摘要
本文对低功耗电磁流量计的测量电路进行了研究,给出了测量电路的基本组成。根据被测信号的特点,即微弱信号在强干扰下的测量,阐述了测量电路的工作原理。本测量电路主要用于电池供电的电磁流量计中,可以实现便携式低功耗的工作要求。
100029)The measuring circuit of an electromagnetic flowmeter with low power was studied. Because of strong interference and noise, a special circuit was designed to improve the signal-to-noise ratio. Current design can be used in the electromagnetic flowmeter operated with battery and is particularly useful for measuring flow in the field.
