ldwilliams.uk Posted March 11 Share Posted March 11 Hi, I am looking to get the Alphacool ES flow and temperature indicator "HighFlow" with RPM-Signal https://shop.alphacool.com/en/shop/controllers-and-sensors/flow-sensor/17558-alphacool-es-flow-and-temperature-indicator-highflow-with-rpm-signal It has a conversion table for RPM to litres per hour which should be simple enough I would have thought, but the conversion ratio looks to change for each rpm given? How do I create an offset (think thats what is needed) and what would the offest be please anyone? Thanks Quote Link to comment Share on other sites More sharing options...
ldwilliams.uk Posted March 12 Author Share Posted March 12 I think that the ratio is 0.18 and the offset is -10 ? Quote Link to comment Share on other sites More sharing options...
