<h1>Viscometer of the Invention is Preferably "Duvet</h1><strong> Author: <a href='http://www.articleseen.com/profile_Viscometer.aspx'>Viscometer</a></strong><br /><p>This invention relates in general "duvet viscometer for measuring samples of high pressure and high temperature conditions. More specifically, the invention viscometer designed to improve the use, comfort and care related to the operation of the measure. Rotational viscometers measure fluid shear stress created by well-known shear rates. Viscosity shear stress ratio with shear rate is defined as usually expressed in units of poise. Shear stress is proportional to the torque of a cylindrical object immersed in fluid, surrounded by a concentric cylindrical surface, which is caused by the speed driven. Shear rate is the rotational speed and geometry of the feature. One type of rotational viscometer viscometer "duvet. In "duvet viscometer, the fluid whose viscosity is measured by filling the space between two vertical coaxial cylinders. The inner cylinder is suspended, and the outer cylinder is rotated at a constant speed using a computer controlled stepper motor. The resulting torque on the inner cylinder accurately measured to determine the shear stress. "Duvet viscometers can be used to determine Newton's theological or non-Newtonian solid loaded or not loaded with cool liquid used oil and / or gas wells or treatment completion fluid properties. It is desirable to test such a high temperature and high pressure fluids. In a typical means a pressure vessel can withstand high temperatures and pressures must be a cup of viscometer and BOB. After the tests are carried out in a pressure vessel to be removed from the device to change the sample fluid and clean the components. Viscometer of the invention is an example of pressure vessels and plug assembly. For an example of the restriction can be heated and pressurized to simulate the conditions of oil or gas wells. When these conditions are stable, the sample viscosity is determined by measuring the shear stress-known shear rates. Viscometer of the invention is preferably "duvet, type, and can be used to determine the rheological properties of Newtonian or non-Newtonian solid loaded or not loaded with cool liquid used in oil and gas well completion fluids or treatment. A facility capable of measuring heat, for example, 600 ° F and pressure of the sample properties, such as., 30,000 PSIG., Temperature, pressure and shear rates of diversity. The specimen is a pressure vessel inside the sample cup. Sample cup of liquid helps to separate the sample fluid pressure and helps to remove the sample collection when the plug is removed. The sample container is a magnet assembly, such as SmCo magnet assembly, rotor assembly and Thermowell bearings and bushings. Bob's collection of jewel bearing pivot. Collection of pairs of opposite magnetic magnet assembly that is located outside the pressure vessel, for example., 2. SmCo magnet assembly. By rotating the outer magnet assembly known speed using a stepper motor, motion capture, and an inner magnet rotor causes. Thermowell provides tools to accurately measure the temperature of the sample collection by Bob's collection of mid-range. The sample container is balanced by the high pressure port to connect to the internal and external pressure in the volume. Thus, the sample cup is not to resist the pressure and can be produced with low weight. The outer surface of the cylindrical tubes to improve the use and improve heat transfer. External rotor assembly screw flutes, which are used to cause the circulation of the sample rotor assembly is rotated. The circulation path is a ring-shaped volume of the rotor assembly, baffle, sound ring Bob at meetings, airports, hotels, conical at the top of Bob's meetings, and the volume around the magnet assembly. Over Bob's Silencer assembly is used to eliminate or reduce the angular momentum of the sample caused by helical flutes. The torque from the calculated shear stress determined by sensing angular displacement and the spring, for example, a linear spring, BECU, Bob is attached to the assembly, in a closed tube, a pressure vessel. Spring angular displacement is measured using high-resolution optical encoder, magnetic connection to the magnet assembly, for example. SmCo magnets produced by the spring. During the calibration of the spring, the angular displacement is related to torque and shear stress. To reduce the increase in frictional effects of the torque measuring the sensitivity of the optical codewheel during assembly coding, sapphire jewel bearings.</p><strong>About the Author:</strong><br />Visit viscometer.co for all types of <a rel="nofollow" href="http://www.viscometer.co/">viscometer</a> according to your need.<p> Article Source: <a href='http://www.articleseen.com/Article_Viscometer-of-the-Invention-is-Preferably-Duvet_145422.aspx'> http://www.articleseen.com/Article_Viscometer of the Invention is Preferably "Duvet_145422.aspx</a></p>
