First Ever Fuel Flow Sensor MFlow T ex by Jeti
Look what just showed up, first ever Fuel Flow Sensor. Made by Jeti, MFlow T is first ever true fuel flow sensor. It will be coming in 2x versions, one for Jets and one for Gas/Glow applications.
For people who do not use Jeti DC/DS-16 radios, you still can take advantage of this sensor. Jeti ProfiBox with MFlow sensor and Jeti R3 transceiver (Receiver) can be used as independent telemetry.

Sweet product. Great Innovation. Obviously Jeti is tuned in to what the eccentric jet guys are looking for.
I love my 18mz ... but ... I could see lugging up an additional RX and the shirt pocket box to get real fuel monitoring.
When will this be available?

how much time do you spend looking at your tx while flying? what is the point of knowing how much fuel you are using just before it hits the ground because you were looking at useless info

I don't spend any time looking at my Tx while flying. I fly with a Jeti DC-16 which has voice output of telemetry, alarms, and even switch positions.
The spotter/caller can also use a JetiBox Profli if desired. It gives the telemetry of up to 20 items of data (in addition to the data displayed/voiced by the transmitter.

Jeti isnt stupid and neither are those who buy their products. A friend of mine has the Jeti and his telemetry is just unreal. Voice prompts for just about any threshold you can think of, including battery life. The new fuel flow sensor will enable a fuel remaining warning at whatever level you desire.
So you see, this and similar products actually enhance safety because they eliminate guessing about critical values.

well the new high dollar radios all have audio and vibrations that can be set to predetermined voltages, airspeed and fuel. Plus at events you have a spotter for radio call outs.

The setup is very simple. Just set your Alarm for let's say 4000ml and have system give you voice/sound information when you need it.
You can also assign custom Voice announcement "Tank 30% left" to any level you desire.
Also with "Live" monitoring of fuel consumption, many people are surprised how small change in they throttle management can effect fuel consumption. I have noticed that going from 70-90% of the power had almost NO effect on speed, but fuel consumption went up by 50%.

Yesterday I attended the 25th Anniversary Arizona Jet Rally (many thanks to CD Bob Ruff and the Mesa club for a great event) and tested the MUI-30 that I installed between the ECU and fuel pump of my Reaction. The plane has a 3.8 liter (128 oz) fuel tank and a JetCat P160SX. The timer is set for 7 minutes (gear up to gear down). Typically there is about 30 oz left after a flight but, if I've had a bit of a "lead foot" during a flight there isn't much fuel left so I've been hesitant to change the timer.
The first two flights, I used the timer and put in "normal" flights with a wide range of throttle settings. There was about 30 oz left and the telemetry said the fuel pump had consumed 350 mAh and 352 mAh. For the next flight, I set an alarm ("Bingo Fuel") at 400 mAh as a signal to land and ignored the timer. After taxiing back to the pits, the pump had consumed 419 mAh and there was about a 1/2" of fuel (~15 oz) left in the tank. This seemed a bit too little for comfort so I changed the alarm to 380 mAh which I figured should leave about 3/4" of fuel left in the tank at the end of the flight.
The fourth flight was flown with extended periods of low-mid throttle settings. At about 9 minutes, the 380 mAh alarm sounded, I dropped the gear and landed. The fifth flight had extended periods of full throttle and the 380 mAh alarm sounded at about 6 minutes. After both flights, there was about 3/4" of fuel left in the tank.
I also had set up an alarm to play a wav file saying "Flameout Flameout Flameout" if the fuel pump amperage dropped below 0.1 Amps. I've seen lots of cases, particularly at busy events when you can't hear your engine, where it has taken a pilot 5-10 seconds to realize he has flamed out and was barely able (or unable) to make it back to the runway. Fortunately, the flameout alarm was unused yesterday though I'm sure I may hear it sometime in the future and it perhaps will make the difference between bringing the plane home in one piece versus in a garbage bag.
Indeed, yesterday another pilot ran his tank dry in flight. Fortunately the plane was close and he heard the engine stop and was able to make it back to the runway. Lucky...this time.
I'm extremely pleased with the performance of the MUI-30 used in this application. It costs only $38, gives an accurate reading of fuel state, an alarm if the turbine should flameout, and monitering of the ECU battery voltage. That's a lot of added safety for a very low price.

Jim

This is not a first. Fuel flow for Multiplex has been available since January 2011

I thought the voice telemetry was awesome when it first came out, and even wanted a Jeti because of it. Then I flew next to a guy who had it and I landed cause it was just too much and ruined my flight experience. I think hearing your stuff is fun, but its like having a neighbor that plays his bass way too loud. I hope people who use these become conscious of this and use earphones if possible. my .02

You know you can assign the voice activation to the Switch or Accelerometers, touch the switch or tilt radio and you will hear the voice/music.....or whatever you like.
There is also option of setting up alarm, only if preset condition is met the voice is activated.
I have set up mine on 3- position spring loaded switch, UP telemetry, Down timer voice.

Prompts every minute or so wouldn't bother me, but this radio sounded like a broken record. It was giving altitude every 10 seconds or so. I hope the bad first experience hasn't ruined me. Like I said I hope people can just be aware that as cool as it is, the guy next to you wants to fly his own airplane.

However by activating the "Auto-Judge" feature (available on firmware revision 4.1.14), when ever the GPS telemetry indicates the maneuver was at least an 9.5 out of 10 the earplugs are bypassed and a wav file is played over the speaker saying "Awesome maneuver, way to fly!" This is useful to let your buddies know just how great a job you are doing.

Jim
P.S.: Just kidding (if you hadn't figured that out from the firmware revision/date)
