Mine of the Month - LKAB Kiruna - Taking mining to a new level (page 19)

Mining Magazine visited the Kiruna mine in Sweden, the world’s largest underground iron-ore mine, to review the operation and owner LKAB’s ambitious expansion plans

US company CiDRA Corp is supplying SONARtrac flow-technology systems for all magnetite slurry measurements in Kiruna’s new KA3 and KK4 plants.

Measuring the Flow of Liquids with NonCondensable Gas

Getting the air out is a cardinal rule of liquid flow measurement, but sometimes the gas is a necessary and desireable component of the mixture. Then what?

Mined products made responsibly - Saving Water (page 38)

In all process plants it is, obviously, important that process flows and waters do not escape. CiDRA's SONARtrac process monitoring systems offer full-bore, non-invasive flow and entrained air/gas measurement technology.

Hype vs. Reality - Not So New Flowmeter Technology

Where is the line between hype and reality? How should we determine what is new technology and what is simply a different incarnation of previous technology? These questions may seem philosophical, but their answers may hold the key to specifying, purchasing, and installing superior flow measurement systems.

Measurement at speed of sound - New method using coriolis can gain aerated liquid accuracy

Although the mass flow rate and process fluid density measurements determined by Coriolis meters derive from independent physical principles, the accuracy of both significantly degrade with the introduction of small amounts of entrained gases. That is why there is a new method to improve the accuracy of vibrating tube-based density measurements of aerated liquids.

Accurate Liquid Phase Density on Aerated Liquids - White Paper

Introduction: Density is one of the most widely used composition-based measurements in industrial process control. However, it is well recognized that the presence of small, but unknown levels of entrained gases can mask the density of the non-aerated component of a process mixture, resulting in an inaccurate determination of process fluid density. Recently, SONAR-based, clamp-on gas volume fraction meters have been introduced which provide an accurate, real time, measurement of entrained gases.

July 2003: Trends Among the Top 10 Flowmeter Technologies - by Jesse Yoder, President of Flow Research

Beyond the Top 10:

"In addition to these 10 technologies, there are several others including target meters. More exciting is the development of what appear to be genuinely new flow technologies. One is the Sonartrac flowmeter from CiDRA Corp., which uses sonar techniques to measure volumetric flow. The meter senses pressures on a pipe caused by naturally occurring vortex-like disturbances in turbulent flows. It is intended for industrial applications."
