WebViscometer. 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.

WebMar 4, 2024 · Viscosity is a measure of a fluid’s resistance to flow. It can also be thought of as a measure of a fluid’s thickness or its resistance to objects passing through it. The greater the resistance to flow, the higher the viscosity, so for example, syrup has a higher viscosity than water. WebThe change in an oil’s viscosity due to a temperature change is called the viscosity index (VI). Understanding VI is important to discern whether the lubricant in question meets the asset’s requirements based on the operating temperature range. To determine an oil’s VI, the viscosity is measured at two temperatures: 40 degrees C and 100 ... kent county land parcel map
