I finally hooked up my BigNG and sensorbus to my rig yesterday. I only had my RPM signal blue cable going over to the sensorbus to see the flow rate. It is kinda weird though.
It defaults to a sample time of 3 seconds and showed 7.8 l/m flow rate. I changed the sample rate to 2 seconds or 1 second and the flow rate doubles or triples. Not sure what to make of this. I have searched and cannot find the correct impulse rate (509 default).
I am thinking about filling a bucket and try to measure the actual flow rate to calibrate. Anyone else see this behavior or knows what the correct impulse rate is for DDC-2 18W?
