WebFrom Table 3.1, the percent of FSR calculated for accuracy is 2 or 4%, depending on whether the calibration fluid is greater or less than 50% of FSR. If our calibration fluid is 4 Poise, we would calculate accuracy as 2% of FSR, or 2% of 8.333. Instrument accuracy would thus be .1666, rounded to .17 Poise.

Hydramotion Resonant Technology Viscosity Measurement

WebWith a sensor that is designed to protect itself from outside elements, the ViscoPro 2100 is highly insensitive to the outside environment. Its continuous piston motion means that the VP2100 is self-cleaning and can run for years without recalibration. Viscosity Range: 0.25-10,000 cP. Repeatability: 0.5% of reading. Web7 de jul. de 2024 · How does a falling sphere viscometer work? The basic concept is to measure the elapsed time required for the ball to fall under gravity through a sample-filled tube inclined at an angle* . The tube is mounted on a pivot bearing which quickly allows rotation of the tube 180 degrees, thereby allowing a repeat test to run immediately.

WebSuch a viscometer works in the same way as a weight-driven instrument (see the above section). However, the weight is replaced by a driving motor, which realizes high shear stress values (up to 900 kPa) and medium to high shear rates (around 1,500 s-1). A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Thus, a rheometer can be considered as a special type of viscometer. Viscometers can measure only constant … Ver mais U-tube viscometers These devices are also known as glass capillary viscometers or Ostwald viscometers, named after Wilhelm Ostwald. Another version is the Ubbelohde viscometer, … Ver mais Also known as the Norcross viscometer after its inventor, Austin Norcross. The principle of viscosity measurement in this rugged and sensitive industrial device is based on a piston and cylinder assembly.
