Wph-N (DN50-500)

Woltman Parallel type meters are always used when high f ow rates with
A relative constant f ow rate prof le are to be measured. Through its robust
Construction they not only are capable of covering a large measuring ran-
Ge, but the measuring accuracy is also long-term stable.

The hydrodynamic optimized turbine is reliably operated already at small
Flow rates and "upwards" it has enough power reserves to reliably measure
Flow rate peaks. Especially strong bearings with low friction guarantee a
Long life of the meter.

Reed sensors, optical and inductive-NAMUR sensors can always be re-
Trof tted without damaging the calibration seal. Then the meter can be in-
Tegrated with data communication or automation and control systems in a
Simple and f exible way.
