Lumax LX-1371 User manual
Electronic Flow Meter
Thank you for purchasing Lumax®Electronic Flow Meter. Please read this Operational Manual carefully. It is important that you read the
entire manual to become familiar with the unit before you begin assembly and/or operate the unit. Lumax Electronic Flow Meter is ideal
for metering the transfer of fluids. It is simple and easy to use. It can be installed in-line or at the end of the delivery hose before the nozzle. Using precision turbine measuring technology, Lumax
Electronic Flow Meter measure liquids
accurately and conveniently. Large 1” (25mm) LCD display can be calibrated in Gallons, Quarts, Pints and Liters. It has an easy-to-read five-digit LCD dis
play
for accurate readings while dispensing fluids, with a Totalizer (resettable) to track total usage. The display can be rotated at any angle which simplifies the reading in any position. Field replaceable
batteries provide power and are easily accessible - simply loosen four screws on the back of the unit.

Resetting the RESET TOTAL: The RESET TOTAL resetting operation can only be performed after
resetting the partial register. The RESETTOTAL can in fact be reset by pressing the RESET key at
length while the display screen shows RESETTOTAL (Fig. 7).Schematically,thestepstobetakenare:
1. WaitforthedisplaytoshowNormalStandbydisplaypage-withtotalonlydisplayed(Fig. 8).

again for at least 1 second
5. The display screen again shows all the segments of the display followed by all the
switched-off segments and finally shows the display page where the reset
“RESETTOTAL” (Fig. 10) is shown.
Dispensing with Flow Rate Mode Display: It is possible to dispense fluids,
displaying at the same time, as shown (Fig. 11):

2. Calibration
Definitions: Calibration factor or “k factor”: Multiplication factor applied by the system to the electrical pulses received, to transform these into measured fluid units.
FACTORY “K FACTOR”:Factory-setdefaultfactor.Itisequalto1,000.Thiscalibrationfactorensuresutmostprecisioninthefollowingoperatingconditions:
Fluid: Diesel Fuel Temperature:20°C(68°F) Flow Rate:10-120litres/min.(2.65-31.75Gal.)
Even after any changes have been made by the user, the factory k factor can be restored by means of a simple procedure.
USER K FACTOR: Customized calibration factor, meaning modified by calibration.
Why Calibrate?: Whenoperatingclosetoextremeconditions,suchasforinstancewithuidsclosetoacceptablerangeextremes(likeDieselFuelatLowTemperatures)orinextremeFlowRate
conditions (close to minimum or maximum acceptable values), an on-site calibration may be required to suit the real conditions in which the Flow Meter is required to operate.

Calibration Procedure: The Lumax Electronic Flow Meter permits making quick and precise electronic calibration by changing the calibration factor (k factor). There are 2 dif
ferentwaysofcalibration:
1. On-site calibration, performed by means of a dispensing operation. 2. Direct calibration, performed by directly changing the k factor.
To enter the calibration phases it is necessary to press and hold down the “Menu” button.
Whyenterthecalibrationphases?
• Displaythecurrentlyusedcalibrationfactor • Returntofactorykfactorafterapreviouscalibrationwithuserkfactor
• Changethecalibrationfactorusingoneofthetwopreviouslyindicatedprocedures.
In calibration mode, the partial and total dispensed quantities indicated on the display screen take on different meanings according to the calibration procedure phase. During the calibration, the Flow
Meter cannot perform any normal dispensing operations. In calibration mode, the totals are not increased.
Caution: The Lumax Electronic Flow Meter features a non-volatile memory. It keeps the calibration and dispensing
data stored even after replacing new batteries or long periods of inactivity.
3. Display of Current “K Factor” and Restoring “Factory K Factor”:
BypressingtheMENUkeywhiletheapplianceisinstandby(PressButtonfor3Seconds),
the display page appears showing the current calibration factor used. If you are using the Flow Meter with
“factory k factor”, the display page shown in the diagram will be displayed, with the word “fact” (Fig. 14).
Ifone“userkfactor”hasbeenset,thecalibrationfactorsetbytheuser(inourexample0.998)willbedisplayed.
The word “user” indicates a calibration factor set by the user is being used (Fig. 15).
The Flow chart alongside shows the switchover logic from one display page to another. In this condition,
theResetkeypermitsswitchingfrom“User”factorto“Factory”factor.
To confirm the choice of calibration
factor,quicklypressMENUwhile“User”or“Fact”aredisplayed.Aftertherestartcycle,themeterusesthe
calibration factor that has just been confirmed.
Attention:Whenthe“FactoryFactor”isconrmed,theold“UserFactor”isdeletedfromthememory.
In-field Calibration: This procedure calls for the fluid to be dispensed into a graduated sample
containerinrealoperatingconditions(FlowRate,Viscosity,etc.)requiringabsoluteprecision.
WARNING:

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).

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
