FLOW MEASUREMENT

First technology qualification certificate for fiscal metering

Emerson ’s Daniel 3415 and 3416 Dual-Configuration Gas Ultrasonic Meters have received the industry’s first Technology Qualification (TQ) fromDNV GL for fiscal gas meters, a risk-based assessment that evaluates meter performance in real-life operational environments to ensure the technology meets the highest fiscal measurement standards.TheTQ verifies the meter’s ability to meet the industry’s fiscal and contractual requirements when operating under field conditions where dust, liquids, build-up, drift and pulsations are common. It also authenticates the ability of the meter’s advanced diagnostics to detect and compensate for process disturbances and provide early warning of fouling to ensure greater meter in- tegrity and measurement accuracy. Furthermore, theTQ confirms the robustness and reliability of the new Daniel Ultrasonic Meters in minimising financial risk and provides evidence to support ex- tending calibration intervals to reduce operating costs. “Current international gas measurement standards for fiscal flow meters

focus only on the design and installation of the meters and don’t cover meter performance under field conditions,” said DNV GL’s oil and gas senior vice president, Liv Hovem. The Daniel Dual-Configuration 3415 and 3416 Gas Ultrasonic Me- ters, which are already certified to the stringent OIML R137 1&2 Accuracy Class 0.5, are the only ultrasonic meters on the market

today that have undergone DNV GL’s rigorous field testing and demonstrated field robust- ness. The DNV GL assessment process is built upon scientific research and is recognised by regulators, insurers, and major clients throughout the world. Enquiries: Rob Smith.
