Currently looking at replacing original fuel gauges, in a C182P (c.1974).
Has anyone experience of these resistive gauges from AeroSpace Logic? I’m not convinced that float-type senders can be accurate
enough in bladder tanks. Perhaps more sense to research accurate fuel-flow kit?

You may want to take a look at this short video from one of our customers. Both senders and our instrument are covered under our EASA STC.
Thanks
@Aerospace_Logic rather than just posting an advertisement, can you answer the question in post #1?
We have hundreds of customers flying bladder tanks with float type senders and our instruments. The combined system can easily provide +/- 1USG and better accuracy with the CiES sender. The calibration process maps the fuel level relative to sender and bladder movement to create a specific, one-of, performance curve for each tank.
I got it wrong in post #1, as A-Logic don’t use resistive senders, so I’d be seriously interested to know whether their ‘magnetic field technology’ would perform OK with our bladder tanks. We’d like to delay replacing the tanks as our budget has a few other priorities to deal with.
Edit 1- our posts crossed – thanks, will be in contact.
Edit 2 – I’m curious to know how one calibrates float-type senders – in the cruise? On the ground? I’ll get hold of the installation manual.
Fuel tanks are always calibrated with the aircraft in level flight attitude, with the aircraft on the ground.
I think 2g was concerned about accuracy when the bladder has collapsed because it isn’t full. Does that happen? I don’t know if bladders are glued in place, or are just lying there.
This is a 182 with bladder tanks that I calibrated new CEIS senders recently with a Garmin EIS. The bladders don’t collapse as the tank empties.
Can you use the orignial Cessna fuel guage senders with these?
