Why steam measurement need compensation?
Flow meter technologies in steam system?
Steam measurement devices with multivariable vortex meter which designed combines temperature, pressure compensation for steam mass flow measurement are becoming increasingly important in measuring steam(saturated steam or super heated steam) and gas flow.
Although differential pressure (DP) flowmeters are still take a big part in steam flow application, but multivariable flow meters have some clear advantages compared to DP flowmeters and Orifice, V-Cone, Wedge etc. For example, the multi-variable vortex mass flow meters have very lower pressure drop than Orifice and 30:1 quite turndown ratio. Not even the high accuracy 1%RD can in custody transfer in most gas flow area. They can tolerate the high temperature in superheated steam. There are some other important developments in vortex like dual sensor vortex meters that provide.
With improved versions of Vortex Meter many critical challenges have been resolved. Multivariable vortex meter is a great choice on steam and other gas applications use and advancement in Multivariable Transmitter they could achieve great results.
