TOTAL A
1.6 CONTRACT HOUR
The contract hour can be set to any hour of the day in steps of 1 hour.
When the system clock reaches the time set in
Contract hour:
●
the
Current Day Total
is copied to the
Previous Day Total
.
●
the
Current Day Total
measurement is then restarted (reset to zero).
Clock, the clock will be interrupted if there is a power down. When the unit is
powered up again, the operator will be prompted to enter the correct system
time.
If the clock is not initialized, all measurements and calculations are done as
normal. However, when the Daily Total feature is enabled, detection of
Contract hour and the updating of Current day total and Previous day total will
not be done at the correct time.
1.7 CURRENT DAY
TOTAL
Shows the amount/volume of totalized product since the last contract hour.
This a ‘running’ totalizer and cannot be reset to zero.
See
Section 4.4.3: Current day total and Previous day total [»13]
for
information on reviewing more day totals.
1.8 PREVIOUS DAY
TOTAL
Shows the amount/volume of totalized product between the last contract
hour and the contract hour before that. This totalizer cannot be reset to
zero.
See
Section 4.4.3: Current day total and Previous day total [»13]
for
information on reviewing more historical day totals.

MENU 2: FLOWRATE A
First set up the flowmeter in
SETUP
6: FLOWMETER
as this directly affects the settings/measurement
units in this menu (
Flowrate
).
If the type of flowmeter unit is changed in
SETUP
6.6: FLOWMETER > UNITS
or
6.7: FLOWMETER > UNIT
, the
units in
2.1: FLOWRATE A > UNIT
will change to the default setting of the selected flowmeter.
If the settings in
SETUP
2.1: FLOWRATE A > UNIT
,
2.2: FLOWRATE A > TIME
, or
2.3: FLOWRATE A > DECIMALS
are
changed, this will directly affect the analog output settings in
7.3: ANALOG OUTPUT > RATE MIN (4MA)
,
7.4: ANALOG OUTPUT > RATE MAX (20MA)
, and the displayed bargraph in
5.7: DISPLAY > RATESPAN
.
Therefore, you should first determine the required settings for the flowrate.

FLOWRATE A
2.1 UNIT
Determines the measurement unit for the flowrate. The type of unit that can
be selected depends on the flowmeter unit (volumetric or mass) selected in
6.6: FLOWMETER > UNITS
.
The following can be selected:
AUTO-VOL: mL - L - m3 - US GAL - I GAL - cf - Oil bbl - nL - nm3 - scf
AUTO-MAS: mg - g - kg - ton - lb - US ton
Hand: mL - L - m3 - US GAL - I GAL - cf - Oil bbl - nL - nm3 - scf - mg - g -
kg - ton - lb - US ton - rev - P - (no unit)
2.2 TIME
Determines the time interval (sec, min, hour or day) for calculating the
flowrate.
2.3 DECIMALS
Determines the number of decimals for the flowrate.
2.4 K-FACTOR
This value is used to convert the flowmeter pulse signals to a flowrate unit.
The
K-factor
is based on the number of pulses generated by the flowmeter
per measurement unit selected in
2.1: FLOWRATE A > UNIT
.
The more accurate the
K-factor
, the more accurate the system.
This setting can only be changed if the automatic unit conversion in
6.6: FLOWMETER > UNITS
is set to Hand. Otherwise, K-factor conversion will be
Auto.
After pressing PROG, the decimal point will start to flash. The decimal
position can then be changed by pressing the SELECT-key, then press the
CLEAR key to set the digits.
