Abstract
To design an electromagnetic flow meter for monitoring the exudates drain process from a cerebrospinal and surgical wound.According to Faraday electromagnetic induction principle , a low frequency square wave excitation mode and a single chip mi-crocomputer control system were adopted to design an optimal scheme and verify the experiment .The measurement accuracy and repeti-tion error of the prototype can meet the requirements .The prototype has stable quality and can meet the needs of clinical monitoring of the exudates from surgical wound drainage process .It provides a safe and convenient means of postoperative care .关键词
