I know they make them because I have one,I have a few measuring sticks that were left here by delivery trucks.One of them has writing on the sides in gallons with the dimension of the tank on the side,don’t remember if it’s four different sizes or just two.
Son in law is a fuel salesman and I just asked him, he said as far as he knows now the outfit they buy sticks from only prints them in inches,says the tanks they supply have technology to let them know how much is in the tanks remotely.
