SmartFlex Dual-Chamber Diesel Fuel Flow Meter

The SmartFlex^™ dual-chamber flow meters are designed for fuel consumption measurement of diesel engine systems with flow rates up to 600 L/h. The flow meter measures fuel consumption in each line and computes the difference between supply and return. SmartFlex DFMs output NMEA2000^® to a T1 or T2 SmartBoat or SmartFlex Module*, for display on multi-function displays or Signal K interfaces.

Differential measurement of fuel consumption
SmartFlex dual-chamber DFMs have two measuring chambers for supply and return fuel lines. The flow meter measures fuel consumption in each line and computes the difference between supply and return.

Built-in battery
In case of the absence of an external power source, from the on-board network for example, the SmartFlex DFM keeps registering data to the internal memory. When external power is restored, all accumulated data will be transferred to the on-board monitoring terminal.

*SmartFlex DFM must be connected to a SmartBoat^® or SmartFlex T1 or T2 module.

DFM models provide data for fuel consumption including:

• Instant fuel consumption, L/H
• Hourly fuel consumption in “Forward” line
• Hourly fuel consumption in “Return” line
• Total fuel consumption, L
• Total fuel consumption in “Idling” mode of engine operation
• Total fuel consumption in “Optimal” mode of engine operation
• Total fuel consumption in “Overload” mode of engine operation
• Total fuel consumption in “Negative” mode of flow meter operation (return exceeds supply)
