ACOUSTIC HOUSING FOR TUBULARS
First Claim
1. An acoustic housing, comprising:
- a cover comprising a first perimeter defining an open cover portion, and having a cover length and a cover height; and
a body comprising;
a second perimeter defining an open body portion configured to receive one or more electrical components and to sealingly engage with the first perimeter, the body having a body length, a body height, and an under-surface, at least one of the first perimeter and the second perimeter comprising a first chamfered perimeter and a second chamfered perimeter, respectively; and
an engagement portion projecting from the under-surface and having an engagement length, an engagement height, and an engagement surface configured to engage an outer surface of a tubular.
