摘要：
The invention concerns an installation for measuring and displaying protected against risks of being frozen, comprising a fluid metering assembly (1) connected to a fluid supply pipe (2) and a fluid outlet pipe (3). Said fluid metering assembly (1) is mounted in an inspection window (4) below the frost line, said pipes extending in a trench produced in the ground (13) and connected to the inspection window (4). The metering assembly (1) is removable with or without interrupting pressurised fluid. A metering plate (8) retains flexible junction means (9, 10) connecting the intake and the outlet pipes (2, 3) to the metering assembly (1). The installation comprising the fluid metering assembly (1) is useful for maintaining protected against frost and accessible standard valves and fittings, in particular straight or coaxial meters (1).
