Zenner Water Meter Woltman WI-N

Shipping calculated at checkout.


The Zenner WI-N Water Meter is used to measure the volume of flow in many water applications, including heavily contaminated water. For example in irrigation bore water, sewage treatment plants or wastewater systems.

The measuring element, either a Tangential Paddle-Wheel (for 80…200 mm NB sizes) or the Turbine design (for 50 mm, and 250…500 mm NB sizes), is positioned high up in the Meter body where this is often less debris or particulate flowing in the water. This feature can be quite forgiving on the mechanism when dealing with dirty or raw ground water.  And they are simple to maintain thanks to the removable measuring insert, allowing for it to be cleaned out if need be.

The completely encapsulated mechanical register is a non-resettable totaliser. All Meters are fitted with a 2-wire Pulse Output for connecting up to one of our popular Contrec Rate & Total Display (see our Contrec 100D-Series), Data Logger or your onsite monitoring system.
