturer. After purchasing a flow meter from a manufacturer, some manufacturers believe that both parties have established a certain reputation foundation, but they do not know that the flow meter is also a big family of nearly 100 products, and there is no domestic one. Flowmeter manufacturers dare to say that we can produce any kind of flowmeter. This can be reflected in their price and future after-sales service. 4. Blind selection of new flowmeters When purchasing flowmeters, don't be fooled by the manufacturer's salesman, they are often experimenting with you. Maybe the calibration before leaving the factory is qualified, but is the long-term operation reliable? Can it really meet your requirements? After all, the upgrading of flow meters is not as fast as mobile phones and TVs, and the old ones can stand the test of the market! Driving a Jetta is always better than driving. 5. Only according to the pipeline selection This is the most likely situation, and the result is often that the ideal measurement effect cannot be achieved. It is not the quality problem of the flowmeter itself, the flowmeter is also a measuring instrument, which has its own measuring range. 6. The type selection is not based on the type of medium Although there are not many cases in this situation, it is true that the vortex flowmeter is used to measure the mud on the spot. 7. A flowmeter can measure any flow. Some irresponsible manufacturers and salesmen will tell you that our flowmeter can measure everything. If you hear this sentence, you can tell him“Please”Get out of your office, because he is talking nonsense to you! Eight, not installed in accordance with the installation requirements For example, many flow meters require sufficient front and rear straight pipe sections. Please read the instruction manual carefully before installing the flowmeter to avoid unnecessary trouble. 9. The parameters are not set after installation. Most of these situations will occur in battery-powered flowmeters. It is determined that the parameters have been set by the manufacturer and can be used after installation. This may cause large measurement errors and unnecessary 10. Failure to carry out maintenance on time will cause the accuracy of the flowmeter to decline, and the manufacturer can tell you how to maintain it, just like the car has to be sent to the after-sales service center for maintenance after a period of time. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Misunderstanding of the selection of flow meter'
