C'mon Jerry. Don't you have any compassion for Ward's lip? I put this discussion behind me until I have something concrete to support my claims. Here's three basic and fairly inexpensive ways I know of to measure fluid levels. 1. mechanical - The dipstick for measuring the oil in your car. 2. electronic - The variable capacitor (or resistor) in your car's gas tank. I don't know if that's been updated or not. 3. optical - A light source on one side of a container, and a receiving unit on the opposite side.
I believe any other systems would be more sophisticated and costly. Keep the fires burning. "I'll be back".
