This paper introduces the study of testing velocity instruments by the model test, major presents the propeller current meter, electric magnetic velocity meter and the ultrasonic velocity meter. 分析研究了用于模型试验的流速测量传感器和相关仪器,重点介绍了旋浆流速仪、电磁流速仪和超声波流速仪。
To use the elements, you should prepare the adjustable transformer or silicon controlled transformer, voltage meter, current meter and autocontrol temperature meter etc. 使用元件必须配备调压变压器或可控硅调压器及电压、电流表(CM)和温度自动控制仪表等。
A new portable propeller-type current meter BH-1 is introduced, which consists of three parts : flow velocity sensor, signal process circuit and data analysis software. 介绍了一种新型BH-1型便携式旋桨流速仪,主要由自主研制的流速传感器、手持式主机及微机数据回放处理软件三部分组成。
In this paper, we applied JTFA techniques to the residual flow data collected from a current meter and obtained valuable results, which could not have been obtained using conventional signal processing methods. 本文采用这种方法处理了海流观测资料中的余流,取得了用传统方法得不到的有用结果。
