Model Number: RBV-1000

The rolling ball viscometer determines the viscosity of samples collected either down hole or at the surface. It uses the rolling ball principle where the travel time of a piston is used to obtain viscosity data, which are derived from correlation with curves of fluids with known viscosities. The RBV 1000 consists of a calibrated barrel equipped with two laser detectors at each end and a latch at its upper end. The latch holds and releases the piston while the lasers detect its departure and arrival, thereby allowing the travel time to be determined. A homogeneous, constant temperature profile is ensured by virtue of a heating mantle wrapped around the barrel. A computer system acquires the falling time and calculates the viscosity value.
