1.Scope 1.1.Acoustic waves from impact of proppant on pipe walls is used to measure proppant density of the slurry. 1.2.Sensors are mounted on a pipe elbow to measure impact of the proppant with the inside of the pipe elbow wall. 1.3.Liquid Component can be any liquids from water to Gels. 1.4.Proppant is sand or other particles of known size. 1.5.Slurry flow is turbulent as it passes under the sensor to achieve uniform density. 1.6.This practice can be used to replace radioactive methods which are more expensive and have significant safety risks.
Nuclear density meters are currently the industry standard, but have become expensive to maintain. A non-radioactive method would be a substantial benefit to the hydraulic fracturing industry.
The title and scope are in draft form and are under development within this ASTM Committee.
