Flowphant T DTT31, DTT35Function and system designMeasuring principle80%DJvmA0023188The device measures the mass flow of a liquid medium using the calorimetric measurement method.The calorimetric measuring principle is based on the cooling of a heated temperature sensor. Heat isremoved from the sensor by forced convection due to medium flowing by. The extent of this heattransfer depends on the flow velocity of the medium and the difference in temperature between thesensor and the medium (King's Law). The higher the flow velocity or the mass flow of the medium,the greater the temperature sensor cooling.Measuring 3194A0005276Endress HauserSensingelementRTDRTDField ofapplicationMonitoring of the mass flow of water, waterlike substances and low-viscosity oils(viscosity: 0.184 to 20 mPa s; thermalconductivity: 29 to 688 mW/mK).

TheVarivent couplings enable flush-mount installation.Inlet and outlet runsThe thermal measuring principle is sensitive to disturbed flow conditions. As a general rule, install the measuring device as far away as possible from any flowdisturbances. For further information ISO 14511. If possible, install the sensor upstream from fittings such as valves, T-pieces, elbows etc. To attain the specified level of accuracy of the measuring device, the inlet and outlet runsmentioned below must be maintained at the very minimum. If several flow disturbances are present, maintain the longest specified inlet run.Endress Hauser11
