Medium pressure meter installation kits for flow rates not exceeding 6 m3 h-1
|Publication Date:||1 April 2019|
This Specification covers product requirements for medium pressure (MP) meter installation kits.
Note: As purchased, a kit excludes the meter and meter box, but provides a method of providing a connection from the outlet of an emergency control valve (ECV)/filter to the inlet of a meter and provides an appropriate method of sealing the meter outlet/connecting to the consumer's pipework.
The pre-assembled kits are designed to fit into meter boxes:
• wall mounted
• built in
• universal, or
where there is a MP supply terminated by a ball valve with a male outlet to BS EN ISO 10806 and mating cap or a legacy ECV/filter.
Note: The kits may be installed in other types of housing, e.g. brick built, provided the requirements of BS6400-2 are satisfied.
An installed kit will provide:
• nominal 21 mbar metering pressure, and
• capacity of 6 m3 h-1, and
• a range of outlet pressures that is compatible with standard European appliances.
Note 1: Details on the installation of medium pressure gas meter installations is given in BS 6400-2.
Note 2: European appliances.
