Entrained Gas Handling in Micro Motion® Coriolis Flowmeters - Tim Patten - This white paper discusses the measurement problems caused by process fluids that contain bubbles of air or other gas, and describes how Micro Motion® sensor and transmitter technology can be used to overcome those problems. It also presents suggestions for minimising measurement problems by improving application design.

Accurate Flow Measurement Improves Profit - Two-wire Coriolis Flowmeter for Loop Powered Applications - Rough Economic Seas - The current economic climate means that many managers are taking a keen interest in the selection of their flow-measuring devices. Today’s decision makers understand the benefits of different flow technologies and accept that when migrating to higher performing technologies, there may be cost implications resulting from, for example, increased wiring and associated installation costs. In a new installation, these extra costs can usually be minimized through good engineering practices.

Coriolis Mass Flowmeters Take Center Stage for Bulk Measurement in Oil & Gas Industry - Andre Verdone - Accurate measurement of liquids is important for all oil and gas production or consumption sites. This is especially true for bulk-transfer devices where large volumes of products are being moved and must be monitored, including crude oil depots, gasoline and jet fuel tank farms, refineries, and even cruise line terminals. In the past, mass transfer was measured in batches with weigh scales or load cells. However, installation, calibration and maintenance of a scale or load cell are costly, difficult to do, time consuming, and don’t work for continuous processes. For these processes, such methods as orifice plates and magnetic flow tubes can measure volumetric flow, but additional instruments are needed to measure temperature and pressure to compensate for fluid density changes. Introducing additional instruments also introduces errors, which can result in an overall measurement error rate as high as 3 percent. Now several measurement standards are moving toward use of Coriolis mass flowmeters, which can measure mass flow directly at the same time as they measure temperature and density. What’s more, transfer measurement by mass is the most accurate method, since mass is independent of, and unaffected by, changing process fluid characteristics, including pressure, temperature, viscosity, conductivity, and gravity - from Flow Control.
