EXPLANATION OF SET-UP FUNCTIONS
IMPORTANT
The settings for Total, Accumulated Total and Flow rate are entirely separate. In this way, different units of
measurement and decimals can be used for each e.g. gallons for total and liters for flow rate.
1
Total/ Batch Total
1.1
Unit
This determines the measurement unit for Total and Batch total.
The following units can be selected:
L - m
3
- UKGAL - USGAL - UKbbl –USbbl - OILbbl
1.2
Decimals
This determines the number of digits and decimal points for total and batch total.
The following decimals can be selected (for 0, 1, 2 and 3 respectively)
0000000 - 111111.1 - 22222.22 - 3333.333
2
Accumulated Total
2.1
Unit
This determines the measurement unit for Accumulated Total.
The following units can be selected:
L - m
3
- UKGAL - USGAL - UKbbl –USbbl - OILbbl
2.2
Decimals
This determines the number of digits and decimal points for accumulated total.
The following decimals can be selected (for 0, 1, 2 and 3 respectively)
0000000 - 111111.1 - 22222.22 - 3333.333
3 Flow Rate
3.1
Unit
This determines the measurement unit for flow rate.
The following units can be selected:
L - m
3
- UKGAL - USGAL - UKbbl –USbbl - OILbbl
3.2
Time Period
This determines the time unit for flow rate
The following units can be selected:
/SEC (Second) - /MIN (Minute) - / HR (Hour)
3.3
Decimals
This determines the number of digits and decimal points for flow rate.
The following decimals can be selected (for 0, 1, 2 and 3 respectively)
0000000 - 111111.1 - 22222.22 - 3333.333
3.4
Calculation
The flow rate is calculated by measuring the time between a number of pulses, for
example 10 pulses. The more pulses the more accurate the flow rate will be. The
maximum value is 255 pulses.
Note:
the lower the number of pulses, the higher the power consumption of the unit will be
(important for battery powered applications).
Note:
for low frequency applications (below 10Hz): do not program more than 10 pulses else the
update time will be very slow.
Note:
for high frequency application (above 1kHz) do program a value of 100 or more pulses.
3.5
Cut-off
With this setting, you determine a minimum flow requirement thresh-hold, if during this
time less than XXX-pulses (setup 3.4) are generated, the flow rate will be displayed as
zero.
The cut-off time has to be entered in seconds - maximum time is 999 seconds (about 15
minutes).
4
Meter
4.1
*K-Factor
(Pulses per Litre)
With the K-factor, the flow meter pulse signals are converted to a flow rate. The more
accurate the K-factor, the more accurate the functioning of the system will be.
The setting allows a K Factor with up to 3 decimal places and 4 whole numbers e.g.
1234.123
*Please note that the K-Factor entered in 4.1 must be in pulses per litre (PPL). Entering the
k-factor in pulses per gallon (PPG) will result in inaccurate readings. Refer to page 8 for
detailed instruction on programming the k-factor.
