Habu Process offers a range of Orifice Plate.
In flow control applications, orifice plates are used as restriction devices to regulate fluid flow or reduce the flowing pressure downstream of the orifice plate. The use of a fixed restriction orifice can be beneficial and economic by reducing the demands on other flow system components.
Orifice plates are one of the most popular devices for the measurement and control of fluid flow. The shape and manufacturing tolerances of plates used in measurement applications are defined in the international standardization publications of ISO, AGA, ASME and others. From the formulas and data within these publications, the relationships and values of flow, differential pressure, and plate bore are determined
Easy Installation and handling
Differential pressure flow meters are used in many technical applications. As primary flow elements, orifice plates represent the most common solution. Orifice plates are notable for their easy installation and management.
The differential pressure generated by the primary flow element is normally transformed into an electrical signal proportional to the flow rate by a differential pressure transmitter.
Optimised to customer requirements
Our primary flow elements are optimised with respect to customers' requirements and therefore match the respective final applications perfectly. The design of the bore is matched ideally to the particular characteristics of the plant.
Our products are available with RF, FF or RTJ sealing faces. For special applications, designs in accordance with customer standards can also be provided.
Description of Orifice Plate
Orifice plates are the simplest type of primary flow elements. Their bore diameter is calculated to generate the specified differential pressure at full scale flow rate. Suitable orifice plates are available for a wide range of different media.
Description of Orifice Flange
For the mounting of orifice plates or flow nozzles, instead of pipe flanges, special orifice flanges are used. Orifice flanges feature pairs of pressure tappings which are machined directly into the orifice flange. This has the advantage of dispensing with any orifice carriers or pressure tappings in the pipe wall.
The assembly of the orifice plate is completed with jacking screws to ensure an easy removal.
Description of the Annular chamber
Annular chambers are used to achieve stable measurements under difficult process conditions. They are mounted between already installed process flanges. The different pressure in the pipe is compensated for by using a gap located between the interior of the pipe and the annular chamber.
