![]() when I said 6" I ment out of a total of 24" 6 would be air and 18 would be water.
I got the sensor (calibrated for electric light) and a digital multimeter that it is hooked to. thats good the error ws that small, I have always done 12" as a base. I know the others are using smaller distances but 12" always seamed more realistic to me. Steve
