13.2 Fuel throughput

With the fuel meter connected, the system calculates continuously the current fuel
throughput. The time required for calculating the fuel throughput varies and lies between
1 and 10 seconds. If the fuel meter delivers no pulses for more than 10 seconds, the
display shows "0" fuel throughput. This means that when fuel throughput is at its mini-
mum, the sensor should have a pulse frequency of at least 0.1 Hz. The display is
smoothed to improve the settling process. With fuel throughput at its maximum, the
maximum frequency is 300 Hz.

13.2.1 Configuration

Calculation of fuel throughput is configured based on the pulse valency of the connected
fuel meter.
No. Parameter
128 Fuel meter: Pulse valency (pulses / unit of volume)
When the pulse valency is set to 0.00, the display shows "0" throughput.

13.2.2 Reading out the fuel throughput

The current fuel throughput can be read out via the following parameter on the service
menu:
No. Parameter
960 Fuel throughput in unit of volume / h (m³/h, l/h, ft³/h, gal/h)
Display of fuel throughput is possible up to 6553 units of volume / h.
Note
Display of fuel throughput up to a value of 99.9 on the service menu is made with one
decimal place, from 100 with no decimal place.
