4 OPERATION
Note : When the system is in programming mode, the metering device will continue to
operate with the previously set values, i.e. it can still be operated with the binary inputs
whilst in programming mode. However, the reset values are only taken into consideration
when the programming mode has been quit.
To do this, the reset values are sotred and a Reset function is performed, i. e. if a fill process
is currently in operation, it would be interrupted.
4.4.1 The Fitting Factor Multiplier (Fig. 4)
Since the display only permits values to be set between 0 and 199.99, a multiplier is
introduced. If this is set to x10, this means that the adjustable value is multiplied internally
by 10. If, for example, the fitting factor has been set at 10.45 , the value set is actually 104.5.
The multiplier is not display in standard mode.
4.4.2 The Fitting Factor (Fig. 6 and Fig. 8)
The fitting factor (K) adjusts the 8020 sensor's blade wheel to the electronic system of the
metering unit. The fitting factor indicates how many pulses the blade wheel emits per
volume flow. The volume unit for the fill quantity is determined by the fitting factor and does
not therefore have to be given in addition. Any unit can be used (ml, l, m
4.4.3 The Fill Quantity Multiplier
The fill quantity multiplier can be set in the same way as the one for the fitting factor.
4.4.4 The Fill Quantity (Fig. 6)
The fill quantity determines the quantity to be filled or metered. Its unit is determined by
the fitting factor. If the fitting factor is recorded in pulses per lotre, then the fill quantity is
automatically expressed in litres.
Example :
Pipeline of nominal diameter of 25, made from PVC (fitting factor 46.60)
Fill quantity : 300 litres
The following values are set :
