Orifice plates can be designed and calculated in accordance with any required standard. Den Holder standard plates are in stainless steel 316L, with RF gasket surface and with material certificates 3.1B. Of course, all other materials, including material certificates, are possible, as well as other designs and standards, such as DIN or JIS, RTJ oval or octagonal.

Den Holder stamps the measured orifice diameter in the tagplate in order to use the exact dimensions in the flow computer. Strength calculations can be provided to check the thickness against pressure loss over the plate.

Since base materials are in stock for the most common sizes, prices can be kept low and delivery times are short. Rush deliveries can even be made the same day.
