摘要：

In this paper, we developed a quartz oscillator based liquid concentration sensor for contactless monitoring of water treatment process. This sensor is composed of the sensing capacitor (SC) and quartz crystal resonator (QCR). The proposed sensor is a contactless capacitive sensor using out-of-plane electric field of a planer sensing capacitor. We succeeded in measuring flocculation reaction of coagulant and sewage. This study is expected to reduce the time significantly to determine the amount of coagulant and to develop automatic control of the water treatment process. © 2020 The Institute of Electrical Engineers of Japan.
