What important data does the flowmeter data sheet need?
When measuring, the flowmeter is in volume. The measurement of gas, the output of the flowmeter for volume flow, it can guarantee the accuracy of the data, when the need for mass flow output, need unit conversion, but the gas in different pressure, different temperature and density are different. The greater the pressure, the greater the density, the higher the temperature, the smaller the density. When the flow output is mass flow, a number of factors affect the output data. Upper limit of pressure to consider the maximum capacity of flow, when the pressure is too large, there will be leakage, pipeline burst and so on; when the temperature is too high, should be insulated when necessary link tube shell and header selection of low thermal conductivity material, to prevent the high temperature damage flowmeter. When measuring the gas, the sealing type of the sensor in the shell is better to prevent the gas from entering the meter and affecting the use of the flowmeter. When measuring high pressure corrosive gas, more attention should be paid to the protection, and the material selection is more important, which directly affects the service life of the flowmeter. From selection to use, we need to consider a variety of factors to make the output data more accurate.
At present, a vortex flowmeter based on Carmen vortex principle for flow measurement is called vortex flowmeter. Its range of application, gas, liquid, steam can be measured.
Since the vortex flowmeter has a strict selection standard, the temperature, pressure and flow rate of the measuring medium should be confirmed before selecting, and the suitable flowmeter can be chosen to be used perfectly in the field.
