Description of the misunderstanding about the selection and use of the flowmeter

Flowmeter is a kind of instrument for measuring flow, mainly used in industrial production process, energy metering, environmental protection engineering, transportation, biotechnology, scientific experiment, marine meteorology, rivers and lakes and other fields. Flow measurement is the science of material quality change. The law of quality mutual change is the basic law of the development of the relationship between things. Therefore, the measurement object is not limited to the pipeline liquid in the traditional sense. The flow measurement problem is wherever there is a change in volume. Flow, pressure and temperature are listed as three major test parameters. For a certain fluid, as long as you know these three parameters, you can calculate the energy it has. These three parameters must be detected in the energy conversion measurement. Energy conversion is the basis of all production processes and scientific experiments, so flow is the most widely used for pressure and temperature instruments. The main flowmeter uses the user to select and use the flowmeter and the operation has certain misunderstandings. The main categories can be roughly classified into the following categories:
1. Blindly believe in imported flowmeters: This idea is reflected in many Chinese people, not only in terms of flowmeters, but also in many other materials. Imported products are better than domestic ones. In fact, through decades of study and research and development, domestically produced flowmeter products are technically capable of importing products outside the United States. A part of domestically produced flowmeters can completely replace foreign imported products. For example, Changzhou Chengfeng Instrument's R/F/G series glass rotor flowmeters have higher precision in pressure and high temperature resistance. The traditional glass rotor flowmeters are coming high, and they are completely out of the United States.
2, think that the expensive is good: this is also a common problem in the market now, although the saying goes: the price is not good, the good goods are not cheap, but buy the flow meter is not to buy the price, but to choose the most Appropriate, only the most suitable is the best, in order to accurately measure the media flow.
3, only according to the pipe diameter selection: only according to the diameter of the pipe to choose the size of the flowmeter, the connection form of the flowmeter, etc., but the other influences of the flowmeter selection also have many parameters, flow range, flow medium, temperature, Pressure, density, and corrosiveness are all issues to consider. Some customers buy a flow meter, but use it in different situations. This is wrong because the pressure of different media in the place and the flow range are different. There is currently no flow meter available on the market for any application, and no flow meter can be used to measure any medium.
4. The parameters are not set after installation and installation according to the installation requirements.
Different flowmeters have different installation requirements on site. It is recommended to use the installation under the guidance of professionals.
