，涡街流量计测量蒸汽有三种 Vortex flowmeters are most commonly used in steam measurement. There are three types of vortex flowmeters for measuring steam.
；这是一种间接式涡街质量流量计、实际使用过程中通过温度和压力的测量间接测算出密度、再与涡街流量计量出 1. It is also the most widely used vortex flowmeter with temperature and pressure compensation. This is an indirect vortex mass flowmeter. In actual use, the density is calculated indirectly through the measurement of temperature and pressure. Flow meter
Multiplying the number of volumes can calculate the mass; this is the most common form of steam measurement by vortex flowmeters;
2. Differential pressure vortex flowmeter, differential pressure signal + vortex flowmeter = differential pressure vortex mass flowmeter. The differential pressure signal is the pressure difference between the two pressure-receiving holes at specific locations on the body and downstream. The axis of the two pressure holes should be related to the axis of the generator
In the same plane. The distance of the pressure hole has a significant effect on the size and stability of the differential pressure value. Short distance, large differential pressure signal, but poor stability; long distance. The opposite is true. Through experiments, it is important to choose a suitable location for taking out the pressure. He Sheng
Compared to force vortex mass flow meters, this instrument is simpler and easier to implement. Domestic manufacturers have invested in development and obtained invention patents, and the products have been applied in some enterprises
，直接测量介质的质量。 3. The lift type vortex flowmeter directly measures the quality of the medium. The theoretical basis is: the mass flow rate of the medium has a certain proportional relationship with the intensity of the vortex, and by calculating the intensity of the vortex, the mass of the medium can be directly calculated.
