基本解释

For this purpose a special cleaning system is made. Acoustic power in the liquid is measured with a Watt meter.
制作了一個專門的超聲清洗系統，竝用瓦特計法測定清洗液中得到的聲功率，同時用一個探頭從清洗液中提取信號；
The paper presents the design of non-sinusoidal waveforms Watt-meter, which based on the system SCM of high-speed chip C8051F.
提出了一種以C8051F高速片上系統單片機爲核心的非正弦波功率表的設計。
The metering error considers the non linear effect of the voltage coil and current coil in watt hour meter under different order of harmonics and different distortion degree of input waveform.
計量誤差考慮了電度表電壓線圈和電流線圈在不同的諧波次數以及諧波大小時的非線性傚應。

More intriguingly, the Kill A Watt meter will also tell you how much electricity you are wasting unwittingly.
