AMCA风机应用手册第3部分《现场风机系统性能测量指南》中提出了一些新的想法，这对那些必须对风机进行现场测量的人来说应该是令人兴奋的。它们将为风机性能的现场测量带来新的意义和帮助。本发明还描述了一种利用现场测量的电流和电压信息确定电机功率输出的方法，以及一种通过皮带传动估算功率损耗的方法。本文描述了用于测量脏气流中压力的“管道”类型，并举例说明了改变倾斜压力计上的坡度如何影响管道速度的测量精度。虽然标准AMCA皮托静压管没有多少令人兴奋的地方，但它与其他“标准”项目一起被包括在内，使现场测量手册成为一个独立的仪器。本文将回顾上述项目以及手册中包含的、附录B至S中涵盖的其他支持性信息。 引文:德克萨斯州达拉斯ASHRAE交易会第82卷第1部分研讨会

There are some new ideas presented in AMCA Fan Application Manual, Part 3, A Guide to the Measurement of Fan-System Performance in the Field, which should be exciting to those who have to perform field measurements on fans. They will bring new meaning and assistance to the art of field measurements of fan performance. A method for determining motor power output using field measured current and voltage information is described also described is a method for estimating power losses through belt drives.There is a description of the kind of "tube" used to measure pressures in a dirty gas stream, arid an illustration of how the measuring accuracy of the duct velocity is affected by changing the degree of slope on an inclined manometer.Although there is not much that is exciting about the standard AMCA Pitotstatic tube, it, along with other "standard" items is included to make the field measurement manual a self contained instrument.This paper will review the above items plus other supportive information contained in the Manual and covered by appendixes B through S.
