watt meter

基本解释

For this purpose a special cleaning system is made. Acoustic power in the liquid is measured with a Watt meter.
制作了一个专门的超声清洗系统，并用瓦特计法测定清洗液中得到的声功率，同时用一个探头从清洗液中提取信号；
The paper presents the design of non-sinusoidal waveforms Watt-meter, which based on the system SCM of high-speed chip C8051F.
提出了一种以C8051F高速片上系统单片机为核心的非正弦波功率表的设计。
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.
计量误差考虑了电度表电压线圈和电流线圈在不同的谐波次数以及谐波大小时的非线性效应。

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