Product Data Sheet00813-0100-4005, Rev BAOctober 2009Rosemount Flow ComputerExpand the Capability of Flow Measurement TechnologyExpand CapabilitiesSteam Mass FlowThe Rosemount Flow Computer satisfies theinstrument requirements for a variety of flowmetertypes in liquid, gas, steam and heat applications.Multiple flow equations are available in a singleinstrument with many advanced features.Flow ComputerEasy To UseThe alphanumeric display offers measuredparameters in an easy to understand format. Manualaccess to measurements and display scrolling issupported.VersatileFlowmeterThe versatility of the Flow Computer permits a widemeasure of capabilities within the instrumentpackage. The various hardware inputs and outputscan be “soft” assigned to meet a variety of commonapplication needs. The user “soft selects” the usageof each input/output while configuring the erSteam Net HeatFlow ComputerWaterAdaptabilityThe isolated analog output can be chosen to followthe volume flow, corrected volume flow, mass flow,heat flow, temperature, pressure, or density bymeans of a menu selection. Most hardware featuresare assignable by this method.SteamFlowThe user can assign the standard RS-232 Serial Portfor external data logging, transaction printing, or forconnection to a modem for remote meter reading.Simplified VerificationA Service or Test mode is provided to assist the userduring start-up system check out by monitoringinputs and exercising outputs. The system setup canalso be printed.FlowmeterPressureTemperatureTransmitter TransmitterLiquid Delta HeatT2TemperatureTransmitterWarmFlow tter
