Notes:
1. Insulation Material: Rubber, Foam, Glass Fibre, or any other process suitable material.
2. Insulation must be firmly fixed to the pipework.
If especially desired by the customer, it is permissible to insulate the meter itself. If this is
required, then the following guidelines should be followed.
The insulation must be firmly fixed to the meter with no components such as straps or covers
that can vibrate (figure 11). DO NOT insulate converter (figure 12).

Important Note:
When insulating Ex meters, insulation must not rise above the square plate that connects the
sensor and converter (figure 12).

In addition, any heat tracing used (electrical or fluid) must not exceed 130°C for titanium meters
(optional 150°C). For zirconium meters maximum temperature is 100°C. The Ex temperature
