Model 6500 Friction Flow Loop System

Model 6500 Friction Flow Loop System

The Chandler Engineering 6500 Friction Flow Loop is a fully automated system which includes the necessary hardware and software to measure the friction pressure of different fluids. It can, therefore, be used to determine the effects of friction reducers on fluids over a wide range of pressures and flow rate conditions and through different pipe diameters.

Friction Flow Loop System

The 6500 Friction Flow Loop system circulates fluid through two test sections of various diameters in order to generate differential pressure versus flow rate data. This data helps to determine the effectiveness and longevity of various friction reducing agents added to the test fluids.

The system incorporates a low shear, progressive cavity pump for injection of base fluids with the flow rate controlled by a Coriolis flow meter. Differential pressure transducers are provided on each tube diameter, allowing for multiple data readings per test. Fluid can be injected into the flow stream via an optional metering pump or added directly into a 55 litre reservoir mixing tank.

The software is designed for ease of use and is powerful enough to calculate and collect all required data during the test cycle. The software gives the operator total control over the flow rate, test time and temperature (optional) of each individual test. A .CSV file for analysis is created which stores all the data and test parameters.
