Bulk water meter WPH-N-CC 90°

The WPH-N-CC water meter by ZENNER is always used when high flow rates with a relative constant flow rate profile are to be measured.

Through its robust 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” 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 can always be retrofitted without damaging the calibration seal. Then the meter can be integrated with data communication or automation and control systems in a simple and flexible way.
