- the installation for measuring and visualizing the volume of fluid has been placed between the pipes 2, 3 forming a portion of the pipe, thus the fluid passes through the counting assembly 1 fixed and indexed in depth frost-free on the plate 8 look 4.
- the fluid arrives and leaves the counting assembly 1 by the flexible tubes 9, 10 which are coiled in the form of turns 22 of large diameter in the low position.
- the direct reading dial of the counter is facing upwards. This allows the volume consumed to be read without raising the counter.
- the depth indexing of the plate 8 stopping the counter from the frost height. So, at the minimum depth, it is possible to view the volume by leaving the counter 6 in the frost-free position in the manhole 4.
- the counting assembly 1 is raised at the same time as the plate 8. As the counting assembly 1 rises, the diameter of the turns 22 decreases.
- the maximum upward stroke of the counting assembly 1 is stopped by the outlet limiter system 23 which maintains the minimum radii of curvature of the turns formed by the flexible connecting tubes.
- the outlet limiting system 23 of the metering assembly maintains the minimum radii of curvature of the turns formed by the flexible connecting tubes.
- Maintaining the fluid flow in the high position of the metering assembly 1 allows access to the operating meter, in particular for recording the volume consumed, maintenance and changing of parts, taking a water sample for analysis. , to check the correct functioning of the meter and of the fittings, such as the non-return valve, and to set up an anti-fraud protection system such as sealing.
- the outlet limiter system 23 prevents the flexible joining means 9, 10 from falling to the bottom of the manhole 4.
- the counting unit 1 is locked by the fixing means 24 for temporary attachment to the upper part of the manhole 4.
- the counting unit 1 is lowered in the manhole 4 until the means d indexing provided for the lower position of the counting assembly 1 at the frost-free depth.
- the diameter of the turns increases during the descent which produces the erasure of the counting assembly 1. This avoids twisting the flexible tubes 9, 10 and housing them in a well under the manhole 4.
