Water meter chambers are compact, monobloc products (without joints or welds), made of polyethylene (PE), manufactured using rotomoulding technology. They are designed to protect the water meter and the service connection installation. Manufacturing conditions and general quality requirements for water meter chambers are included in Valrom Industrie’s Company Technical Standard STF 9/2005. Double-wall construction version: monolithic construction with an outer layer of compact material (mass-colored polyethylene) and an inner expanded polyethylene layer with blowing agents. Component elements – water meter chamber body. Must be purchased separately: – insulated lid, item code 47901000010 – lid insulation gasket, item code 47901000116. Benefits: The monobloc construction, double-wall design, insulated lid, and the closure design and sealing solutions for penetrations (rubber gasket at the lid and for wall penetrations) make water infiltration impossible and protect the internal installation from freezing. The reinforced geometry, with horizontal and vertical ribs, gives the chamber mechanical rigidity without increasing its weight and therefore handling and transport time or costs. Technical approval and certification for use in construction.
