Just as you said, 203 is right. However, the numbers are like 182, 179, 190, 204, 206....Then the voltage I measured is staying at 0.994. Is that still right? Also, if I increase the flow rate, like the output increases to 1.212V, the numbers I read are like 210, 249, 208, 257, 242, 225, 248, 198, 232, 196...
I mean when the output from my sensor is increased, the data I read is more unstable....
