饱和蒸汽密度计算机理

多变量类型具有饱和蒸汽曲线，该曲线是表示蒸汽饱和点的曲线。质量流量是通过根据测量的流体温度和饱和蒸汽曲线计算密度来计算的。

这就是为什么digitalYEWFLO涡街流量计可以通过跟踪流体温度的变化来执行质量流量计算的原因。在过热蒸汽的情况下，密度是根据蒸汽表计算的，压力保持恒定。

使用集成功能，可以定期记录蒸汽的能耗，因此可以将其用作节能改进计划的材料。

Calculation mechanism of saturated vapor density

The multivariable type has a saturation vapor curve, which is a curve representing the saturation point of the vapor. The mass flow rate is calculated by calculating the density from the measured fluid temperature and saturated vapor curve.

This is why the digitalYEWFLO vortex flowmeter can perform mass flow calculations by tracking changes in fluid temperature. In the case of superheated steam, the density is calculated according to the steam meter and the pressure remains constant.

Using the integrated function, the energy consumption of steam can be recorded on a regular basis, so it can be used as a material for energy saving improvement programs.

Can be combined with high temperature

Multivariable type can be used in combination with high process temperature type.

The combination with the high process temperature version extends the upper limit of applicable fluid temperatures, typically from 250 °C to 400 °C.
