Zenner WPH-N Woltman Water Meter with Parallel Turbine Shaft

The Zenner WPH-N is a high-performance Woltman water meter engineered for the precise measurement of large volumes of cold potable water in commercial, industrial, and municipal networks. With a parallel turbine shaft design, the WPH-N delivers excellent measuring stability and minimal pressure loss, even at fluctuating flow rates.

Its rugged construction, removable measuring insert, and vacuum-sealed register make it ideal for demanding installations where long service life, easy maintenance, and reliable accuracy are essential. The flanged design ensures secure installation across DN50 to DN100 pipelines, with sizes up to DN500 available on request.
