Brookfield viscometer, the viscosity can be measured working methods of viscometry.

Brookfield viscometer, the viscosity can be measured working methods of viscometry. Viscometers (which can also be called viscosimeters) to measure the test substance in the sample flow conditions over a wide range of viscosity. They work the spindle shaft, which is designed to be dipped or immersed into the liquid, then turn. Rotation is caused by fluid drag, which is measured in terms of torque, fluid viscosity. They are not designed to measure several flow conditions, but it is possible to use instead of the Rheometer.

In order to evaluate the Brookfield viscometer viscosity of the sample, the material must be stationary container, while the shaft moves, while immersed in the liquid. Another option to move the container to the stationary spindle. Regardless of the option, the material must be capable of producing a laminar flow through the shaft while moving. This is possible only with a low Reynolds Number.brookfield viscometer Brookfield viscometer

Reynolds number is a measure that calculates the ratio of inertial forces viscous forces, which are quantified according to a certain flow conditions. Inertia force is measured as PV2 / L, and the viscous force µV/L2. When the number is less, it allows laminar flow to occur during the Brookfield viscometer spindle.
Calibration of the viscometer

Viscometer calibration process is quite simple and uses a standard liquid at a given temperature. This fluid is measured by Brookfield viscometer, and any adjustments that are necessary to known the value of a standard when testing the device.

One of the most common calibration standard liquid is water. Using distilled water is recommended because it does not have any additional electrons, and generally the same every time he measured the exact measurements.

Water 20 degrees Fahrenheit (68 degrees Fahrenheit), is 1.002 units milliPascals viscosity. It also has a kinematic viscosity of 1.0038 millimeters per second squared. When the water is measured through the viscometer, it is the values ??that should be achieved by running the calibration of standardized testing. Anyone can viscometer calibration. Calibration can be mathematically when needed.
The standard types of viscometer

Inline - Inline Brookfield viscometers designed to be installed in a closed system, which often requires the ability to monitor the viscosity. They are often high accuracy and are used in systems that remain closed or a fluid

"Cup" and Bob - and Bob's cup viscometers "cup" to fill a given substance, it is necessary to study. It was basically Bob's shaft rotation device, which has been incorporated into the material and to a certain speed. These viscometers measure the amount of torque that was needed to get Bob to rotate at a certain speed, depending on the cup "cell material, which took place in a manner to provide data that can be quantified. Some of the models, instead of the rotating cup Bob is providing the data, which are due to the precision methods.

Cone and plate - cone and plate type viscometers can be obtained from the shear rate data, as well as the viscosity of the test substance. System requires the use of cone-shaped bob is placed in a shallow angle to the plate with his bare contact.
Stabinger viscometer

Named after the inventor, Dr.. Hans Stabinger used to determine the parameters of the measuring principle was first introduced by Anton Paar GmbH in 2000. It uses a modified rotational viscometer "duvet obtain these values.

"Duvet rotational viscometer can be modified to ensure that reading is similar to the kinematic viscosity value. Cylinder viscometer used Stabinger be hollow and lighter than the weight of the sample. This combination allows the barrel to float during the rotation of the sample and sent to the center and the centrifugal force. It provides a variety Stabinger viscometer friction bearings around a way that provides accurate readings. Measurement of the torque speed 50pNm resolution of the measurement range from 0.2 to 20000 MPa. Density measurements to the dynamic viscosity, which in turn can lead to a kinematic viscosity using the oscillating U-tube system.
Stormer viscometer

Stormer viscometer, which is designed to test the viscosity of the paint and can be used in other areas as well as a specialized type of viscometer. It is widely used in paint industry, to test the viscosity of paint quality.

Viscometer employs the use of specialized paddle shaped rotor that is spun inside the engine. Paddle must be submerged liquid cylinder, then spun trying. Speed ??is adjusted to obtain a fair amount of load the rotor. When speed is reduced, so there is no liquid load, the speed increases the load increases. This simple variation allows for a variety of data, the viscosity of the fluid itself, as well as the optimal parameters for each fluid.

When the load is adjustable rotational speed of 200 revolutions per minute, the viscosity can be determined. Several public tables, for example, was determined by ASTM D 562nd Viscosity value of the Krebs units, which can only be found with various Stormer viscometers. Paints, which are not intended to be applied with a brush or paint roller can not provide enough data for this type of viscometer.
Bubble viscometer

To find the bubble viscometer fluid viscosity fluid known to be used, for example, resin or varnish. Viscometer measures the value is inversely proportional to the measurement of the time it takes the bubble to rise in the fluid. If the bubble rises rapidly through the liquid, then it is characterized by lower viscosity. The same is true for the opposite extreme, if there is a slow bubble, then the viscosity will be much higher within a liquid. Viscosity range, which can be determined through the bubble viscometer 0.005 to 1000 Stokes range. Value can also be extracted from the data in accordance with the time value of 3 different lines, taken from different spheres, and then receive a second reading of the bubble, which can then be converted to Stokes.
