Rolling Ball Viscometer

Manufacturer: Vinci Technologies
Model Number: RBV-1000

The rolling ball viscometer is designed to determine the viscosity of bottom-hole and surface oil samples at elevated temperature and pressure. It uses the rolling ball principle where the roll time of a ball is used to obtain viscosity data. Viscosity values are then obtained by correlation of the measured data with curves of fluids with known viscosities. The RBV 1000 consists of a calibrating barrel equipped with a latch at its upper end and an detector at its lower end. The latch permits to trap and release the ball while the detector detects the arrival of the ball allowing the roll time to be determined. The viscometer features a jacket for circulating heating fluid around the chamber to ensure a constant and homogeneous temperature of the sample.
