Fuel Return Flow Sensor

Fuel Return Flow Sensor


A Fuel Return Flow sensor is used to monitor the amount of fuel flow returning to the tank. It is most commonly combined with a Fuel Flow sensor to exactly calculate the fuel being consumed by the engine by measuring the fuel flow before and after the fuel injectors.

Fuel Return Flow Sensor Configuration




This node is used to calibrate the Fuel Return Flow sensor. The flow rate unit can be configured in Preferences > Unit Options.

Display



This node sets the display settings for the Fuel Return Flow channel. 
Warning Maximum - Sets the flow rate at which the Fuel Return Flow sensor Number Displays, Gauges and Bars will enter their lower warning state.
Warning Maximum - Sets the flow rate at which the Fuel Return Flow sensor Number Displays, Gauges and Bars will enter their upper warning state

Diagnostics



This node allows the enabling of high and low voltage/frequency DTCs for the Fuel Return Flow sensor.

A DTC severity can be set for each voltage/frequency, which will trigger an Engine Protection level for the relevant setting.

Wiring



This node configures the wiring for the Fuel Return Flow sensor, as well as selecting the input type.

Select 'Analogue - Voltage' if the Fuel Return Flow Sensor to be connected produces a 0-5V signal. This sensor generally has the Pull-Up disabled.
Select 'Digital - Frequency' if the Fuel Return Flow Sensor being connected produces a frequency signal.
