The existing density compensator model does not fit high temperature and pressure saturated vapor, the density compensator precision is low and causes big error in saturated vapor measurement.

现有的密度补偿模型不适合高温高压饱和蒸汽的流量测量，密度补偿精度较低，导致蒸汽流量测量误差较大。

Moreover, it has a very high perforation density, so that a small surface area is sufficient for effective measurement.

此外，它具有非常高的孔眼密度，以便小的表面区域就足够用于有效测量。
