The TG-8040 series of Consistometers have wide pressure and temperature operating ranges up to 40,000 psi (275 MPa) and
Both single and dual cell units are available. The dual cell units offer the advantage of a minimum amount of laboratory space. They also offer a slightly lower cost per cell because two pressure cells are combined into one cabinet.
Measuring the thickening time of cement slurries is a fundamental procedure that must be done prior to primary or secondary oil well cementing. The proper technique and procedures are outlined in detail in Section 8 of API Specifications

OPERATIONS
● Operation of the pressurized consistometer is simple with all of the operational controls conveniently located on the front panel. The readout indicators for viscosity, pressure, and temperature are easily read from the panel-mounted indicators and the data plotter.
● The consistometer is designed so that closure, heating, and pressurization can be achieved quickly. This ensures compliance with the requirement of Section 8 of API Spec
● The temperature controller will automatically control the rate of temperature rise of the slurry (temperature gradient). When the slurry reaches the desired maximum temperature, the controller will hold the slurry temperature at that level.
● Pressure is generated with an air-operated high-pressure pump. Control is maintained by adjusting the air pressure to the pump and by operating a pressure relief valve.
● The viscosity ( consistency) of the cement is determined by measuring the torsion generated on a standard torsion spring -- by the slurry pressing against a standard paddle as the slurry container is rotated (in compliance with API Spec |
