Fann viscometer model 35a manual

Model 35 Viscometer Instruction Manual. The Fann Model 35 Viscometer is widely known as the “Standard of the Industry” for drilling fluid viscosity measurements. The Model 35 Viscometer is a versatile instrument for research or production use. In the six-speed models, test speeds of , , , , 6 and 3 rpm are available via. The Model 35 Viscometer is the best known and most commonly used Fann viscometer. The test fluid is contained in the annular space or shear gap between the cylinders. Rotation of the outer cylinder at known velocities is accomplished through precision gearing. The viscous drag exerted by the fluid creates a torque on the inner cylinder or bob.

of time. The Model 35A Viscometer is powered by a Hz motor; Model 35SA Viscometer by a Hz motor. Twelve total test speeds let you measure over an extended shear-rate range. Test speeds of , , , , , 90, 60, 30, 6, 3, and rpm are available via a synchronous motor driving through an SR12 gear box and. Fann manufactures a variety of instruments to test the viscosity of a drilling fluid or mud. Ranging from the simple Marsh Funnel to to rotational viscometers like the industry standard Model 35 Viscometer to the high pressure, high temperature iX77 Rheometer, the Fann line includes an instrument for any drillilng fluid testing need, in the field or in the lab. Fann Viscometer - Model 35A: To measure the viscosity of the mud samples Fann viscometer was used. Before using it for the experiments, the viscometer was calibrated according to the operating manual. Figure 4: Fann Viscometer - Model 35A. Fann Mud Balance - Model Fann - Model mud.

A. Model 35A and Model 35SA The Model 35A and 35SA viscometer are instruments with the ability to test at six different speeds. Their range is from 3 rpm up to rpm with the speed being determined by a combination of speed switch setting and viscometer gear knob placement. To select the desired speed, set the speed.
