Inline Paint Viscometer

Short Description:

The inline paint viscometer is a continuous viscosity measurement instrument to measure viscosity of paints, coatings, and inks directly in pipelines or tanks, ensuring perfect color, finish and consistency in real time. Through instantaneous and accurate viscosity readings, inline viscometer paint allows for automated adjustments to solve addition or temperature, eliminating manual cup checks and preventing defects like sagging, orange peel, or uneven film thickness. The inline viscosity meter for paint could be integrated into mixing, blending or dispensing systems seamlessly.

Product Detail

Product Tags

It's also known as an inline ink viscosity meter or inline viscosity meter for ink for its outstanding performance in ink production lines. It's commonly installed in the supply line pipeline that carries ink from the main reservoir/tank/pump to the doctor blade chamber or the ink pan, providing immediate feedback on the ink viscosity just before it reaches the anilox roller or gravure cylinder. Looking into its working principle and see how it works in automated process control.

Working Principle

The inline paint viscosity meter consists of a sensor probe and a transmitter, designed for installation in reactors, reaction tanks, or pipelines to measure liquid viscosity in real time. It employs a solid rod-shaped sensing element that vibrates sinusoidally at a specific frequency, oscillating torsionally along its axis. The sensor features a single exposed element, enabling free fluid flow across its surface. As the element shears through the fluid, it experiences energy loss due to viscous drag forces, which vary with the fluid's viscosity resistance. This energy dissipation is detected by electronic circuitry and processed by the transmitter to generate a readable viscosity value.
