[Summary] Vapour flowmeter is measured is heat addition industry one of metric job main content, as a result of the characteristic of the industry, spot moving appearance often is come up against super- measure type selecting of computation of limits, density, appearance to wait for a problem. The article from the introduction contemporary flowmeter measures technical proceed with, union is current heat addition enterprise is metric run requirement, the vapour discharge metrological implement that put forward to had won success application provides program, this plan solved vapour discharge wide span, high accuracy, energy metric, data gets online wait for the new requirement with contemporary metric heat addition.

1 preface

Vapour is the main heat addition medium in industry of town heat addition, raise steam so production, carry it is OK to reach use efficiency managing and many energy resources. Accurate metric it is the key that improves energy level of management. As a result of steam characteristic, put in a lot of difficulty in metric respect, long-term since it is industry of town heat addition all the time the long-standing problem in metric job, work up suits characteristic of enterprise of heat addition of our country town one set, have scientific sex, economy, practical vapour is metric the equipment of appearance plan, it is current town heat addition the urgent task that metric managing. At present vapour discharge measures what basically use or this measures standard throttle unit traditionally method, but groovy orifice plate flowmeter measures a respect to still have a lot of inadequacy in vapour, main body measures range now small, pressure damage is big, field assembly, safeguard complex, calibrating the respect such as cycle weak point. Measure the weakness with little scope especially, metric below the case with thermic load big change error increases greatly, make heat addition enterprise gets pecuniary loss. Current, adopt modern technology measure, can solve these problems well, in the light of these the problem undertakes an analysis below, put forward a reasonable vapour discharge metrological implement to provide program.
