Digital Tank Instrument and Engine Monitor Recommendation

[MichaelG]

Can anyone recommend a tank instrument and engine monitor to:

- get the precise fuel amount that is in the tank

- get engine data as well as fuel flow data

What is a good choice for that purpose?

Certified as primary to replace factory engine and fuel level gauge, full color engine monitor/fuel totalizer and fits in a standard 3-1/8" hole.

Many like the Cies senders, and the JPI engine monitors but, at least for an engine monitor, there are many other choices, such as EI.

Most of us have either a JPI 900/930 or the Electronics International version.

In order to use the fuel tank quantity to replace what your factory gauges show, you will need to have an instrument that qualifies as a “primary” instrument.

When I had my JPI 900 installed, I let the factory tank fuel senders. As you might surmise, I got the same sloppy indications on the 900 as I did with the factory gauges. That all changed with the CiES sender replacements. Those senders, combined with a primary fuel gauge, are spot on. The only thing better would be if the 900 displayed fuel in tenth increments. It rounds up or down to the next whole gallon. If you look at the raw data from the 900, you will see the decimal formal of fuel in the tank and fuel used. Pretty impressive.

As for fuel flow, I have dialed in my fuel flow by spending some time tweaking the transducer calibration. My fuel totalizer (the JPI 900) will typically be within 0.5 gallon of fuel consumed. And some of that error is caused by fuel expansion and contraction since my last fill up.

Insight or JPI, sorry but I’ve never been a fan of EI products.

Trust me, don’t believe ANYBODIES fuel quantity indicators, if they use floats, they can stick. Aircraft fuel tanks are hard to gauge I believe largely because they are so thin.

Use your fuel flow meter and keep a written amount on paper, or if you don’t have fuel flow use a calculated amount, but write something down with the time.

I’m not one to switch tanks every few minutes, on top of the hour is my method, but changing tanks every time you burn 4 or 5 gls is I think excessive 

If nothing else when the CB pops IFR you will know how much fuel you have left in each tank.

Many, many people have run out of fuel due largely I think because they trusted fuel gauges, of those that ran out a surprising number haven’t survived.

A very important part of any instrument or part is warranty and product support, as well as of course confidence they will still be around years from now.
