Zenner WI-N Woltman Turbine Impeller 500mm Table E Flanged Water Meter

500mm Woltman turbine impeller water meter with Table E flanged connections, robust cast iron housing, encapsulated dry-dial register and 16 bar maximum operating pressure.

The Zenner WI-N 500mm 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 Woltman measuring insert is positioned in the upper section of the pipe, where there are generally fewer suspended particles in the flowing water. This design allows the meter to operate reliably with polluted water and water containing suspended 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 register helps protect the counter from dirt and harsh operating conditions. The meter is suitable for horizontal and vertical installation and is designed for cold water applications up to 50°C.

The 500mm WI-N is designed for high-volume water measurement in large agricultural irrigation, raw-water, wastewater and industrial systems. The DN500 configuration has a nominal flow rate of 2,500,000L/h and a maximum flow rate of 3,125,000L/h. The minimum flow rate is approximately 31,250L/h. The meter has a maximum operating pressure of 16 bar (1,600kPa).

A reed pulser can be retrofitted for connection to compatible monitoring equipment, data loggers, remote displays, irrigation controllers and control systems. For larger WI-N meters in the DN400–DN500 range, the standard pulse value is 10,000L per pulse, with alternative pulse values available on request.
