Cubic metres or litres.
In liters
In the metric system, the Gram, as in kilogram is the standardfor mass measurement
Litres for a domestic aquarium, kilolitres for a large [public] aquarium.
Since water towers generally have a very large capacity, I would say that cubic meters might be the best bet. You can measure the total volumetric capacity of the water tower in cubic meters and then determine the volume of water that is currently in the water tower. However, an amount of water can also be measured in liters.
Mililiter
Efficiency variance can be a good metric because it measures how efficiently inputs were used to produce output.
gallons
Aquasana Water Filters is the best house water filter system and it reduces the amount of lead in the water.
It measures the amount of oxygen in the exhaust stream. The computer uses that info to adjust the amount and timing of the fuel injection system to achieve the best emissions, power, and fuel economy.It measures the amount of oxygen in the exhaust stream.

Personally, I would use metric measures, but if you still use Imperial measures, then 1 inch to 1 mile is best.
If you think about it for a moment, depth is a measure of length, so of the four units provided only miles and meters are used for length. Ounces and gallons are US measures of fluid capacity.
