Due to the simple design in accordance with ISO 5167-2 and their ease of installation, even in existing piping systems, orifice plates are ideal for flow measurement in numerous applications in the chemical and petrochemical industries and also in water treatment. A number of variants can be used for the exact flow measurement of gases, liquids and vapours. Depending on the operating conditions, RF, FF oder RTJ sealing faces are available. To ensure optimal installation, the bore and geometry of the orifice plates are adapted to the respective application in accordance with customer specifications. For high accuracies of ≤ ±1.0 % of the actual flow volume, orifice plates with longer meter runs are used.
