Beschreibung
Zusammenfassung:	The present invention provides an electrochemical apparatus for monitoring flow rate including a membrane having a space that is formed in a middle portion of the membrane and has a preset volume to contain an ionic fluid, a first electrode and a second electrode provided on both sides of the membrane, and a control unit configured to apply a voltage to the first electrode and the second electrode to change a state of the space to a concentration polarization state, wherein the membrane includes a fluid flow passage through which a fluid flows into and out of the space, and the control unit calculates a flow rate based on an ionic current generated by the fluid injected through the fluid flow passage in the concentration polarization state.
