An electrochemical apparatus for monitoring a flow rate according to an embodiment of the present invention comprises: a membrane having a space with a predetermined volume formed in the middle thereof, wherein the space accommodates an ionic fluid; a first electrode and a second electrode provided on both sides of the membrane, respectively; and a controller for changing the space into a concentration polarization state by applying a voltage to the first electrode and the second electrode, wherein the membrane comprises a fluid movement channel, through which a fluid can enter and exit the space, and the controller calculates the flow rate on the basis of a value of ion current generated by a fluid injected through the fluid movement channel in the concentration polarization state. Un mode de réalisation de la présente invention concerne un appareil électrochimique pour surveiller un débit, comprenant : une membrane au centre de laquelle est formé un espace ayant un volume prédéterminé, l'espace accueillant un fluide ionique ; une première électrode et une deuxième électrode respectivement disposées sur les deux côtés de la membrane ; et un contrôleur destiné à modifier l'espace en un état de polarisation de concentration en appliquant une tension à la première électrode et à la deuxième électrode, la membrane comprenant un canal de déplacement de fluide à travers lequel un fluide peut entrer et sortir de l'espace, et le contrôleur calculant le débit sur la base d'une valeur de courant d'ions générée par un fluide injecté à travers le canal de déplacement de fluide dans l'état de polarisation de concentration. 본 발명의 일 실시예에 따른 전기화학적 유량모니터링 장치는 소정의 부피를 가지며 이온성 유체를 수용하는 공간이 가운데 형성된 멤브레인; 멤브레인의 양측에 각각 마련된 제1 전극과 제2 전극; 및 제1 전극 및 제2 전극에 전압을 인가하여 공간을 농도 분극 상태로 변하게 하는 제어부를 포함하되, 멤브레인은 공간에 유체가 드나들 수 있는 유체 이동 통로를 포함하는 것이고, 제어부는 농도 분극 상태에서 유체 이동 통로를 통해 주입된 유체에 의해, 발생된 이온 전류값을 기초로 유량을 산출한다.
