18 VSD module 22.05.2018
18.1.7 Fuel meter readings
The VSD module ascertains the cumulated gas or oil throughout. For each type of fuel,
there is 1 resettable and 1 nonresettable meter available.
When resetting the fuel meters, the reset date is stored.
The system continuously calculates the throughput of the selected type of fuel. The
calculation time is dynamic and reaches from 1 to 10 seconds.
If the meter delivers no pulse for 10 seconds, the throughput displayed is «0». This
means that with minimum throughput, the sensor’s pulse frequency should be a minimum
of 0.1 Hz.
The display is smoothed.
The maximum frequency is 300 Hz when fuel throughput is at its maximum.
