ADJUSTABLE SEGMENTAL ORIFICE PLATE

use: transfer gas station with continuous operation.
Segmental orifice plate enables to change scope of measured flows by change of flow section during operation (change of depth of segment insertion). This way change between pressure difference and flow is modified continuously.

ORIFICE PLATE WITH CONICAL INLET
(former conical orifice plate)

use: viscous fluids (oils), operation modes under low Reynolds numbers. It is analogic to classical orifice plate, entrance is conically bevelled.

QUARTER CIRCLE ORIFICE PLATE 
(former quarter Koenneck nozzle)

Use: viscous fluids (oils), operation modes under low Reynolds numbers. It is analogic to classical orifice plate, inlet has quarter-circle radius
