Haow To Measure The Temparature Of Revolving Ball Mill

Net vs Gross Flow — LIQUID (also applies to total volume) Gross Flow = volumetric flow rate at actual conditions (‘observed’) — what most flow instruments measure Net Flow = volumetric flow rate converted to flow rate at standard conditions — usually 60 deg F WHY NET To keep consistent — measure flow at 20 deg F then product heats up to 40 deg F — different observed amount.
