Benefits of TRACERCO™ Smart Density Gauge

• No moving or wetted parts, leading to reduced maintenance and high reliability
• Provides real-time in line or in vessel measurements
• External automatic compensation for changes in vessel operating pressure

The TRACERCO™ Smart Density gauge is a custom designed density measurement system that can be used in a wide range of applications on a refinery or chemical processing plant including:

• Density measurement of single, two or three phase process mixtures
• Gas or water slug presence, velocity, volume and frequency
• Oil in water or water in oil breakthrough at low levels in two phase separators
• Liquid carry over or vapor carry under within separation vessels
• Solids build-up on vessel or pipe walls
• Measurement of slurry concentrations in vessels or transfer pipelines

The TRACERCO™ Smart Density gauge is a non-invasive system designed to ensure reliable density measurements. The gauge consists of a very small radioactive source housed within a shielded container and a sensitive detector. The detector is housed in a flameproof enclosure and is suitable for use in hazardous areas up to and including Class 1 Div 1. The detector and shield are mounted externally to the pipe with no moving parts eliminating mechanical failure or fouling. Radiation is attenuated by material placed in its’ path. Attenuation depends on the thickness of the material and its density. In a typical application within a processing plant the radiation beam will be attenuated by the pipe or vessel walls and the process medium. As attenuation by the walls is constant, any variation in intensity at the detector will be caused by variation in the process medium. The system is calibrated using known densities of materials passing between the source and detector. The radiation count rate is stored within the instrument microprocessor for a given density. This is then used to accurately calculate density of materials within the process at any given time.
