Airmar SmartFlex Diesel Flow Meter, 50-300 LPH, Dual-Chamber, Alloy Housing, Threaded Connections - DFM-300-DA
Part #DFM-300-DA
MFG #DFM-300-DA
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 CES 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.
