designed as such that very little heat is lost or gained through the outer cylinder.
Insulation
Where insulation is required a variety of materials may be used to insulate the meter. Care must be
taken not to insulate the meter above the halfway mark of the electronics support post as shown in the
sketch.
Do not insulate above
this line.
