Maintenance: The Lumax Electronic Flow Meter has been designed to require a
minimumamountofmaintenance.Theonlymaintenancerequiredarethefollowing:
1. BatteryChange
2. Cleaning of the Turbine
1. Battery Replacement: The Lumax Electronic Flow Meter comes complete with
2x1.5V.AlkalineBatteries(SizeAAA).LumaxElectronicFlowMeterfeatures
twolow-batteryalarmlevels:
a. WhenthebatterychargefallsbelowtherstlevelontheLCD,thexedbatterysymbolappears.Inthiscondition,
Flow Meter continues to operate correctly, but the fixed icon warns the user that it is advisable to change the batteries.
b. If Flow Meter operation continues without changing the batteries, the second battery alarm level will be reached
which will prevent operation. In this condition the battery icon starts to flash and is the only icon that remains
visibleontheLCD.TochangetheBatteries,withreferencetotheexplodeddiagrampositions,proceedasfollows:
• PressRESETtoupdateallthetotals
• Loosenthe4screwsonthebackcover

Malfunctions
4. Direct modification of K Factor: This procedure is especially useful to correct a “mean error” obtainable on the basis of several performed dispensing operations. If normal Flow Meter operation
showsameanpercentageerror,thiscanbecorrectedbyapplyingtothecurrentlyusedcalibrationfactoracorrectionofthesamepercentage.Inthiscase,thepercentagecorrectionofthe“USER”K
Factormustbecalculatedbytheoperatorinthefollowingway:
NewKFactor=OldKFactorx(100-E%)
100
If the meter indicates less than the real dispensed value (negative error) the new calibration factor must be higher than the
old one as shown in the example. The opposite applies if the meter shows more than the real dispensed value (positive error).

Example:
ErrorpercentagefoundE% -0.9%
CurrentCalibrationFactor 1,000
New“USER”KFactor 1,000*[(100–(-0,9))/100]=
1,000*[(100+0,9)/100]=1.009

WARNING!:
Do not discard the old batteries in the environment.
Refertolocaldisposalregulations.
2. Cleaning:
Only one operation is necessary to clean the Flow Meter.
AfterremovingFlowMeterfromtheplantwhereitwas
built in, any residual elements can be removed by
washing or mechanically-handling. If this operation
does not restore a smooth rotation of the turbine, it will
have to be replaced.
WARNING!:
Do not use compressed air onto the turbine in order to
avoid its damage because of an excessive rotation
