Super User Rate Totalisers Our Rate Totalisers are a reliable and accurate, low cost way to monitor important fluid movements. When used in conjunction with a suitable flowmeter, they can provide power free indication of instantaneous flow rate, total flow and accumulated total to maximise efficiency and reduce waste. Available options include: Field Mounted, Loop Powered, Intrinsically Safe, Analogue Input, 202D Field Mounted Rate Totaliser Contrec The 202D Field Mounted Rate Totaliser requires no external power and is designed to operate with turbine, positive displacement and paddle wheel flow meters.
