Klepsan Woltman Water Meters
The size and flow values of the meters in this product are the same as those of the Woltman-type cold water meter in the Klepsan catalog; the technical data shown here are that model's catalog data. Woltman-type meters are flanged, turbine-type mechanical meters used to measure high flow rates in large-diameter lines. This product is the DN65 (2½”) model.
In a Woltman meter, the water turns a turbine aligned with the pipe axis; this design is suited to measuring large flow rates with low pressure loss. The meter is connected to the pipework by the flanges at both ends.
Key Features

Why Klepsan Woltman?
The Klepsan Woltman series measures high flow rates in large-diameter mains with low pressure loss; with the optional pulse output, the meter can be connected to building automation or a remote reading system. As the meters are made in Türkiye, spare parts and service are easy to access.
Installation, Reading and Re-verification
Install the meter between mating flanges of the same nominal size, with gaskets, so that the arrow on its body points in the direction of water flow; the number and size of the bolts must match the values in the table. A strainer upstream of the meter and an isolating valve before and after it make maintenance and replacement easier.
Check your local regulations for the periodic re-verification requirements of cold water meters.
