Definition of In-Line pipe viscosity monitoring system
In-Line pipe viscosity monitoring system
The In-Line Pipe Viscosity Monitoring System (In-Line Viscosity Meter) is a crucial piece of equipment used in battery manufacturing processes to monitor the viscosity of fluids in real-time. Viscosity is a physical property that represents the resistance to flow of a fluid, and it is a key factor in determining the quality and performance of the fluid. The In-Line Viscosity Meter is a system that measures the viscosity in real-time by utilizing the pressure difference caused by flow rate when slurry is transported through pipes. It is applicable to complex piping systems and die flows containing non-Newtonian fluids, including battery slurry, binder solutions, and polymer liquids.
Principle of In-Line Viscosity Meter
The In-Line Viscosity Meter is installed inside the pipe through which the fluid flows and measures the viscosity of the fluid in real-time. The measurement principles are as follows
Vibrating Viscometer
A vibrating viscometer measures viscosity by using a vibrating tube or probe. It calculates the viscosity of the fluid by observing changes in the frequency of vibration. Monitoring frequency changes is the core technology.
Rotary Viscometer
The In-Line Viscosity Meter is installed inside the pipe through which the fluid flows and measures the viscosity of the fluid in real-time. The measurement principles are as follows
Pressure Drop Viscometer
This method calculates viscosity by measuring the pressure drop that occurs when the fluid passes through a narrow section. Viscosity is determined based on the fluid's cross-sectional area and the trend of pressure changes. This method reflects the flow state of the fluid.
Real-Time Solids Measurement
(Sample measurement rate: 10 times/sec, 50 samples averaged over 5 seconds)
By applying microfluidic technology to control the flow of fluid through fine channels, precise viscosity measurements are possible. The advantage is maintaining high accuracy with small sample volumes.
Ultrasonic Impedance Measurement Based on Solids Concentration
Viscosity is measured using ultrasonic waves. This technology operates in a non-contact manner, making it resistant to contamination and wear. It allows for fast and accurate measurements and is applied as a key core technology.
Enhanced Solids Measurement Accuracy Through Simultaneous Ultrasonic Measurement
By using ultrasonic waves of various frequencies, the response according to the size and concentration of solids can be analyzed, enabling more precise measurements. Advanced signal processing technology is applied to minimize noise and enhance signal accuracy.
