Restriction orifices are used to generate a defined pressure loss in process piping or blow out lines. In special cases they may be designed to limit the flow to a specific value. Restriction orifices are applicable for all single phase fluids.

Orifice flanges are used in conjunction with orifice plates for flow measurement of aggressive and non-aggressive gases, steam and liquids.

Orifice plates with single bore pressure taps are used as flow elements for flow measurement of aggressive and non-aggressive gases, steam and liquids.

Ring chamber orifice plates with pressure taps are used as flow elements for flow measurement of aggressive and non-aggressive gases, steam and liquids.

Generally, weld-in orifice plates are utilized for high pressure and high temperature applications, e.g. in power plants. They can be manufactured with (EBLA 800) our without (EBLB 800) a ring chamber tapping. If needed, we can weld inlet and outlet pipe sections to the orifice plate. These pipe sections usually are provided by the customer. The welding seams are mechanically processed in order to meet the surface roughness requirements of the respective calculation standard.

Meter runs combine inlet and outlet piping with a flow element which is used for flow measurement of single phase aggressive and non-aggressive gases, steam or liquids, especially for small pipe diameters up to DN 50 (2"). Due to the integrated in- and outlet pipes flow disturbances can be reduced. For steam and gas measurements we can include additional taps in the inlet and outlet for pressure and temperature compensation.

ISA 1932 nozzles are used as flow elements for flow measurement of aggressive and non-aggressive gases, steam and liquids.

Long radius nozzles are used as flow elements for flow measurement of aggressive and non-aggressive gases, steam and liquids.

Venturinozzles are used as flow elements for flow measurement of aggressive and non-aggressive gases, steam and liquids.

Weld-in ISA 1932 nozzles are used as flow elements for flow measurement of aggressive and non-aggressive gases, steam and liquids.
