Measuring liquid level in barrels
I have to find the amount of liquid contained in bsrrels if hazardous waste. I used to use a tape measure to guess the height of liquid... Not very accurate but cannot use a dip stick due to the nature of the chemicals.
This month I remembered the LIDAR in my iPhone and sought an app that would simply measure distance from the phone to the nearest surface. This works great and now I just remove the bung and place my iPhone camera over the hole to read the distance to the top of the liquid. Pretty accurate, too
A coupe of tips:
Clear liquids are tricky.
Angle the camera toward the center of the drum or it sees the inside wall of the barrel.
Doesn't like when the liquid is sloshing about.
