Zenner WI-N Woltman Tangential Paddle Wheel 50mm Table D Flanged Water Meter

50mm Woltman water meter for loaded water, featuring Table D flanges, a removable measuring insert and optional 10L pulse output.

The Zenner WI-N 50mm Woltman Water Meter is designed for measuring raw, loaded or contaminated water in agricultural, irrigation, wastewater and industrial applications.

Its tangential paddle wheel measuring insert is positioned in the upper section of the meter body, where fewer suspended particles generally travel. This allows the WI-N to reliably measure water containing a suspended-material load of up to 30%. An upstream filter is recommended for particularly heavily loaded water.

The removable, factory-tested measuring insert makes inspection and maintenance easier, while the fully encapsulated roller register protects the display from water and contaminants. A lockable metal cover provides additional protection in demanding outdoor and industrial environments.

Choose the standard model for manual readings or the pulse-output version for connection to compatible dosing pumps, irrigation controllers, displays, data loggers and monitoring systems. The pulse version provides one pulse per 10 litres.
