Restriction orifice plates


Weld-in standard orifice plates are used as differential pressure transmitters for measuring the flow of aggressive and non-aggressive gases, steams, and fluids. In contrast to the detachable orifice plates, they include a carrier ring and tapping fittings and can be easily installed and connected between normal pipe flanges.


One-piece carrier ring with non-exchangeable measuring insert. The easily cleaned single bores are particularly advantageous for media that resinify or form deposits or in plants that do not remain constantly in operation. Standard orifice plates can be equipped with shutoff valves and/or valve blocks. Condensate traps are recommended for steam applications. Two-piece carrier ring with annular chamber tapping and exchangeable measuring insert. A good average value is formed for the positive and negative pressure thanks to the annular chamber tapping. A steadier measured signal is generated as a result.
