Is that POUNDS per minute x 1000? Like you could read out that you're burning 100,000 pounds of fuel per minute?

PPH is Pounds Per Hour. The F100-PW-220 likes her gas, but not THAT much.

Ahh, it's an H and not an M... Got it.

Gene,

What kind of signal does this thing take? I was just thinking about building a gauge that can be calibrated with a 0-5v signal.

Serial. The controller is an Arduino Nano that drives both the OLED display and the H-Bridge chip that controls the air core motor for the needle.

I keep a couple of OLED modules around for arduino project displays...they can be had cheap on ebay, easy to interface, and take practically no power.

It's easy to use one of the analog inputs on an Arduino as a voltmeter input, if that's what you need for your project. https://www.google.com/search?q=arudino+voltmeter
