Based on the vibrating-element theory, density and viscosity meters measure the relationship between vibration frequency and fluid density.
In order to calculate the viscosity of a liquid, viscosity meters monitor other frequency characteristics in addition to this operating concept. To account for variations in metal stiffness brought on by temperature fluctuations, all density and viscosity meters record their internal temperatures.
Utilizing densitometers and viscometers, density and viscosity are important process variables that may be used to evaluate efficiency, determine product interfaces, determine product quality, conduct mass-to-volume conversions, and more.
Anywhere the value, quality, or composition of a liquid, gas, or slurry is significant, density and viscosity measurements are required. Determining a liquid, gas, or slurry's identity, amount, and accuracy of measurement are all made possible by density and viscosity measurements.
For every liquid, gas, or slurry operation requiring custody shift, interface detection, blending, separating, evaporating, or product change, densitometers and viscometers are essential.
These meters contribute to increased income by providing better results when measuring the density of crude oil, the percent concentration of a caustic cleaning solution, or a sugar-water mixture (degrees brix).
