Select the ten misunderstandings of the flowmeter

First, blindly superstitious imported
A large number of people think that imports are definitely the best. The author's experience in flow meter for more than ten years has confirmed that the domestically produced is the most cost-effective (except for the flowmeters that cannot be produced domestically); the imported instruments are not only expensive but also expensive after the purchase of their products. It's also hard to guarantee (a small accessory has to wait for a month, and you have to pay tens of times the domestic price)
Second, superstition is good is good
There are two reasons for the expensive in the flow meter: one is the pricing method of the manufacturer; the other is because the total production is too small, and can only increase the profit by increasing the profit of a single unit.
Third, blindly superstitious same flowmeter manufacturers
Some people have purchased a flowmeter from a manufacturer and believe that both parties have established a certain reputation. They do not know that the flow meter is also a large family of nearly one hundred products. No domestic flowmeter manufacturer dares to say us. What flow meters can be produced. This can be reflected in their selling price and future after-sales service.

Fourth, blindly choose a new flowmeter
Don't be fooled by the factory clerk, they are often taking experiments with you. Maybe the calibration before leaving the factory is qualified, but is it reliable for long-term operation? Can you really meet your requirements? After all, the upgrade of the flowmeter is not as fast as mobile phones and TVs, and the old ones can stand the test of the market! Driving Jetta is better than opening QQ.
Fifth, only according to pipeline selection
This is the most prone situation, and the result is often not the ideal measurement. Not the quality of the flow meter itself, the flow meter is also a measuring instrument, it has its own measurement range.
Sixth, not based on the type of media selection
Although this situation does not appear a lot, but I have seen the use of vortex flowmeter to measure mud.

Seven, a flow meter can measure what flow rate
Some irresponsible manufacturers and salesmen will tell you what our flowmeter can measure. If you hear this sentence, you can "please" him out of your office because he is talking nonsense to you!
Eight, did not install according to the installation requirements
For example, many flow meters require sufficient front and rear straight sections. Please read the instruction manual carefully before installing the flowmeter to avoid unnecessary trouble.
Nine, do not set the parameters after installation
Most of them will appear in the battery-powered flowmeter. It is determined that the parameter manufacturer has been set up and can be used for installation. This may cause large measurement errors and unnecessary losses.
X. Failure to maintain on time
This will cause the accuracy of the flowmeter to drop, allowing the manufacturer to tell you how to maintain it, just like the car has to be sent to the after-sales service center for a period of time. Because of the different maintenance methods of various flow meters, the author is not suitable for this case.
