Friction Flow

M9350 Mini Friction Flow Loop

Innovative, Compact Straight-Tube Flow Design
The Grace Instrument M9350 Mini Friction Flow Loop system's innovative straight-tube flow design evaluates the performance of friction reducers used in oilfields. This conveniently computer-controlled system circulates test fluid through a single tube section to test flow rate vs. differential pressure. The M9350 is very compact in size compared to other friction flow loop testers, maximizing laboratory space. It can even be placed on a benchtop and easily moved from lab to lab.

Robust Mixer, Precise, Software-Controlled Flow Rate, and Real-Time Testing Results
The M9350 features a low shear, progressive cavity pump for fluid circulation. It also includes a durable 5-gallon polymer tank with paddle stirrer to fully mix friction reducing agents into the base fluid. The test fluid is circulated through the straight tube. The desired flow rate can easily be set using the software and displays in the software in real-time. Flow rate can also be displayed in real-time on the mass flow meter. A differential pressure transducer and thermocouple measure the pressure drop and temperature across the test section. Measuring results are directly logged into the friction flow loop analysis software, conveniently preinstalled on an included Windows PC (sold separately) connected to the unit.

Advanced, Easy-to-Use Software
The M9350's interactive software is easy-to-use and intuitive. This advanced software allows users to automatically control and operate the loop system at target flow rates and record data for pressure, flow rate, and temperature at the same time. Furthermore, detailed data, including graphs and a data table, can be autogenerated and opened in spreadsheet format to further analyze the effectiveness and performance of tested friction reducers.

Hydraulic Fracking and Oilfield Applications
The M9350 is a powerful testing tool, accurately measuring the performance of friction reducers which can be applied to hydraulic fracking operations and other real-life oilfield applications.
