A blind superstition imports

A large part of the people think that the import is definitely the best. The author engaged in the flow meter for more than ten years of experience in the domestic is the most cost-effective (domestic production not only); the use of imported instruments in the purchase of their products, in addition to pay expensive money, after the service is also very difficult to be able to guarantee (a small accessories have to let you wait a month, but also to pay dozens of times in the domestic price)

Two, superstition expensive is good

In the flow meter of noble reason nothing else but there are two: one is the pricing of manufacturers; a is because the total production is really too small, only by improving single profit to increase revenue.

Three, blind superstition with a flow meter factory

Some people in the purchase of a manufacturer of a flow meter, the two sides have established a certain reputation based, but also do not know the flow meter is a large family of nearly 100 kinds of products, there is no one in the domestic manufacturers dare say we can not say anything about the production of. This can be reflected in their price and future sales service can be reflected.

Four, blind selection of new type flow meter

Don't be fooled by the manufacturers, they tend to take you to do the experiment. Maybe ex factory verification is qualified, but the long-term operation is reliable? Can really meet your requirements? The upgrading of the meter is not as fast as the mobile phone, TV, the old is able to withstand the test of the market! Open Jetta than QQ open mind.

Five, only according to pipe selection

This is the most prone to occur, the results are often can not achieve the desired results. It is not the quality of the flowmeter itself, and it is also a kind of measuring instrument, which has its own measurement range.

Six, not according to the medium type selection

Although this situation is not a lot, but I did see the use of vortex flowmeter to measure mud.

Seven, a flow meter what traffic can be measured

Some irresponsible manufacturers and business members will tell you that we can measure the flow meter, if you hear this sentence can be he "please" out of your office, because he was talking nonsense to you!

Eight, not in accordance with the installation requirements for installation

For example, a lot of flow meters are required to have adequate and straight pipe section. Please read the instruction carefully before installing the flow meter, and avoid unnecessary trouble.

Nine, after the installation is not set the parameters

Most will appear in the battery powered meter, the identification of the parameters of the factory has been set up, the installation will be able to use, which may cause a lot of measurement errors and unnecessary loss.

Ten, not on time maintenance

This will result in the accuracy of the flow meter, you can let the manufacturers tell you how to maintain, like a car after a period of time to be sent to the service center maintenance.
