The determination liquid in the certain temperature, under the volume condition, flows out the time from the Engler viscosimeter (the second ] with the distilled water the time which leaves in 20 ℃ fashion (the second ] the ratio, for this liquid relative viscosity, namely Engler viscosity, unit for condition.ģ. The Engler viscosimeter is determines the petroleum product and other liquid relative viscosities gaging instruments, widely uses in the factory, the laboratory, the geological field ty and so on. This instrument acts according to ASTMD 1,665, the IP212 standard determination emulsified bitumen and the coal tar graciousness standard pulls the viscosity. The petroleum product Engler viscosimeter (number reveals): Ĥ、special thermometer: In accordance with GB514-75;ħ、 inner test vessel: stainless-steel wall; The ratio of two different time with which the measured fluid and 20℃ water flow through the orifice in the bottom is called Engler Viscosity of the fluids( in Ev) on the condition of the set volume and temperature. It is widely used to determined viscosity of various liquid such as oil, paint, food, medicine, adhesive, etc in the filed of petro chemistry, medicine, food, light industry, textile industry, scientific research, etc.Īccording to《Viscosity Tester by Engler Specific》, the viscometer is made and can cover the determination of the Viscosity of the fluids. 1-4 and can be chosen to use in accord with viscosity of the liquid to be determined rotation speed. V-1 rotational viscometer is one kind of the viscosity meter used to measure/test the viscosity resistance and absolute viscosity of liquid. It is controlled by microprocessor,so the operator may directly read out the KU values of the tested samples from the display and do not need to look up the table. This digital Stormer viscometer is an instrument applicable to determine the viscosity of the paints and other coating materials that are expressed in KU values.It is rotational shear-type viscosity meter.The design of the viscometer is based on the standards ASTM /D 562-81 and GB/T9269-88. Rotating bobs are more common, rotating cups reduce the likelihood of vortex formation, and "cone and plate" viscometers create a constant shear rate at any speed.Viscosity meter with KU measurement parameter: Rotational viscometers use the concept of torque to measure the effort required to turn a disk or bob in a fluid.This can be done electronically for opaque fluids. Falling ball viscometers measure the time it takes for a sphere of a known size and density to descend through a stationary liquid.You calculate viscosity by measuring the amount of time it takes for the liquid to move between two marks. Liquid is drawn by suction into the upper bulb and allowed to flow down into the lower bulb. For Kinematic Viscosity from 10 ☌ to 150 ☌ ASTM D445/D446, ISO 3104/3105 Precise & accurate temperature control - Temperature range: 10 ☌ to 150 ☌ - Temperature accuracy: ± 0.01 ☌ from 10 ☌ to 100 ☌ ± 0. Glass capillary viscometers or Ostwald or Ubbelohde viscometers consist of a U-shaped glass tube held vertically in a controlled temperature bath.What Are the Different Types of Viscometers? Viscometers measure using a single flow condition. In general, viscometers move an object through a stationary fluid or move the fluid past a stationary object to measure the friction between the fluid and the object or surface. An example is the slower flow of syrup from a container - syrup is more viscous than water. Viscometers are instruments used to measure viscosity, the internal friction of the layers of a liquid in motion. Viscometers or viscosimeters are important to many industries, including the adhesive, biotech, chemical, food, paint, petroleum, and pharmaceutical industries. Instruments used to measure the viscosity of a fluid available in a variety of configurations.
