1. According to the requirements of measurement intention:
It is required to select the instantaneous flow rate or the cumulative flow rate (cumulative flow), the unit of flow display, measurement accuracy, repeatability, linearity, flow scale and scale, measurement temperature, pressure loss, temperature and pressure compensation, output signal characteristics and response time, etc. Different measurement targets have their own measurement intentions, and have different emphases in the function of turbine flowmeters.
2. Requirements for measuring the properties of the medium:
Chemical corrosion and fouling, the chemistry of the fluid can sometimes be the determining factor in the selection of measurement methods and appearances. Some fluids can cause corrosion of surface contact parts, surface fouling, or electrolytic chemistry on the metal surface of the crystal.
3. Requirements for measuring the phase of the medium:
Depending on whether the measurement medium is a single phase change medium, or whether it is a multiphase and multi-component activity, it should be treated with caution. The turbine flowmeter can measure a single clean medium, and the electromagnetic flowmeter can measure the solid-liquid two-phase mixed medium.
4. Turbine flowmeter is a common type of flow, which can measure various gases and liquids. It uses a new intelligent planning to maintain high-precision measurement when it is used. The function of the turbine flowmeter in use is superior, the service life is very long, and it has a strong anti-disturbance ability, in the use of the time, the turbine flowmeter may encounter a variety of electromagnetic disturbances, if the anti-turbulence of the flowmeter is not good enough, the measurement accuracy of the flowmeter may be affected at the time of use.
When the turbine flowmeter is in use, the power consumption is small, and the stainless steel structure is selected, which can ensure that it has a strong anti-corrosion function during the application, and it is not simply corroded, and for some corrosive media, the turbine flowmeter can also be measured well and will not be restricted. This turbine flowmeter is very small, if there is a problem during use, it is very simple to disassemble the flowmeter, which is convenient for the user to repair in time, and after daily use, when the flowmeter needs to be cleaned, simple disassembly and assembly also makes it more convenient for the user to clean
5. Measurement accuracy requirements:
It is necessary to have a clear overall measurement accuracy requirement and whether it is used under a specific flow rate, or there is a significant change due to the change of temperature and pressure in a certain scale of measurement, and its value is generally low, and the difference between various gases is small. The commonly used accuracy grades of intelligent liquid turbine flowmeters are 1.0 and 0.5, which are higher than general rotameter flowmeters, and are a good choice for customers with high accuracy requirements.

Schneider online UPS power supply is energy-saving
1. The need for stability
When choosing UPS products, the customer's focus must be stability. For UPS, higher power means lower calorific value. Of course, only one of the primary factors that affect the internal temperature of the UPS is also to consider the heat dissipation planning of the machine itself.

Motor control mode of Schneider inverter
Fundamentals of magnetic flux vector manipulation
The control of a three-phase asynchronous motor is much more complicated than that of a DC motor because the current, voltage, induced potential, magnetic flux, etc., of the stator and rotor are all alternating.
However, the stator winding of the three-phase asynchronous motor is a symmetrical three-phase winding, which exerts a ...
