So after many weeks of waiting and a couple days of figuring out how to set the Profilux 4 up, I was finally able to get a reading from my 9000l/h flow sensor. I have the flow sensor installed before a UV sterilizer off a manifold and currently all the water is going through the sensor before entering the display tank. The pump I’m using is a Varios8 rated at 2700gph. So tell me why the flow sensor is giving me a reading of 450gph with the Varios8 on max power. I know some pressure is lost due to the plumbing, but that much?? Am I doing something wrong!?
