Zenner WI-N Woltman Turbine Impeller 300mm Table E Flanged Water Meter

300mm Woltman turbine impeller water meter with Table E flanged connections, robust cast iron housing, dry-dial register and 16 bar maximum operating pressure.

The Zenner WI-N 300mm Woltman Water Meter is designed for reliable measurement in demanding applications where water may contain significant levels of suspended particles or contamination. It is particularly suited to agricultural irrigation, bore water, sewage treatment plants, wastewater systems and raw-water applications.

Its turbine impeller measuring mechanism is positioned in the upper section of the meter body, where there are generally fewer suspended particles in the flowing water. This design helps the meter operate reliably with polluted or raw water, with the WI-N capable of handling water containing up to approximately 30% impurities. Where water is heavily contaminated, an external filter can be installed upstream of the meter.

The robust cast iron meter body incorporates a removable measuring insert for straightforward inspection and maintenance. Its completely encapsulated mechanical dry-dial register helps protect the counter from dirt and harsh operating conditions. The meter is suitable for horizontal or vertical installation and is designed for cold water applications up to 50°C.

The 300mm WI-N uses a turbine measuring design and Table E flanged connection. It is intended for high-volume water measurement in large irrigation, raw-water, wastewater and industrial systems. The WI-N series has a maximum operating pressure of 16 bar (1,600kPa), with the 300mm model falling within the DN150–DN300 range that uses a standard 1,000L pulse value when fitted with a reed pulser.

A reed pulser can be retrofitted without damaging the calibration seal, allowing the meter to connect to compatible monitoring equipment, data loggers, remote displays, irrigation controllers and control systems. The standard pulse value for WI-N meters from DN150 to DN300 is 1,000L per pulse, with other pulse values available on request.
