I took a quick look at those earlier, I couldn't determine how fast they could read or if they could measure to a moving piece/variable measurements. Or if the pieces need to be stationary. Ideally think it should be able to read a variable height and stream measurements ,as they read, to the arduino which would then isolate the highest and lowest readings , it would be nice to be able to export those reading to another step or program but as long as you could find and read them. that would work
