Model 6500-M Friction Flow Mini-Loop™

Model 6500-M Friction Flow Mini-Loop™

The Chandler Engineering 6500-M Mini-Loop™ bench top system is designed to allow rapid test turn-around for the repeat testing of stimulation fluids.

Friction Flow Mini-Loop System

The Mini Flow Loop circulates fluid through a single test section and uses custom software to record and analyse the test data. This enables reliable testing in a simple to operate, compact system. This model is ideal for Quality Control Testing of Slick Water Fracturing Fluids.

The Mini Flow Loop system incorporates a low shear, progressive cavity pump for circulation of base fluids. A differential pressure transmitter measures the friction pressure across the test section. The friction reducing agent is added directly into the 19 litre reservoir mixing tank.

Designed to be user-friendly, the software collects all required data during the test cycle for use in friction reduction calculations. Data may be stored in a test-specific .CSV file for analysis.

Optional add-on module to enable real time display of flow rate and fluid density.
