Klepsan Woltman Water Meters
Klepsan Woltman water meters are flanged, turbine-type mechanical meters built to measure high water flow rates in large-diameter mains. The hot water model measures hot water up to 90 °C and is offered in seven sizes from DN50 to DN200. This product is the DN150 (6”) 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.

- Monitoring hot water consumption at block and building inlets
- Industrial hot water lines
Why the Klepsan Woltman Hot Water Meter?
In large-diameter hot water lines, a Woltman meter measures high flow rates with low pressure loss. Suitable for hot water up to 90 °C and available with an optional pulse output, it is well suited to main-line metering in central hot water systems; since it is manufactured in Türkiye, spare parts and service are easy to obtain.
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 hot water meters.
In Türkiye, Novus Energy provides remote meter reading and consumption-based cost allocation services for buildings with central heating systems.
