The phrase "a depth gauge" is correct and usable in written English.
It can be used when referring to a tool or instrument that measures the depth of a substance, such as water or soil.
Example: "The diver used a depth gauge to ensure he did not exceed the safe diving limit."
Alternatives: "a depth meter" or "a depth measuring device."
A depth gauge read 110 feet.
Every few feet, they stuck a depth gauge into the water.
