SUPERtrol II Flow Computer213.11 Liquid Sensible HeatMeasurements:Actual volume flow is measured by the flow element (DP transmitter, Flowmeter).Temperature is measured by the temperature transmitter. A pressure transmitter can beused to monitor pressure. Pressure measurement does not affect the calculation.Calculations:• The density, mass flow and sensible heat are calculated using the fluid characteristicsstored in the flow computer. (see "FLUID DATA" submenu)Output Results:• Display ResultsSensible Heat, Mass or Volume Flow Rate, Resettable Total, Non-ResettableTotal, Temperature, Pressure, Density (optional: peak demand, demand lasthour, time/date stamp)• Analog OutputSensible Heat, Mass or Volume Flow Rate, Temperature, Pressure, Density,Peak Demand, Demand Last Hour• Pulse OutputSensible Heat, Mass or Volume Total• Relay OutputsSensible Heat, Mass or Volume Flow Rate, Total, Temperature, Pressure Alarms,Peak Demand, Demand Last HourApplications:Calculate the energy stored in a condensate with respect to water at 32°F (0°C).LIQUID SENSIBLEHEATLiquid Sensible HeatIllustrationVolume FlowAs calculated in section 3.8Heat FlowHeat Flow = C • volume flow • (1-α • (T1-Tref))2 • ref. density • (T1 - 32)α = Thermal expansion coefficient • 10-6C = Specific heatCalculationsFlowmeter TemperatureTransmitterPRINT50 –TIMECLEAR•MENUENTERHELPTEMP4PRE 13RATE2TOTAL1GRAND6SCROLL7PRE 28DENS9OptionalPressureTransmitter T1 |
