You can also save values and made a chart in myGHL
But - I´ll think that the problem is to find an air flow meter that manage to measure a skimmers low pressure flow and leave a 1-10 V signal - maybe you can find it in the medical industry
Yeah - Thanks @Gaël and @Lasse . I have the card and the 2 x 1-10v inputs are currently unused. As you pointed out @Lasse my issue is the actual flow meter - I was hoping someone else had managed to source something that works.
