4.7 Heating and insulation
There are several ways to heat the meter. In most cases heating is unnecessary as the meter
is 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.
Electrical Heating
Electrical tape heating may be used. Care should be taken to only heat the sections where the
best effect will be achieved. Do not heat above the converter mount centre line See illustration.
