FLUID MEASURING APPARATUS
First Claim
1. A fluid measuring apparatus, comprising:
- a collector, comprising a first cavity, a first inlet, and a first outlet, the first cavity comprising a first inner wall and a second inner wall;
a first sensing circuit, comprising a first electrode disposed on the first inner wall and a second electrode disposed on the second inner wall; and
a first electrochromic device, electrically connected to the first sensing circuit;
wherein when the first sensing circuit is enabled, a color of the first electrochromic device changes if a concentration of a fluid flowing through and between the first electrode and the second electrode varies.

Abstract
The invention provides a fluid measuring apparatus, which includes a collector, a sensing circuit, and an electrochromic device electrically connected to the sensing circuit. When the concentration of a fluid flowing through the collector and between the sensing circuit varies, the color of the electrochromic device changes accordingly. Further, the electrochromic device includes an electrochromic material, and the sensing circuit includes a first electrode and a second electrode, wherein the first and the second electrodes are disposed in the collector and the electrochromic material is disposed on the first electrode. When the concentration of an electrolytic solution flowing between the first electrode and the second electrode varies, the color of the electrochromic material changes accordingly.
