Three versions of the standard orifice plate are distinguished:
One-piece mounting ring with non-replaceable measuring insert. The easy-to-clean individual bores are particularly advantageous for media that resinify or build up, or for systems that do not remain in operation continuously.
Two-piece frame ring with ring chamber removal and exchangeable measuring insert. The ring chamber removal creates a good average value of the plus and minus pressure. This produces a smoother measuring signal.
Standard orifice plates – whether with annular chamber (EBLA 800) or without (EBLB 800) – can also be offered as weld-in differential pressure devices. These are used in the high-pressure and high-temperature range.
We are happy to expand the weld-in orifice plate with a welded-on inlet and outlet pipe to meet the requirements of the calculation standard.
Typical versions of the pressure taps are:
Depending on the application, the measurement uncertainty is approx. 0.5% – 1.2% of the flow coefficient.
Standard orifices – be it with ring chamber (EBLA 800) or without (EBLB 800) – can also be offered as weld-in differential pressure elements. These are used in the high-pressure and high-temperature range.
We would be happy to expand the weld-in panel with a welded-on inlet and outlet pipe in order to meet the requirements of the calculation standard.
Standard orifices can be equipped with shut-off valves and/or valve blocks. Condensate vessels are recommended for steam applications.
