Sonar-array technology aids flow measurements

CiDRA first developed its patented sonar-array technology for undersea/down hole oil, water, and gas flow measurements, and has now applied it to more traditional flow measurements. SONARtrac flow monitoring system is non-intrusive because it clamps onto the pipe, and requires no special upstream or downstream installation requirements.

CiDRA first developed its patented sonar-array technology for undersea/down hole oil, water, and gas flow measurements, and has now applied it to more traditional flow measurements. SONARtrac flow monitoring system is non-intrusive because it clamps onto the pipe, and requires no special upstream or downstream installation requirements.

Because SONARtrac flowmeters are robust full-bore and clamp-on, they also require no process downtime to install. Installation occurs as the process is running. This passive, sonar-based technology enables accurate measurement of the thickest slurries, and even allows measurement through lined pipes.

In one particular application, a continuous digester monitored flow of high consistency pulp in a digester blow line. CiDRA reports that the existing flowmeter required frequent replacement. Downtime and lost production to replace existing in-line meter totaled four hours and more than $100,000. Sonartrac was able to reduce the unit’s lifecycle costs; increase process uptime and equipment utilization; lower operating costs, and enhance its process safety/management programs. www.cidra.com

  • Versatile process monitoring system

  • Provides multi-variable measurements, such as volumetric flow and entrained air

  • Works in many fluid regimes, such as liquids, gases, slurries, and multiphase fluids
