This innovative little box helps aircraft owners calibrate irregular or circular fuel tanks, providing a linear fuel level from a fuel tank that is in no way linear. It acts as an ‘interposer’ between the tank, fuel probe, and instrument display.
 
It provides the same benefit of fuel tank calibration found in EFIS systems. 
 
Although not designed for panel mounting, it does include a five-point LED fuel gauge. The output of the FLC may be attached to any standard fuel gauge. A Fuel Pressure Sensor is available separately,

  • For calibration, five buttons are set at 0, quarter, half, three-quarter, and full levels. The input into the FLC may be any standard 0 to 5 volt fuel probe or any standard resistive sender.

     

    The output of the FLC is always a standard 0 to 5 volt value, compatible with almost all fuel gauges currently on the market. Furthermore, the FLC includes a five-point LED fuel level gauge, which illuminates red when the tank remains below 25% of fuel.

     

    It is an affordable option that helps solve tank and probe calibration issues. Although not designed for panel mounting, it does include a five-point LED fuel gauge. The output of the FLC may be attached to any standard fuel gauge.

     

    We also make a Fuel Pressure Sensor available separately,

To Our Customers

We are in the business of offering innovative aircraft instruments for experimental aircraft flying, and backup / CO instruments for general aviation (non-TSO/non-PMA). The instruments from Radiant Technology are not designed to be used in applications where their failure would endanger safe flight or human life in any way. They are intended solely for use in VFR conditions. They are not certified to meet any Technical Standard Order, and are not produced under a Parts Manufacturing Authority (TSO / PMA). As a result, they are suitable only for use in experimental and ultralight aircraft, and in Light Sport Aircraft, if meeting the requirements of the respective manufacture.

Support

If you need support for your Radiant instrument purchase, please contact us by email at support@radiantinstruments.com. Because of our small staff, we do not have a direct phone number.  We do our best to respond to emails as soon as possible. If you do not hear from us within 48 hours, please try again. You may also try kathy@radiantinstruments.com. Please check our our Warranty Information here.

Shipping Information

Since we offer innovative aircraft instruments, we often introduce new products for sale that are in the final engineering phase. Sometimes an engineering problem emerges in the final phase that delays our production runs. This means that if you are ordering a new product, we could be several weeks out from shipping. We try to keep our product pages up to date with shipping information.

​

As of 2025, there are only two of us working Radiant instruments. We manufacture products in batches, and cycles take about a month. It is always best to order now and get on the list. We do charge your card at the time your order is placed.

 

We are now able to offer 2nd day UPS shipping on domestic orders, as well as USPS Ground Advantage. In some cases, we may need to revise you shipping amount, and will notify you by email of that change.
