local fields - Conductors of Weil-Deligne representations

Suppose $(V,N)$ is an $n$-dimensional semisimple $WD$ representation of $W_{mathbb{Q}_p}$. This corresponds under local Langlands to an admissable representation $pi$ of $GL_n(mathbb{Q}_p)$. Is there some simple way to "read off" the conductor of $pi$ from the corresponding $WD$ represention $(V,N)$?
