Woltman parallel type meters are always used when high flow rates with a relative constant flow rate profile are to be measured. Trough its robust contruction they not only are caple of covering a large measuring range, but the measuring accuracy is also long-term stable.
They hydrolic optimize turbine is reabli operated already at small flow rates and ” upward” is has enough power reserve to reably measure flow rate peaks. Especially strong bearings with low friction guarantee along life of the meter.
Reed sensors, optical and indctive – NAMUR sensors can always be retrofitted without the damaging calibration eal. then the meter can be integrated with data communication or automation and control system in a simple and flexible way.
Performance Characteristics in Overview
- Low starting flow, high overload security
- Wide measuring range
- Low head loss
- Hidraulic bearing relieve for long-term measuring stability
- Retrofittable with active 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 to 35°C up to 50°C
- For horizontal, vertical installation positions
- High Pressure
