What is difference between LVT and RVT Viscometer?..

Answer / Yashpal Panwar

LVT (Linear Velocity Transducer) and RVT (Rotational Viscometer) are different types of viscometers used to measure the flow behavior of fluids. The main difference lies in their operational principle:
1. LVT: Measures the velocity of a fluid as it moves through a known gap between two plates, providing a linear relationship between shear stress and shear rate.
2. RVT: Measures the torque required to rotate an immersed spindle within the fluid, which is then used to calculate the viscosity of the fluid.
