How do you use a Multimeter to find how much water is in a 5 quart pail of ice cream?
Answer:
You could use probes to measure the resistance (of the water) and painstakingly calibrate your multimeter reading against the resulting water level. Not very reliable, and highly dependent on salinity and other minerals in the water.
Since you ask ".how would YOU .", well, I would use a floater on an arm that swivels on the shaft of a potentiometer, whose resistance thus changes with water level height, which I can read on a multimeter.
let me take a guess... in a 5 QUART pail of ice there are umm 5 QUARTS! or 160 ounces or 1.25 gallons
