Original sentence: However, their mechanical robustness and freedom from small gaps that could be plugged by suspended particles in the fluid to be measured makes them useful for measuring viscosity in continuous industrial processes
Edited sentence: Actually even the very basic or acid fluid can be measured by adding a special coating or by changing the material of the sensor such as 316L, SUS316, Hastelloy, enamel etc....Currently, many industries around the world consider these viscometers as the most efficient system to measure viscosity of any fluid, contrasted to rotational viscometers, which require more maintenance, inability to measure clogging fluid, and frequent calibration after intensive use.Some companies have devices based on vibrating blades or other vessels, following the original designs patented by SOFRASER.The active part of the sensor is a vibrating rod.The vibration amplitude varies according to the viscosity of the fluid in which the rod is immersed.These viscosity meters are suitable for measuring clogging fluid and high-viscosity fluids even with fibers (up to 1,000,000 cP).Vibrating Viscometers: SOFRASER product line of vibrating viscometers.Vibrating viscometers are rugged industrial systems used to measure viscosity in the process condition.Vibrating viscometers has no moving parts, no weak parts and the sensitive part is very small
