![]() This analysis will allow the operators to optimize the refining process and therefore lower production costs while improving product quality. Therefore, refineries require a reliable and accurate viscosity analysis system to meet the required specifications. Given today’s highly competitive environment, oil refiners are demanding instrumentation that aids in the optimization of the refining process. With the end user in mind, attention to design detail allows for ease of maintenance previously thought unattainable by conventional systems. This updated design combines traditional, reliable oil bath viscosity with key systems control upgrades. The result is an unsurpassed, high-quality viscosity measurement system that produces the process control signal required to perform today’s optimized and cost-efficient petroleum refining operations. The Model P-950 Viscosity Index Analyzer is the result of combining the latest, state-of-the-art technology with over 45 years of industry experience. Quickly verify meter health and status using advanced. To measure viscosity under a high shear rate Cone and Plate viscometers are available. The viscometer product line can measure viscosity from a near water-like viscosity to a very high viscosity range for epoxy, sealants, and paste. Expand usage with a hazardous area-approved, head-mounted transmitter that supports local configuration and display. For laboratory viscosity measurement BYK-Gardner offers a comprehensive line of rotational viscometers. Easily insert directly into pipelines, bypass loops and tanks. Superior repeatability exceeding ASTM D-445 and D-2270 Receive reliable and continuous multivariable measurement of viscosity, density and temperature. 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.Customizable 2-4000 cP Sample Range (optional kinematic output in cSt)Ĭontinuous Sample Viscosity and Viscosity Index outputĭoes not require atmospheric recovery system 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. You calculate viscosity by measuring the amount of time it takes for the liquid to move between two marks.įalling ball viscometers measure the time it takes for a sphere of a known size and density to descend through a stationary liquid. Liquid is drawn by suction into the upper bulb and allowed to flow down into the lower bulb. 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? Falling ball viscometers measure the time it takes for a sphere of a known size and density to descend through a stationary liquid. Angle measurement sensors are created on. The modification of molecular rotors towards increased cell membrane association provides a new research tool for membrane viscosity measurements. You calculate viscosity by measuring the amount of time it takes for the liquid to move between two marks. paper, classification and applications of Fiber-optic sensors (FOSs) are discussed. Viscometers measure using a single flow condition. Liquid is drawn by suction into the upper bulb and allowed to flow down into the lower bulb. 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. PCE-RVI 1 is an analogue viscometer or dial reading viscometer used in industrial and research applications to measure the viscosity of fluids such as paints, lacquers, inks, pastes, adhesives, plastics, greases and liquid food products.
