Extended range custody-transfer
Dual-Beta Orifice Plates — Wide-Range DP Flow Meter
Two independent β sections in one assembly, each designed to ISO 5167-2:2022 — enabling wide-range measurement with standardized orifice elements.
Dual-Beta Orifice Plates
Engineered for the service
Per ISO 5167-2:2022, the Dual-Beta orifice plate integrates two standard orifice sections with different β ratios in a single carrier. Each section is independently calculated to ISO 5167-2:2022, enabling wide turndown while keeping each measurement path within the applicable orifice-plate framework.
Key design features
Each section independently conforms to ISO 5167-2:2022
50:1 turndown with standards compliance
Eligible for custody transfer
No non-standard elements or special calibration required
