The U.S. Dept. of the Interior, Bureau of Mines, has designed and tested an isokinetic sampling probe for use in studying the hydrodynamic, thermodynamic, chemical, and physical properties of geobrines. This work was conducted as a part of the Bureau's mission to ensure an adequate supply of minerals to meet national economic and strategic needs. The probe consists of a sampling tube for obtaining the fluid sample and two probe consists of a sampling tube for obtaining the fluid sample and two pressure sensing tubes for use in controlling hydrodynamic conditions at pressure sensing tubes for use in controlling hydrodynamic conditions at the entrance to the sampling tube. The three tubes form the basic probe unit and can be mounted on brine processing equipment and pipelines as either a fixed- or an adjustable-position probe.
The isokinetic technique, involving sampling at a rate governed by the pressures in the two sensing tubes, is useful specifically for sampling pressures in the two sensing tubes, is useful specifically for sampling two-phase fluids. Samples so obtained are reproducible and representative of the fluid being sampled. The probe proved capable of examining two-phase flows of widely ranging fluid properties at the Bureau of Mines.
