Reliability and Continuous Improvement - CiES

Non-Contact Fuel Level Measurement

Recently we ran across an article in the Cirrus Owners Magazine  - Cirrus Pilot 

The article talks about the Continuous Improvement Process that Cirrus Aircraft utilizes in its aircraft design and production to improve reliability.

This article it discusses the complete paradigm change CiES made to aircraft fuel level measurement and Cirrus Aircraft's customer satisfaction with our non-contact fuel measurement technology.

As the article states - CiES Brought a Whole New Approach to Aircraft Fuel Level.  

An approach that changed fuel level reliability, so significantly, that it is no longer necessary to question your aircraft fuel level indication.

Take Your Fuel Level Indication to Un-Charted Territory and  Embrace the Reliability of the CiES Non-Contact, Magnetic Field, Fuel Level Solution

Turboprop Fuel Level Indication


We are consistently being tapped by new product development teams in aviation for Turboprop fuel level indication. 

Aircraft and Rotorcraft Manufacturers are finding that CiES provides high quality fuel quantity indication systems.  
Fuel Quantity Suite - Temperature Compensation - Automatic Switching  

Our system is so accurate that we provide fuel quantity switching for single engine aircraft that utilizes fuel tank quantity as the only sensor system utilized to balance fuel tanks.   That's right - no more switching tanks on the 1/2 hour, it is now accomplished automatically on many of the platforms we are now serving.


Our digital fuel level technology utilizes modern sensors to detect fuel level or ullage boundary and output the either the native digital information or convert the digital signal to an analog output for use in legacy aircraft platforms.  Our consistent high quality performance indicates that our signal is not degraded with fuel type, fuel contamination, fuel temperature or entrained air.

In fact we accomplish this without any electronics in the fuel volume.


The high technology sensor combined with a simple mechanical system is patented by CiES for measuring fuel level.   Our demonstrated quality output, illustrates our effectiveness in fuel measurement. 


The fact that our fuel indication system is finding its way onto so many new Jet A platforms shows that CiES offers an uncommon value in aviation.

The CiES fuel quantity solution represents both a higher quality and a more cost effective solution than  traditional Jet A fuel quantity systems  --- We are worth looking into.

CiES Mooney Fuel Level Senders - A Digital Fuel Sensor with Analog Outputs

Today we delivered 2 sets of CiES Mooney Fuel level senders for late mode M, R, S, & TN Mooney aircraft.

So we now have fuel level senders for the popular Mooney Bravo, Ovation, Eagle & Acclaim. 

We are now adding a new aftermarket general aviation platform every week.  

In addition CiES is adding a new OEM or commercial application every month.

Unique to CiES Fuel Level Senders:

  • Set 1 - was set up for a Mooney Bravo with a voltage output for interfacing to a JPI 900 
  • Set 2 - was set up for a Mooney Acclaim with a resistive output for the factory G1000 system.

CiES has the unique capability of supporting multiple platforms with the same sender design.  This sender design physically plugs into the same mounts in the aircraft.

While the float remains - CiES's method of measurement is lightyears away from the traditional potentiometer or resistive sender of the past.   CiES senders utilize a patented magnetic field technology that has more in common with the digital compass in your flight instrument or your cellphone.

Like a compass that always points north, the CiES fuel level sender always points to the float.  The sensor is precise enough to measure the angular position of that float down to tenth's of a degree and that precision is repeatable over time, temperature and vibration.

Beechcraft Bonanza Fuel Level Senders

We just completed our first set of Beechcraft Bonanza Fuel Level Senders

These magnetic field senders are for Tip tanks produced by a popular Beechcraft modification facility.

We are starting to branch out into multiple applications in the aviation field with our magnetic field fuel level senders, from turboprop, helicopter or piston aircraft. 

Our technology allows for a nearly plug and play solution for legacy resistive fuel level sender installations.

What started as a Cirrus Aircraft only application for fuel level sensing is slowly starting to spread across the aviation field.  With over 10,000 senders produced to date,  CiES is "The Word" in aviation fuel level sensing.

