User Buttons:
Lumax Electronic Flow Meters features Two Buttons (RESET and MENU) which individually perform
two main functions and together, other secondary functions. The main functions performed are:
- “
RESET” Key: Resetting the Partial Register and resettable TOTAL
(
RESET TOTAL)
- “
MENU” Key: Entering Calibration Mode.
Used together (Press both Buttons for 5 Seconds), the two keys permit entering Configuration mode, useful for changing the units of measurements and calibration factor.
Battery Housing:
Lumax Electronic Flow Meter uses two standard 1.5V power Batteries (size: AAA). Battery Housing is easily accessible - simply loosen four screws on the back of the Device.
Caution:
Make sure you remove the
Batteries very slowly and carefully to ensure that any damage to the Wires, Connections, or the LCD Display Card is avoided.
Installation:
The inlet and outlet for the Flow Meter is 1“ NPT. It can be easily connected to a Pipe or Nozzle. It can be installed in any desired position and is suitable for stationary or mobile applications.
Do not use a wrench to install the meter. Hand tighten only.
Tip:
To extend the life of the device, it is recommended to install a filter on inlet side of the meter.
1. Daily Use:
The only operation that is necessary for daily use are, partial and/or resettable total register resetting. Occasionally the meter may be necessary to be configured or calibrated. For this,
please follow the instructions in this manual. Below, are the two typical display figures displayed in normal operation.
Figure on the left denotes the Partial and the Resettable Total registers. The figure on the right
denotes Partial and Non-resettable TOTAL. Resettable total amount adds to non-resettable TOTAL
amount automatically. This is preset at the manufacturing plant and cannot be modified.
NOTE:
6 digits are available for Totals, plus two icons x 10 / x100. The increment sequence as follows:
0.0 - 99999.9 - 999999 - 100000 x 10 - 999999 x 10 - 100000 x 100 - 999999 x 100
Dispensing in Normal Mode:
Normal mode is the standard dispensing. While the count is
made, the partial and resettable total are displayed at the same time: Reset Total
(Fig. 1)
.
Should one of the keys be accidentally pressed during dispensing, this will have no effect.
A few seconds after dispensing has ended, on the lower register, the display switches from
Resettable TOTAL
to General
TOTAL: the word Reset above the word TOTAL
disappears, and
the
RESET TOTAL
is replaced by the General
TOTAL
(Fig. 2)
. This situation is called standby
and remains stable until the user operates the Flow Meter again.
Partial RESET:
The Partial Register can be reset by pressing the RESET
key when the meter
is in standby, meaning when the display screen shows the word “TOTAL”
(Fig. 3)
.
After pressing the RESET
key, during reset, the display screen first shows all the lit-up digits
and then all the digits that are not lit up
(Fig. 4)
.
At the end of the process, a display is first shown with the RESET
Partial and the
RESET
Total
(Fig. 5)
and, after a few moments, the
RESET TOTAL is replaced by the Non-Resettable Total
(Fig. 6)
.
Resetting the RESET TOTAL:
The
RESET
TOTAL
resetting operation can only be performed after
resetting the partial register. The
RESET TOTAL
can in fact be reset by pressing the
RESET
key at
length while the display screen shows
RESET TOTAL
(Fig. 7)
. Schematically, the steps to be taken are:
1.
Wait for the display to show Normal Standby display page - with total only displayed
(Fig. 8)
.
2.
Press the
RESET
key quickly
3.
The meter starts to reset the Partial
4.
While the display page showing the RESET TOTAL
is displayed
(Fig. 9)
. Press the
RESET
key
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
“
RESET TOTAL
”
(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)
:
* the dispensed partial
* the Flow Rate in [Partial Unit / Minute]
Procedure for entering this Mode:
- wait for the Remote Display to go to Standby, meaning the display screen shows TOTAL
only
- quickly press the MENU key.
- Start dispensing
The Flow Rate is updated every 0.7 seconds. Consequently, the display could be relatively unstable at lower Flow Rates. The higher the Flow Rate, the more stable the displayed value.
IMPORTANT
-
The
Flow Rate is measured with reference to the unit of measurement of the Partial. For this reason, in case of the unit of measurement of the Partial and TOTAL
being different, as in the example shown
below, it should be remembered that the indicated Flow Rate relates to the unit of measurement of the partial. In the example shown, the Flow Rate is expressed in Qts/min. The word “Gal” remaining
alongside the Flow Rate refers to the register of the Totals (Reset or NON Reset) which are again displayed when exiting from the Flow Rate reading mode
(Fig. 12)
.
To return to “Normal” mode, press the MENU key again. If one of the two keys RESET or MENU is accidentally pressed during the count, this will have no effect.
Important:
Even though in this mode they are not displayed, both the
RESET TOTAL
and the General Total (
TOTAL
) increase. Their value can be checked after dispensing has terminated, returning to
“Normal” mode, by quickly pressing MENU key.
Partial RESET:
To reset the Partial Register, finish dispensing and wait for the Remote Display to show a Flow Rate of 0.0 as indicated in the illustration then
quickly press RESET
(Fig. 13)
.
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-set default factor. It is equal to 1,000. This calibration factor ensures utmost precision in the following operating conditions:
Fluid:
Diesel Fuel
Temperature:
20°C (68°F)
Flow Rate:
10-120 litres/min. (2.65-31.75 Gal.)
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?:
When operating close to extreme conditions, such as for instance with fluids close to acceptable range extremes (like Diesel Fuel at Low Temperatures) or in extreme Flow Rate
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.
