Torque-Spring Indicator Atmospheric Consistometer Part No. 800.5938
DESCRIPTION: The Halliburton Atmospheric consistometer is used extensively in oilwell cement testing applications for the following:
determining water requirements for cements and additives
determining cement slurry viscosity
preconditioning cement slurry before fluid-loss, free-water, or rheological testing
measuring thickening time of slurries for shallow wells having low temperatures and very low pressure. (If the well pressure is very high, the thickening time measured at atmo-spheric conditions will be longer than the actual available thickening time under pressure conditions. This unit is not intended to be used in place of the High-Temperature/High-Pressure Consistometer because of the strong influence of pressure on the thickening time of a cement slurry.)
OPERATION: Slurry containers rotate in a water compartment containing a submerged heat-ing element. Fluid viscosity is measured by the drag caused as the slurry cup rotates around a stationary paddle affixed to the slurry-viscosity indicating-lid of the slurry cup. This drag is transferred to a coil spring in the indicating lid or to a weighted torque arm, both of which are calibrated to measure Bearden units of consistency. This measurement is indicated by a pointer and viscosity scale on the unit.
