Compensation for limited float range
Posted: Mon Jun 23, 2014 7:21 pm
Hi folks,
I am finishing up an RV 8. 21 Gallon tanks, EIS 4000 GRT Hx system. I calibrated the fuel tanks over the weekend. Started seeing float movement at about 1.5 gallons. Stopped moving about 17.5 gallons. I programmed per the GRT instructions and all is well except that it show full as 17 gallons. If I enter the capacity on the EFIS at 21 gallons, then the bar graph looks 3/4 full when the tanks are full. Someone on VAF said that they set this up so that the capacity is listed as 21 gallons. It indicates full until the float starts moving at 18 gallons. I clearly need to have the 21 gallons in the system to get the fuel totalizer to work properly, so this seemed like the right thing to do.
Anyway, anyone know how to do this? How to set up the HX or EIS to indicate full at 21 gallons until the float moves? Is there a better idea or how to program this?
Regards,
