Wide turndown ratios gas mass flowmeter

摘要

The novel intelligent wide turndown ratios gas flowmeter adopts thermal measurement principle when there is little blow and adopts the vortex principle as the velocity increases and goes into the vortex flowmeter's sensitive range. This gas mass flowmeter has been proven to have wide turndown ratios and can avoid leakage at low flow rate after long-time stable operation for pipeline gas measurement.
