There are instruments called Ceilometers which can measure cloud height and cover, but they're not especially accurate for cover (they are quite good for cloud height, especially at night) as a cloud can sit over the instrument and give a false reading. Also, unless cloud passes over them they give a false negative. The best instrument for measuring cloud cover is a trained Mark I eyeball (or two).

A nephoscope is an instrument used to measure the height, direction, and velocity of clouds. It works by reflecting sunlight off the cloud and measuring the angles of reflection to determine cloud characteristics.

This instrument doesn't exist; visibility is measured with the eyes, having some landmarks for comparison.
