DS TRP MID WATER METER

DS TRP MID multi-jet water meters feature a sealed register and permanently protected dial design.
The plate showing the measurement and the MID inscriptions does not come into contact with the flowing water. As a result it remains perfectly clear ensuring reading with scaling and ferrous water and suspended particles contained in water. Readability is also ensured by the mineral tempered glass lens which has a flat and smooth surface and, unlike plastic lenses, is scratch resistant and does not turn opaque. DS TRP MID meters are unaffected by external magnetic interference and are tamper proof. Performance is unaffected by the installation conditions and the water characteristics. DS TRP MID water meters may be equipped with a new generation bidirectional static pulser. The pulser may also be retrofitted in pre-equipped water meters maintaining the meter characteristics, the design and the mineral glass lens.

NEW VERSION

DS TRP MID meters are now available in a new version ready for retrofitting an inductive pulser. They are the only sealed register meters available in this design and that retain the glass lens. This has been made possible  
by the introduction of a new glass (GORILLA GLASS), widely used in electronic devices, that enables the use  
of a fully non-magnetic sensor (patent pending).

DS TRP MID water meters are certified in accordance with the Directive 2004/22/EC (Annex MI-001) and have undergone conformity assessment procedure B+D. The maximum measuring range Q3/Q1 (R) certified is 200. As a result, water meters with a lower ratio (R160, 125, 100, etc.) may be manufactured. DS TRP MID water meters are also certified for use with potable water in accordance with the Italian ministerial decree 6 April 2004 no. 174 and international regulations.
