CommissioningProline Promass 83 Modbus RS485Calculation type "% MASS 2D" or "% VOLUME 2D"For this type of calculation, the relationship between the two variables concentration and referencedensity must be known (2-dimensional), e.g. by a table. In this way, the concentration can becalculated from the measured density and temperature values by means of the following formula(the coefficients A0, A1, etc. have to be determined by the user):K=A0+A1· +A2· +A3· +A4· 2 3 4 ref ref ref refK Concentrationref Currently measured reference densityA0 Value from function (COEFFICIENT A0 (7032))A1 Value from function (COEFFICIENT A1 (7033))A2 Value from function (COEFFICIENT A2 (7034))A3 Value from function (COEFFICIENT A3 (7035))A4 Value from function (COEFFICIENT A4 (7036))a0004621!Note!Promass determines the reference density by means of the density and temperature currentlymeasured. To do so, both the reference temperature (function REFERENCE TEMPERATURE) andthe expansion coefficients (function EXPANSION COEFF) must be entered in the measuringsystem.The parameters important for measuring the reference density can also be configured directly viathe "Commissioning" Quick Setup menu.Page 78 • MN0M030Issue/Rev. 0.2 (12/12)
Proline Promass 83 Modbus RS485Commissioning6.4.2 Advanced diagnostic functionsChanges to the measuring system, e.g. coating buildup or corrosion and abrasion on the measuringtubes can be detected at an early stage by means of the optional software package "AdvancedDiagnostics" (F-Chip, accessories ä 87). Normally, these influences reduce the measuringaccuracy of the system or may lead to serious system errors.By means of the diagnostic functions it is now possible to record various process and deviceparameters during operation, e.g. mass flow, density/reference density, temperature values,measuring tube damping etc.By analyzing the trend of these measured values, deviations of the measuring system from a"reference status" can be detected in good time and corrective measures can be taken."Caution!!Note!Reference values as the basis for trend analysisReference values of the parameters in question must always be recorded for trend analysis. Thesereference values are determined under reproducible, constant conditions. Such reference values areinitially recorded during calibration at the factory and saved in the measuring device.Reference data can also be ascertained under customer-specific process conditions, e.g. duringcommissioning or at certain process stages (cleaning cycles, etc.).Reference values are recorded and saved in the measuring system always by means of the devicefunction REFERENCE CONDITION USER (7401).It is not possible to analyze the trend of process/device parameters without reference values!Reference values can only be determined under constant, non-changing process conditions.Methods of ascertaining dataProcess and device parameters can be recorded in two different ways which you can define in thefunction ACQUISITION MODE (7410):• PERIODICAL option: Measuring device acquires data periodically. Enter the desired time intervalby means of the function ACQUISITION PERIOD (7411).• SINGLE SHOT option: The user himself acquires the data manually at different, free selectableperiods.Ensure that the process conditions always correspond to the reference status when data is beingrecorded. It is only in this way that deviations from the reference status can be clearly determined.The last ten entries are retained in chronological order in the measuring system.The "history" of such values can be called up via various functions:Diagnosis parametersMass flowDensityReference densityTemperatureMeasuring tube dampingSensor symmetryOperating frequency fluctuationTube damping fluctuationData saved (per parameter)Reference value REFERENCE VALUE functionLowest measured value MINIMUM VALUE functionHighest measured value MAXIMUM VALUE functionList of the last ten measured values HISTORY functionDeviation measured/reference value ACTUAL DEVIATION functionMore detailed information can be found in the "Description of Device Functions" Manual.Issue/Rev. 0.2 (12/12) MN0M030 • Page 79
