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.