Ask us about your application?

Turboprop Fuel Level Senders - Digital

Bull Aircraft - Digital Fuel Level 

This  will be the first of many announcements we are allowed to make before the end of May 2015.

Another customer is added to the list.   Bull Aircraft manufactures a turboprop utility plane the Explorer.  

Bull Aircraft Website

We manufactured our new TSO Senders for this kit built aircraft providing a universal sender for every location. These senders incorporate fuel temperature probes to provide - Lbs. or Kilo's Fuel as this is a Jet A Application utilizing the Walter M601 Turbine.

We are interfacing with a VR Avionics MFD and we expect to see an interesting interface for fuel level.

Both,  Bull Aircraft and VR are Experimental - but the senders for this aircraft are FAA TSO Approved.

We think this aircraft will be sucessful.

Cardinal Flyers Organization Digest - Sun & Fun

FROM THE Cardinal Flyers Organization DIGEST 

JP Instruments, the engine monitor folks, shared that they continue to work with CIES, a friend of CFO's, who have introduced a superior design fuel level transmitter.


The JPI930 certified engine instrument replacement already works with the CIES transmitter in native mode, frequency domain.


The JPI900 certified engine instrument replacement works with the CIES transmitter in voltage or current mode.

CiES Inc 177 Fuel Senders 
Several Cardinal owners have already ordered the CIES transmitters to improve repeatability and accuracy of their fuel level measurements, while reducing installation cost and fuss, and hopefully achieving longer term reliability.

The Three Fundamental Truths About Aircraft Fuel Level

We have a unique perspective to aircraft fuel level,  in that CiES works daily on these systems.  We see the good, the bad and the downright ugly.

What we have observed and are sharing here is what CiES has determined to be the

Three Fundamental Truths about Aircraft Fuel Level Systems. 

Here they are:

If the technology of fuel level measurement can find the surface of the fuel reliably. 
    • Floats that actually float or are allowed to float.
    • A set capacitance based on fuel level in a tube (ignoring temperature & other fuel dielectric effects).
    • Ultrasonics tend to get messed up with foaming fuel. 
If the basic sensor system can output a lot of data related to fuel level. 
    • A capacitance fuel level system can output a theoretically infinite number of data points - but realistically in an actual fuel level device -  potentially 10,000 to 30,000 data points 
    • Our Magnetic Field Technology has 10,000 to 12,000 data points.
    • A legacy potentiometer system that provides maybe 50 or 60 data points (wiper and trace size controlling the data point size) 

If your fuel level display system can capture the complexities of a fuel tank curve  
    • a non linearly marked fuel gauge or an Multi Function Display with a calibration feature

Then if these three criteria are met - you will have an excellent aircraft fuel level system - meet a few of them and your fuel level system will be functional. 

As we know the world isn’t perfect -  

To make a old aircraft fuel level system work well -  You need to make a unique potentiometer, carefully assemble it to reduce internal friction, maintain wiper contact and hope it all holds together and doesn’t corrode.  

Now combine the above with a non linear and an easy to calibrate gauge.  This is fussy work at best.


Here is  our real world challenge  - 

  • Say for example you have a simple fuel gauge marked with the same distance from Empty to 1/2 tank, & from 1/2 tank to full 
  • We are all very familiar how long it takes to go from Full to 1/2 Tank and that it takes a fraction of the time to go from 1/2 Tank to Empty.
    • The above is a fundamental universal truth. 
  • Therefore because CiES can  - we load a tank table with a characteristic curve onto internal memory on the sender.
    • Log, Sine, 3rd order, 4th order, 5th order, Non Linear - You name it - We can do it - challenge us.
    • Of course we need the tank function and a simple gauge to get it right.
  • Unlike a potentiometer - we don’t have to cram all that onto a circuit card by physically making the small steps with variably positioned traces, or onto a carefully delineated gauge.
  • We have 10,000 reliable data points with our sensor technology - we just do it in software - easy peasy. 

Just don’t tell me that fuel gauges only have to be accurate at empty - we get all apoleptic.
