Woltman parallel type meters are always used when high flow rates with a relative constant low rate profile are to be measured. Through its robut construction they not only are capable of covering a large measuring range, but the measuring accuracy is also long-term stable.
The hydrodynamic optimized turbine is reliably operated already at small flow rates and “upwards” is has enough power reserves to reliably measure flow rates peaks. Especially strong bearings with low fiction guarantee a long life of the meter.
Reed sensors, optical and inductive-NAMUR sensors can always be retrofitted without damaging the calibration eal. Then the meter can be integrated with data communication or automation or automatin and control systems in a systems in a simple and flexible way.
