	Viscometer - Wikipedia, the free encyclopedia
		Glass tube viscometers can have a reproducibility of 0.1% under ideal conditions, which means immersed in a fluid bath, but are not ideally suited for measuring fluids with high solids contents, or viscosity.
		The common Brookfield-type viscometer determines the required force for rotating a disk or bob in a fluid at known speed.
		Viscometers that can measure fluids with high viscosity or molten polymers are usually called rheometers or plastometers.

		Thus, the viscometer is an instrument which measures consistency of gases, and Newtonian and non-Newtonian fluids.
		The capillary-tube viscometer also gives kinematic viscosity in stokes from measurements of the pressure gradient and of the volumetric flow rate in a cylindrical tube of precisely known dimensions as stated by the Hagen-Poiseuille Law for the flow of fluids through a capillary.
		The capillary-tube viscometer consists of a fluid reservoir to hold a specific volume of sample liquid and of a capillary tube.

	viscometer- read about various viscometer.
		Efflux cup viscometers are most commonly used for fieldwork to measure the viscosity of oils, syrups, varnish, lacquer, paints, and bitumen emulsions, although they ahve some inherent inaccuracies.
		The testing procedure of efflux viscometer is quite similar to the capillary-tube viscometers where efflux time of a specified volume of fluid is measured through fixed orifice at the bottom of a cup to represent the viscosity of the fluid.
		The operating principle of the rotational type viscometer is based on the fact that the torque necessary to overcome the viscous resistance to teh induced movement (torque) by rotation of a spindle is directly proportional to the viscosity of the fluid.

	Viscometer - Patent 4175425
		The viscometer of claim 1 in which the tube is stainless steel tubing having an outside diameter of approximately 0.080 inches and a wall thickness of approximately 0.005 inches and the diameter of the readout rod is approximately 0.062 inches.
		That type of viscometer has open ended cylinders within the liquid the viscosity of which is to be monitored, one cylinder with the inner cylinder driven by the medium in the space between them in response to the turning of the driving cylinder.
		With the viscometer in use and the motor 24 in operation the liquid flowing between the two cylinders exerts a rotative force on the drive cylinder 48 that increases with the viscosity of the liquid.

	FALLING BALL VISCOMETER
		The viscometer is supplied with a glass ball and a stainless steel ball (type 316).

	Drilling Fluids - Viscometer Comparison (Site not responding. Last check: 2007-10-13)
		The measuring geometry (concentric cylinders) of the RJF viscometer is designed to quantify the viscosity of non-Newtonian drilling fluids.
		The low shear rate viscometer traditionally used was originally designed for use with Newtonian liquids, and its use with drilling fluids warrants caution because shear rates cannot be directly determined.
		The accuracy of this measurement is dependent upon the ability of the viscometer to accurately quantify both shear stress and shear rate.

	[No title]
		After years of measuring viscosity with an off-line unit and being dissatisfied with both the results and the maintenance requirements of the instrument, personnel at Rea began to look for an in-line solution about five years ago.
		Rea was attracted by a new viscometer developed and produced by Cambridge Applied Systems, Inc. (CAS) of Medford, MA.
		The plan was to ease into the new system by hooking the viscometer up in a monitoring capacity first and then adding a PID controller to automated the solvent addition when all personnel were comfortable with the new approach.

		The Synchro-Lectric Viscometer rotates a cylinder or disc in a fluid and measures the torque necessary to overcome the viscous resistance to the induced movement.
		This is accomplished by driving the immersed element, which is called a "spindle", through a beryllium copper spring - the degree to which the spring is wound, indicated by the position of the red pointer on the Viscometer's dial, is pro- portional to the viscosity of the fluid for any given speed and spindle.
		The Viscometer is powered by a General Electric synchronous inductor type motor, 5SMY2OJ.
