Energy Flow Systems flow nozzles are calculated, designed and manufactured to ASME recommendations to provide high accuracy flow measurement.
The flow nozzles offers some distinct advantages over the thin plate orifice in that it provides less differential pressure for the given beta ratio resulting in overall lower permanent pressure loss. Conversely, the flow nozzle will allow maximum flows nearly twice as great as a thin plate orifice with the same differential pressure.
Accuracy is also sustained indefinitely since there are no sharp edges.
