The sizes of the units are such that vis- Calibration of Capillary-Type ViscosimetersDetermine cosities in the ordinary ranges are conveniently expressed inthe viscosimeter constant, k, for each viscosimeter by the centistokes.(plate) Automatic Kinematic Viscometer(steel) fluids is by using capillary viscometers. With capillary viscometers, viscosity is determined based on the flow time of a fluid which is kept at a specific temperature inside a capillary with known diameter and length. Viscol-10 Series, fully-automatic kinematic viscometers, equipped by the latest temperature control, detector,(plate) Cambridge Viscosity FAQs for Viscosity 101(steel) The capillary viscometer measures the time for a fluid to flow between two points in a glass capillary that has been placed in a temperature controlled bath. The oscillating piston method, sometimes referred to as Electromagnetic Viscometer or EMV viscometer, uses a sensor comprised of a measurement chamber and magnetically influenced piston.
Other articles where Capillary tube viscometer is discussed viscometer In the capillary tube viscometer, the pressure needed to force the fluid to flow at a specified rate through a narrow tube is measured. Other types depend on measurements of the time taken for a sphere to fall through the fluid, or of the force needed to(plate) Capillary viscometer Article about capillary viscometer capillary tube viscosimeter glass capillary kinematic(steel) The solution viscosity method requires relatively simple equipment--a glass capillary viscometer. However, expensive laboratory facilities and high level laboratory staff are required to facilitate the use of dangerous solvents.(plate) Cited by 33Publish Year 1972Author J GlassPHM2213 Practical Viscometry_Capillary.doc - PHM2213 capillary tube viscosimeter glass capillary kinematic(steel) To obtain readily measured flow times, viscometers with narrow capillary tubes are used for liquids of low viscosity, while wider capillary tubes are used in viscometers for high viscosity liquids.

Glass Capillary Viscometers. Viscometers VPZh-1, VPZh-2, such as Pinkevich, VPZhM, and for opaque liquids, are used to measure the viscosity of transparent liquids. The kinematic viscosity of the liquid v is equal to the product of the time t flowing out through the capillary of a certain volume thereof and the constant of the viscometer C.(plate) File Size 283KBPage Count 24Laboratory Kinematic Viscometers , page1.(plate) File Size 86KBPage Count 9Capillary Viscometer at Thomas Scientific(steel) BS/U Tube glass capillary viscometers are ideal for measuring the kinematic viscosity of transparent Newtonian fluids within a range of 0.9-10,000 cSt. Includes a calibration certificate with a Constant values at 40°C and 100°C and a precision of ±0.2%.

GLASS CAPILLARY VISCOMETERS for the MEASUREMENT of KINEMATIC VISCOSITY VERIFICATION METHOD 0. Scope This Recommendation sets out the method and means for initial and subsequent verifications of glass capillary viscometers (ordinary instruments), free liquid flow, intended for the measurement of kinematic viscosity of liquids.(plate) Measurement of the internal diameters of metallic capillary tube viscosimeter glass capillary kinematic(steel) thad ceased entering the capillary tube, the tube was Withdrawn from the merc. my, but the end was kept within the reservoir. By gently warming the capillary tube, several drops of mercUTY were ex pelled and returned to the reservoil. Upon cooling, t' this left an ail, space several inches 1 ng near the end of the tube.(plate) Measuring Oil Viscosity - Spectro Sci(steel) May 20, 2019Typically, ASTM D445 methods are run in a laboratory setting due to the glass capillary tubes and large constant temperature baths which are difficult to maintain in the field. Spectros MiniVisc 3000 is able to quickly perform kinematic viscosity with only a few drops of oil and the results are reported in centistokes per ASTM D8092.

In this case, the fluid passes through a fixed diameter orifice under the influence of gravity. The shear rate is less than 10 s-1. The kinematic viscosity of most lubricating oils is measured by glass capillary viscometers.
