Belite Fuel Level System

[skippydiesel]

I am having problems getting my Belite fuel level sensing system to work.

 

I would like to make contact with any users who failed or succeeded to install this system.

 

I am trying to send the sensor/black box (module) signal to a Dynon Skyview.

 

I am also intersted in tracking down the brand & part number of the sensor. My sensor has no legible brand and the  part numbers are only  partially legible, so take the following numbers with a big grain of salt:

 

• 631C-002M-G-1-C

If it is the stickon type plastic sensor they are either a serial data out of a open collector transistor

Thanks for the try Kyle  - this is what the sensor looks like:

 Fitted in/on the bottom of the fuel tank - This is the part that I need details on.

 

The sensor feeds into a  calibration box;

 The calibration box is connected to my Dynon

Thats probably a 4-20ma sender. Is there any numbers on the sender?  some are 0.5 to 4.5V analogue style though

The Belite system is working in my Sonerai. My sensor (pressure transmitter) is from GaMicos model GPT200 (0-0.2 bar) and it feeds a UMA capacitive gauge. I didn't want to drill a hole for a sensor in my fuel tank and have the transmitter installed at the tap outlet. I know nothing about a Dynon Skyview but the output from my transmitter is 0-4.75 volts.

 

I also had trouble getting it working and had to calibrate 4 or 5 times. In a state of elderly confusion I had misconnected the circuit and blew up the first transmitter and controller box. I then ordered a second one and got it working. I have tested the transmitter and controller box seperately since and both were faulty.

Lettering/numbers very faint - could be 

• 631C-002M-G-1-C

Specifications etc -https://www.radiantinstruments.com/product/radiant-fuel-probe-system

 

0.5-5.0V output (range?)

Thanks Cosmicray - that's great information.

 

Not very reassuring about the transmitter and controller box - did you have it replaced under warranty?

[Kyle Communications]

If you hook it up wrong I doubt it would be replaced under warranty....thats not in any manufacturers pervue

Fair comment however if Cosmicray is able to demonstrate a faulty stem (aside from his faulty installation) I would expect an honourable supplier to do something for him.

No - I bought a new system. I connected incorrectly so it was my problem.

[skippydiesel]

So no fellow Belite Fuel Level users out there???

too expensive

 

[skippydiesel]

 

The following references might just get the attention of the more tech savvy and I hope a recommendation for a second (preferably low cost ) sensor.

My son (mainly) & I have worked out most if not all of the deductions contained in the above.
We think we know what the solution is (a second pressure sensor T'd off the tank breather) BUT not sure of the most cost effective way of achieving this ($263US + delivery from Aircraft Spruce is a tad steep for a sensor )

Agree; can't beat sight tubes and mark one eyeball; plus the savannah collector tank and its low fuel sensor.

So you have a philosophical objection to assisting?

[facthunter]

I doubt you could justify that inference. It can be difficult.  Nev

Fully justified - I am seeking some technical advice/input from those who are talented in the filed of electronics, not unhelpful comments on cost & alternative fuel level assessment systems. Besides being unhelpful, could be construed, by a more sensitive soul, as being a put down.

[facthunter]

I agree we don't need put downs.  Nev

Skippy its called research..if you went and found out how the sensors worked and usually with some searching of google images you will see how to hook up the sensor. You re trying to set it with a dynon skyview...wouldnt it make sense to ask Dynon for some guidance?..if they cant give you any then its up to you to see if you can sort it out. It may not be possible due to the way Dynon does its inputs. You will then need to see what ADC is used for the Dynon inputs or if all their gear is CAN bus or RS232...dont know. I would have to do the required research to make it all hook up just like I am suggesting you do. You are trying to do something that is not normally done so you have to make your own roadmap then

Thanks Kyle - I think you will see from my earlier post (repeated below) that the research has/is being done - the cause of the problem pretty well nailed (fluctuating tank pressure) however a cost effective solution (second sensor for tank fuel surface pressure) eludes us.

seems totally unsuitable for shallow un baffled fuel tanks that are subjected to continuous movement.

[Thruster88]

You may be better off just going to a capacitance type sensor that is compatible with Dynon.

Maaate!!

 

Your comment doesn't address the issue. 

 

The problem is not to do with fluid (petrol) agitation, its all about in tank pressure, which you would know if you had any experience with the system OR had bothered to read even some of the information I supplied OR my own comments on the matter.

 

FYI - I am a well aware that technologically older, possibly easier to install/work with, systems are available. If I cant get this one to work as hoped, I will certainly review the alternatives.

The belite system using pressure is to me an example of shit engineering in the modern world. Low on fuel? Just pull 2 g's and you will have twice as much.

[Blueadventures]

its all about in tank pressure  -  this is the issue you will not solve.
