SmartFlex Single-Chamber Diesel Fuel Flow 
Meter
The SmartFlex™ single-chamber flow 
meters are designed for fuel consumption measurement of diesel engine systems 
with flow rates up to 4,000 L/h. Single-chamber models can be synched with other 
single-chamber DFMs (feed and return) for calculated fuel burn/consumption data 
for display on multi-function displays or Signal K interfaces.
Models are available with Alloy or Brass housings, with or without LCD window 
and threaded or flanged connections.
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)
 
  - 
  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.
