Pressurized Foam Rheometer

Manufacturer: Vinci Technologies
Model Number: RHEO F400

The pressurized foam rheometer Rheo F400 is a fully automated pipe rheometer designed specifically to measure the rheological properties of foamed fluids under pressure and temperature conditions over a wide range of foam qualities, shear rates and shear stresses. The system incorporates three high pressure – high temperature syringe pumps for injection of the base fluids and collection of the foamed fluid. Pressure transducers are provided to cover a wide range of shear stress measurements. Flow rate and shear rate of the foamed fluids are measured using a Coriolis mass flow meter. The shear loop is contained within an air bath enabling uniform temperature control of all components within the loop. An integrated high-pressure capillary sight glass cell allows visual determination of the foamed fluid while a video system captures pictures of the foam through the view cell. The software is designed to allow the operator control over foam quality, shear rate, shear stress, time length of tests and operating temperature.
