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.

Works
It works to measure distances and it can be set to feet and inches
Great app! Very accurate
I use older cameras that require zone focusing. This has been an incredible tool to help me nail focus better. Very accurate! Highly recommend. Simple and doesn’t trigger those finicky AR modes most of these measure apps do.
Just point and get a reading.

Not Accurate
Nice concept but large discrepancy between fixed point and live measurements on iPad 12.9 Pro Gen 5. Suspect live measurement is incorrect. Just hold iPad still and toggle fixed point on and off to see difference.
Not really useful for me
Needs to come a bit further along in my eyes. It doesn’t look like you can fix two measuring points. What does that mean? Well when you start the app you get a little dot that you tell it to start at. Once you do that you do not get a second anchor point to get an accurate measurements. Basically you get nothing. Not even a crosshair to aim with. your measurement doesn’t hold the second your hand moves.
