Technical Data
frequency inputs / gasoline pulses 6.5.1.
The volumetric flow of the delivered gasoline is measured by the piston
meter, converted into a frequency-proportional clock signal by the
gasoline pump computer and switched to the frequency input of the
controller (
Fig. 4: ).
In the controller this clock signal is processed as the actual value of
the volumetric flow of the gasoline.
High-level pulse: 3.4 V – 26 V
Low-level pulse: 0 V – +0,9 V
Input resistance: > 10 k Ω
Max. input current: 5 mA
Min. pulse duration: 400 µs
Measurement rate:
1 measurement/0.75 s
Resolution: 1 Hz
Measuring range: 0 ... 51 l/min
Pulse rate: Can be adjusted via manual control unit from
31 – 200 pulses/liter
