Venturi Tube

A Complete line of differential pressure ASME Herschel type venturies are manufactured by Scientific Devices This type of flow elements have been universally accepted as the most efficient primary devices available. No other type of Venturi or flow tube design has been more thoroughly researched, tested and proven than the ASME type.

 Flow Nozzles

Scientific Devices Flow Nozzles are calculated, design and manufactured to ASME recommended to provide high accuracy flow measurement. The flow nozzle offers some distinct advantages over the thin plate orifice in that it produces loss of differential pressure for a given beta ratio resulting in overall lowerpermanent 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 or protusions to wear.
