Straight-Tube Friction Flow Testing
The Grace Instrument M9250 Friction Flow Loop is designed to use a straight tube flow structure to evaluate the performance of a friction reducer for oilfield use. This automated system circulates test fluid through multiple tube sections of varying diameters in order to test flow rate vs. differential pressure under various diameters.

Automatic Computer-Controlled System
This system comprises a standard 30 gallon plastic tank with paddle stirrer to fully mix additives into the base fluid. The test fluid will then be pumped into the friction loop, with the flow rate set by using the mass flow meter. Differential pressure transducers are mounted on two sides of the test sections, and the differential pressure is logged into the analysis software directly.

Analytical Software Included
The friction loop system includes interactive graphics-based software which allows the user to automatically control and operate the loop system, while recording the data for pressure, flow rate, and temperature. A data graph can be generated in order to analyze the effectiveness and performance of friction reducer.
