Fuel Flow Monitor
Part #: FFM100-01

Maretron's FFM100 provides precision fuel flow information to help optimize fuel consumption, which can save thousands of dollars in fuel operating cost. The FFM100 uses state-of-the-art, positive displacement metering technology for unprecedented accuracy. In fact, the accuracy of the FFM100 is nearly that of commercial vessel systems costing tens of thousands of dollars, yet the FFM100 cost less than existing recreational systems found on the market today. Additional benefits of the positive displacement metering technology are the elimination of flow conditioning components such as straighteners and pulsation dampers. Other flow meter technologies require flow conditioning components that increase system and installation cost. The FFM100 also uses true temperature compensation with embedded temperature sensors within the meters. The returning fuel is generally hotter than the supply fuel and if not properly compensated, inaccuracies as much as 5% can occur in computing the engine's fuel consumption. The FFM100 also detects momentary reverse flow in the fuel lines due to fluctuating pressure caused by the injection pump. Less accurate systems count the reverse fuel flow as part of the consumed fuel where the FFM100 properly accounts for momentary reverse flow.
Lastly, the FFM100 can be used for fluid types other than fuel (e.g., water, oil, etc.) by ordering the appropriate flow sender.

The FPM100 is NMEA 2000® certified so you can view any and all information anywhere on the vessel using a compatible NMEA 2000® display. The FFM100 is a key component of Maretron's N2KView® vessel monitoring and control system.

Features:

  • FFM100 converts a variety of flow senders (e.g., fuel, water, etc.) to NMEA 2000® Network Data
  • All flow senders ordered separately depending on application (i.e., single fuel flow sender for gas engine, dual fuel flow senders for diesel engine, water flow sender for sea water, etc.)
  • Fuel flow senders facilitates fuel consumption optimization for reduced fuel operating cost
  • Fuel flow senders use positive displacement metering technology for superior accuracy over other measurement technology such as turbine meters
  • Fuel flow senders do not require costly fuel conditioning components like flow straighteners and pulse dampers
  • Fuel flow senders implement true temperature compensation with precision built-in thermistors for increased accuracy
  • Fuel flow senders automatically detect reverse flow due to fluctuating pressure difference from injection pumps
  • Fuel flow senders pass particle sizes up to 70 micrometers (diesel fuel filters normally filter down to 2 micrometers to prevent clogging injectors)

Very Different, But Works Well
This is built much different than the others. It has a foam seal around the edges. The filter portion is standard, but the carbon activated material is a setoff beads suspended between a screen a honeycomb structure. There is air freshener built-in to help with the smell in the car. Fits well in my 2015 RAV4. Just as easy to install as any other filter. The price is on the high side so with this one I am hoping to get at least one year of use from it.

Well-Made Carbon Cabin FIlter
I love the honeycomb carbon filter on this cabin filter. It looks like it will do an excellent job cleaning the air in my car. It came in a cardboard box and was easy to install and fit my Toyota well. I would have appreciated some arrows on it, like other filters come with, to let me know I was inserting it correctly. I just followed the example of the one already in my car. If you accidentally take that one out first, you may not remember which side goes where. So, my improvement would be arrows on the filter itself. Otherwise, the airflow seems great, it functions well and seems to be a great quality!

Use activated carbon to clean the air naturally!
This is a serious air filter with activated carbon inside of it and I'm here for it. I use little activated carbon bags in my car already as an air freshener because I hate those fake chemical scents from the little trees or from the car wash. The chemicals in those fake scents give me migraines. I absolutely love the idea of putting the active carbon in the cabin air filter itself to clean the air. This fits prefecture in my 2017 toyota prius v. It was just a easy to install as any purge cabin air filter. The hardest part is opening all the parts of the glove box to get the old one out. This filter seems sturdier than my last one and it's a good value for the money.

Perfect fit for 2016 Corolla!
Fit's my 2016 Corolla perfect. Has a sturdy frame. Other name brand ones I have purchased before don't have the sturdy frame and squish up. This comes with tiny fragrant beads on the top part and has a light fresh scent when the air is on. Very happy so far.

Good fit, good value
Style: CF12436 Classic, Style: CF12436 Classic
Purchased this filter for my 2023 Outback. First off changing the cabin filter on this model Subaru is amazingly easy and can be done with no tools and no more then 5 minutes. Pictures posted show packaging, the paper "Blue" filter side, the "Black" charcoal side and the foam outer edge. The filter is well made and is very sturdy as the outer shell is plastic vs. other paper filters that are more flexible. Holding the filter in your hand and giving it a slite shake you can hear the activated charcoal within it. After installing the filter I had a few trips in the car, did I notice any difference in the air quality coming into the cabin....... no. But does this mean its not working? also no. What I can say is the filter fit snug and left no gaps, and with the plastic surroundings and foam in sure the filter will not be letting anything get by as it passes through the system. All and all this filter is well made and sturdy, and seems to be a good value with other paper only filters being about the same price.
