The Model 60 Atmospheric Consistometer is used for conditioning cement slurries as specified within API Specification 10. Determination of rheological properties, examination of free water content, and evaluation of the API fluid loss test all require that the cement slurry be pre-conditioned by an atmospheric consistometer. The OFITE Model 60 was specifically developed to perform these duties.
Method of Operation:
A cement slurry is prepared according to the procedures as outlined within API Specification 10 and then placed within the slurry containers of the consistometer. The slurry is stirred at 150 rpm by an API-designed paddle while the temperature is increased to the desired level. The temperature is controlled by a micro-processor, which displays the process temperature via a digital indicator. Consistency, measured in Beardon Units (Bc), is determined by measuring the deflection of a calibrated spring. This deflection is created by the amount of torque the cement slurry exerts upon the paddle and is a function of the consistency of the cement. The API defines 100 Bc as 2,080 gm-cm of torque.
