Parameter settings for an accurate in-/outflow and pump capacity calculation
Function
• Calculatetheinowusinglevelchangepertimeunittimes
surface area
• Calculatethepumpcapacityeverytimeonepumprunsbyitself
• Pumpcurves,rpmcompensationandsystemdatacanbe
enteredformoreexactcalculation
• Apumpmonitoringsequencecanbemanuallyinitiatedviathe
pump status menu
Value
• Avoidwastingenergyusingpumpswithdegradede󰀩ciency
• Servicepumpbeforebreakdown
• Servicecanbeplannedtooccurduringnormalworkinghours
• Noexternalowmeterrequired
Pump and system curves
• Pump curves can be entered
• Thesystemcurveiscalculatedfromtheonlinemeasurement
togetherwithgivendataforstatichead,totalheadandowatgivendutypoint.
• Thesystemcurvedoesnotneedtobeenteredifamainspressuresensorismounted,onlythe
heightdi󰀨erencebetweenpumpinletandpressuresensorhas tobeentered!
Pump capacity monitoring and pumped volume recording via an external flow
signal
Function
• Pumpedvolumeandpumpcapacitycalculationcanbedoneusinganexternalowmeter
• Theinternallevel/volumebasedcalculationforinowcanbecombinedwiththeexternalowsignal
Logging of pumped volume
• Continuous accumulation over time
• Daytotalforlast7days
• Canbecombinedwithenergymeasurementforpumpe󰀩ciencycalculations
• Canbeusedforcomparingowsbetweenstationsinacollectionnetwork,pinpointingpossible
problemsofwateringressoroverowswithinthecollectionsystem
