DESCRIPTION: Differential pressure flow measurement is widely used to its excellent relationship between installation cost, maintenance and performance. The new designs of differential pressure transmitters, increasingly precise and capable of integrating a greater number of process variables, ratify the versatility, reliability and validity of this primary elements.
Eccentric and segmental orifice plates are used for fluids that are dirty and contain sediments.
Applications
- Flow measurement in highly viscous fluids with low Reynolds number.
- For all types of industrial plants such as:
- Energy generation.
- Chemical and petrochemical industries.
- Renewable energy.
- Food industry.
- Water treatment.
Design
- Calculation standards:
ISO / TR 15377
ASME FLUID METER - Materials: Carbon steels, low alloys and steel alloys (orifice flanges). Stainless steel and high alloys (orifice plates).
- Size of Manufacture:
Eccentric: 4” – 40”
Segmental: ≥4” - Flage finishes: RF, FF, RTJ
