Entrained Gas Management

Entrained Gas Management EGM now available for all OPTIMASS Coriolis mass flowmeters Entrained Gas Management EGM now available for all OPTIMASS Coriolis mass flowmeters 18 Entrained Gas Management EGM technology is now available for all KROHNE OPTIMASS Coriolis mass flowmeters. With the latest additions OPTIMASS 3400 and OPTIMASS 7400, now the whole OPTIMASS series offers continuous and repeatable mass flow or density measurement with 2-phase flows such as liquids mixed with gas, slurries with gases or highly viscous fluids with gas entrainments. In the past, this presented a huge challenge for mass flowmeters: without gas entrainments, the measuring tubes in the Coriolis mass flowmeter have the desired regular oscillation. Gas entrained in the liquid dampens this regular oscillation, and as the gas content increases, it can come to a complete stop. To overcome this, KROHNE developed powerful control algorithms that allow the meter to maintain oscillation and continue to measure even with complex flow conditions. This is possible even during a complete transition from a pure liquid phase to a gas phase and back, i.e. from 0…100% gas content. Mass flow and density measurements remain stable, continuous and repeatable. Since the introduction of the EGM technology in 2012, OPTIMASS flowmeters with EGM have proven themselves in 2-phase flow and batch/loading/empty-full-empty applications in various industries: • Food & Beverage: raw milk, ice cream, dough, sirup, tomato concentrate, spinach, meat, margarine, mayonnaise, meat, syrup, coffee extract, coolants, sugar concentrates and molasses • Chemical: hydrogen peroxide processing, viscous monomers/ polymers, liquid removal from stirred tanks, highly concentrated assets such as fuming HCl or HNO3, polyurethane foams, push to empty tanks • Oil & Gas: drilling fluids, truck loading/offloading, well heads, tank management Together with the indication or configurable alarm for the user, EGM can also be used to improve processes by identifying transient gas entrainments. To explain the technology and the applications in more detail, “Entrained Gas Management in Coriolis flowmeters” has been released as new course on the free KROHNE Academy online eLearning platform The course consists of one learning module with a corresponding test that allows participants to assess their knowledge, and is currently available in English and German, other languages will follow. About KROHNE KROHNE is a full-service provider for process measuring technology for the measurement of flow, mass flow, level, pressure and temperature as well as analytical tasks. Founded in 1921 and headquartered in Duisburg, Germany, the company employs over 3,600 people all over the world and is present on all continents. KROHNE stands for innovation and maximum product quality and is one of the market leaders in industrial process measuring technology.

SICK Automation helps Egoli Gas reduce unaccounted gas The FLOWSIC600-XT delivers maximum ultrasonic gas flow measuring precision for any application requirement as a standalone or system solution. Three intelligent gas flow meters from SICK Automation commissioned at the end of 2016 helped natural gas supplier Egoli Gas reduce its unaccounted gas (UAG) by a significant amount. That success that has now been replicated on a much larger scale across the gas supplier’s distribution infrastructure, with 29 additional flow meters being delivered at the end of 2017. The meters – the FLOWSIC500, FLOWSIC600 and FLOWSIC600-XT – supply the level of accuracy required for quantifying low flow rates that was not possible with typical mechanical gas meters, providing a greater operational and process transparency that allows the gas supplier to reduce issues of losses, incorrect billing and theft. “These smart solutions have greatly improved the transparency of our processes, enabling us to gauge and analyse consumption and gas flow in real time for different flow ranges,” explains Emmanuel Matodzi, Technical Manager, Egoli Gas. “Apart from a technologically superior and high-reliability product, SICK provided a level of assistance and support across the project that exceeded our expectations.” Egoli Gas provides gas to 7 500 domestic, commercial and industrial users in the area. The company operates a 1 800-km gas distribution network that dates back to 1892. About SICK Automation SICK is one of the world’s leading producers of sensors and sensor solutions for industrial applications. Founded in 1946 by Dr.-Ing. e. h. Erwin Sick, the company with headquarters in Waldkirch im Breisgau near Freiburg ranks among the technological market leaders. With more than 50 subsidiaries and equity investments as well as numerous agencies, SICK maintains a presence around the globe. In the fiscal year 2015, SICK had more than 7400 employees worldwide and achieved Group sales of just under EUR 1.3 billion.
