This course is designed for anyone seeking Initial CMET1 ACS Assessment or ACS Re-Assessment.
Range of scope for CMET1:
Primary meter installations incorporating diaphragm, or rotary displacement meters
without by-pass and of badged capacity > 6 m3/h ≤ 1076 m3/h and where the inlet pressure under normal gas supply conditions does not exceed 75 mbar and a meter regulator is to be installed.
This Assessment does not address meter installations that are not connected directly to and
downstream of the ECV, nor does it address those that are not adjacent to the ECV. Work on
such installations requires CMET2.
This Assessment does not address meter installations that are not Standard Designs, as
defined in IGEM/GM/6 Edition 2 except a by-pass is included. IGEM/GM/6 Edition 2 no longer
includes by-passes in its scope. New installations with a by-pass are covered by CMET2.
However, this assessment continues to include the safe operation of by-passes to address
