For those of you with the grandrapids eis for rotax 2 cycles,



what options do you have?

can the two aux. inputs be used for fuel level?

anyone using the fuel flow option, altimeter?



I have two 45 litre aluminum tanks that only have a clear fuel line to read the level.  They are behind the passenger seat and very hard to see. I would like to put a skysport fuel sending unit in each one but before I buy a fuel guage as well I would like to know if the eis can read fuel level. I know alot of people like the standard needle guages but I find them hard to read (accurately). I've decided to replace them with an eis (not sure what one yet). I find that with the guages that I have, I am guessing as to what it is reading because the needle travel is so smalll.I would much prefer a digital number especially for the more critical readings. 



Anyone else with a different eis such as a stratomaster please don't hesitate to comment on your unit.



Thanks,



Tony

Call Grand Rapids Tech. and they will tell you exactly what you need.

  

 They sell the Prince capacitive fuel level sender, which I highly  recommend.  Yes, ties into Aux.  Will also do altitude.

  

 Best customer service>

He is correct, and the Prince fuel sender is a good one, but  there is only one aux wire on the two stroke EIS that will work as a fuel  sender. I used two senders with my two stroke EIS by getting a double pole,  double throw switch and wired the switch so that one direction read the front  tank and the other direction read the back tank. I also had the tanks isolated  and selected between them with a selector fuel valve, so that when you changed  tanks you also changed the switch. It has worked quite well for me for more than  6 years.

That's exactly what I want to do... thanks for the info. What length does the sender come in and can it be cut down (I need about 22")... or is it a resistor swing type?

Your best bet is to call Grand Rapids, you will talk to  Sandy who is so knowledgeable that several guys have proposed to her over the  phone, including me.  She can fix you up with what ever you need. There are  several sizes of senders, I used the 12 inch one with my stock  tanks.

Anyone out there with a stratomaster? The grandrapids eis seems to be very popular.

Here is web site info for the EIS unit - note there are 2 stroke and 

4 stroke models as well as 2 and 4 cylinder models.



http://www.grtavionics.com/product.aspx?productno 



http://www.grtavionics.com/product.aspx?productno &featureno=8



http://www.grtavionics.com/product.aspx?productno &featureno 6



According to their web site info for the EIS-2002 (2-stroke, 2 

cylinder model) it has two user configurable aux inputs, I would take 

it these both can be used for fuel level sensors.  You need to ask if 

they remain available if you elect to have the altimeter/vertical 

speed option or fuel flow option.  It can be ordered with those 

options.  I have the fuel flow option on mine, works great.  I use it 

to cross check fuel remaining and my fuel level.



Check their warranty policy - its says a lot - I have my second unit 

and like the first (on another plane) it has been rock solid.  I am a 

very happy user of their product.  My next plane will also have one 

of their units..

jerb
