Maddalena CD SD Plus single jet cold water meter





Maddalena CD SD Plus cold water meter  is a dry single jet water meter suitable for remote water consumption metering and monitoring.

CD SD PLUS utilizes a magnetically driven dry dial design and is suitable for use with either cold (T50) or hot (T30/T90) water.

The impeller is the only part in contact with the water, thus ensuring readability with scaling water or with water containing small debris or sand particles.
CD SD PLUS water meters comply with Directive 2014/32/EU (Annex MI-001) and have undergone conformity assessment procedure B+D.

The maximum measuring range Q3/Q1 (R) certified is 100 for horizontal position and 50 for vertical position.

The water meter is a good budgetary option for a mechanical water meter with ability to easily retrofit with pulse output and a data logger.

The meter is manufactured by Maddalena SPA (Italy). However it is used also by a couple of other vendors including Siemens (WFK meters are kind of exactly the same) as CD SD PLUS of Maddalena.

CD SD PLUS water meters are certified for use with potable water in accordance to MID and has WRAS approval.
