Hello friends, is there any rule of thumb for calculating a minimum flow for an inverter controlled centrifugal pump?
How could one determine this value? My confusion comes from this: given a frequency you can probably find the minimum flow by restricting the outlet valve and watching for noise/temperature. But then again, you could just reduce the frequency without closing the outlet valve and achieve the same flow reduction...
