Tank
Depending on Daqu channel configuration and Emsis layout, tank
can work in one of two modes:
software tank — tank simulation,
hardware tank — based on real measurements from sensors.
7.1
Software Tank
The software tank is active when no fuel level channel is configured
in Daqu. Emsis allows you to enter the current amount of fuel and
this amount is then reduced in time based on fuel consumption. The
fuel consumption is either calculated or measured. Measured fuel
consumption usually gives better results assuming that a high quality
fuel flow sensor is applied. If fuel flow sensor is not applied, then the
fuel flow is approximately calculated based on the engine type.
As you can see, the fuel level of software tank is highly subjective
and depends on:
initial estimate of fuel quantity,
precision of the fuel flow sensor or precision of the fuel flow
mathematical model.
Furthermore, any error in fuel flow will sum up in time resulting in
a
significant error
in fuel level indication. This means that software
tank level indication must be accepted with scepticism and the pilot
should not rely only on this indication.
When software tank is active, selecting the
Tank
item from the
Emsis
Setup
screen displays the
Set fuel
window, figure 31. Use the
up
and
down
buttons to adjust the fuel level.
Alternatively, you can long press on the
screen selection
button.
This opens the same window.
