Airmar DFM-300-DA SmartFlex Diesel Flow meter, 50-300LPH

SmartFlex Diesel Flow Meter, 50-300 LPH, Dual-Chamber, Alloy housing, Threaded connections.

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)

Features

• Lower overall cost due to differential sensor capabilities
• Ease of installation with optional accessory kit
• Automatic Temperature compensation
• Simple set up using the SmartFlex View software embedded in the Airmar SmartFlex or SmartBoat module
• Fuel never comes in contact with gears or other parts that might clog or corrode
• The sensor is digital – specialized wiring isn’t required – plug and play to the SmartFlex or SmartBoat Module for data delivery to the display.
