Woltman Water Meter With Paralele Turbine Shaf
Woltman parallel type meters are always used when high flow rates with a relative constant flow rate profile are to be measured. Trought its robust construction they not only are capable of covering a large measuring range, but the measuring accuracy is also long-term stable.
They hydrodynamic optimize turbine is reliabli operated already at small flow rates “upward” is has enough power to reliably measure flow rate peaks. Especially strong bearing with low friction gurntee a long life of the meter.
Reed sensors, optical and invoice – NAMUR sensors can always be retrofitted without the damaging calibration eal. Then the meter can be integrated with data communication or automation or automatiin and control system in a simple and flexible way.
Performance Cracteristics in Overview :
- Low starting flow, high overload security
- Wide measuring range
- Removable measuring insert
- Low head loss
- Hidraulic bearing reliece for long-term measuring stability
- Retrofittable with acctive and passive pulsers
- Metal Protective cover serially, plastics optional
- Eacuated counter protected from condensation
- Dry dial counter with large number rollers simplities the readability
- For cold water up 30°C, with security up to 50°C
- For horizontal, vertical installation position
- High Pressure
