Product Description

Product Description
Multi jet ,dry dial, direct reading. 
Producted in the versions for cold water 30ºC.
Long durability and elevaated precisions guaranteed.

Characteristics:
All the Materials in contact with water, consciously selected by the known resistance to corrosion;
Cold water meter under current standard for lower than 30ºC(T30), but  the type meter can be used safely in water temperature up to 50ºC(T50);
The ROTARYindicator register for the most comfortable reading position of 5 Rollers (Dn40 with 6 Rollers) and 4 Pointers;
The Impeller is the only moving parts in contact with water permitting the most reliable;
The extra inlet filter at the inlet of the meter body permits cleaning it without breaking the metrological seal;
The conception of the Magnetic Protection to against the external influences;

Maximum permissible error:
From the minimum flow-rate (q1)inclusive to the lower zone of the transitionalflow-rate (q2) exclusive: ± 5%.
From the transitional flow-rate (q2) inclusive to the higher zone of the maximum flow-rate (q4) exclusive: ± 2%
(hot water meter± 3%. )
