3.5 Installation


CAUTION!
It is essential that you comply with the local health and safety
regulations in force for installing flange connections.

CAUTION!
Fitters for flange connections in countries in which the Pressure
Equipment Directive applies must have an appropriate
qualification (e.g. under EN 1591-4).

CAUTION!
We recommend fitting a cone strainer with a mesh size of 250 µm
to protect the meter. When installing the meter in a vertical
position, with the direction of flow from bottom to top, a strainer
must be fitted to both the meter inlet and outlet (to protect against
falling dirt).
Remove the cone strainer again after around 4 – 6 weeks since it
may be saturated after this time and therefore will inhibit the flow.

CAUTION!
Only install gas solenoid valves downstream of the quantometer.
