There are presented the developments ensured by a new worldwide flow measurement structure, based on the reaction force, "the extended reaction flowmeter" ,elaborated by the first author, the subject matter of the patent application filed with European Patent Office EP 21020546, together other reaction flowmeters without moving parts. Initially are synthetically reitered the constructive and structural specificities of "the extended reaction flowmeters "(shortly "ERF"). Then, starting from the facilities offered by the specific structural scheme of the ERF, significant simplified compared to that of the known compound flowmeters, are presented the developments offered by the using of this new flow measurement structure based on reaction force, by describing the improuved results achieved by two constructive variants of ERF, regarding the binomial of the two essential features (turndown and accuracy, interrelated of the flowmeters, by achieving a large extension of the turndown to very important values, correlated with an optimal range of the accuracy values.

In order to improve the performance of the old Stack Simulator, NIM built two new facilities. One is a close loop wind tunnel, which can simulate the real flue gas conditions. The wind tunnel can change the flow rate, temperature, pressure, gas composition and turbulence in the test section. It is used to calibrate the velocity measurement devices such as three-dimensional pitot tubes used in Relative Accuracy Test Audit (RATA). Another facility is a new Stack Simulator, which can simulate the flow field conditions in the real stack. It is used to evaluate the average velocity measurement of RATA devices.
