Daniel Gas Ultrasonic The Benefits Of Combination Of Reflective And Direct Path
Author(s): Thomas Sautier
Abstract/Introduction:
Customers worldwide have adopted Ultrasonic flow measurement for Custody Transfer Gas Measurement Multi Path technology with generally either 100% Chordal or 100% Reflective paths configuration provides the best achievable calibrated accuracy... Both have Pros and Cons. Even if fiscal metering & dirty gas doesnt go together well, the reality in the field is different. During operation, uncertainties due to process change, possible contamination, liquid & wet gas can be an issue. Emerson Daniel has 25 years of experience with both Chordal & Reflective technology and believe combination of best of both worlds can help - To increase the confidence level of the US meter - To get early warnings in case of process related issues of these operational uncertainties.

Two Phase- Flow Metering Of Heavy Oil With Coriolis Mass Flow Metering: Formal Trials At NEL
Author(s): Manus Henry Michael Tombs Feibiao Zhou
Abstract/Introduction:
Department of Engineering Science Coriolis Mass Flow Metering Most flow meters measure volumetric flow (for example 2000 barrels /day) Coriolis meters measure mass flow (for example 20 tonnes/day) Mass is more useful than volume in many applications (for example petrochemical) Coriolis meters are accurate (0.1%) compared with many other types of flow meter. Coriolis meters have two parts - The flow tube, a mechanical device, through which the fluid flows - The transmitter, an electronic device, which makes the flowtube vibrate, and which does the flow calculation

Machine Learning For Condition- Based Flowmeter Management
Author(s): Kojo Sarfo Gyamfi James Brusey Andrew Hunt Elena Gaura
Abstract/Introduction:
Flowmeters Subject to deviation: Waxing, Noise, Meter misalignment, etc. Problem of incorrect measurement - high flowrate attracts high tax liabilities. Recalibration: time of operation. Two main problems: 1) Malfunctioning meter before schedule. 2) Perfectly operating meter at schedule. e.g. u30,000 for USM recalibration 5 Condition- based flowmeter management (CBM

Just What Are We Calibrating?
Author(s): Ron Sangster Bob Maurer,
Abstract/Introduction:
Remote operation and reporting by sensors with built in intelligence is a massive growth industry. To meet this demand many instrument manufacturers now supply intelligent systems which can be interrogated /controlled by hand held or remotely operated equipment. These interrogate the signal conditioning modules mounted on the primary measuring elements. Gathered information from the circuitry in the sensor can be compared and verified against the original calibration data produced at the time of manufacture. Does this simple verification imply that since installation /calibration, that some deterioration of the actual measuring elements has not taken place, If deterioration has taken place , the magnitude of the calibration shift and by definition the integrity of the instruments readings will not be made manifest That this deterioration will not necessarily affect the integrity of the last or original calibration or that it does not affect the calibration or can be monitored and corrected for. Environmental conditions at the sensor location, can cause the loss of integrity and have serious implications in that any damage, obstruction, corrosion, erosion, buildup of lime scale, fatigue etc. will affect the results from the sensor
