Non-Contact Ultrasonic Flow Sensors in Coating Fluid Management: Revolutionizing Precision and Efficiency
In TFT-LCD conductive layer coating, a mere 0.5μm thickness deviation can cause batch-wide brightness unevenness. For lithium battery electrode coating , ±2% slurry flow fluctuation may trigger thermal runaway risks. These real-world scenarios highlight the criticality of flow control in coating processes. Discover how ultrasonic flow sensors address core challenges in coating fluid management. Critical Flow Control Challenges in Coating Processes 1. Micron-Level Precision Loss - In roll-to-roll coating, slurry flow fluctuations exceeding 1.5% cause ±3μm thickness variations in battery electrodes, directly impacting energy density (Data source: 21700 battery production line ). - Case study: A 0.8-second latency in an OLED mask coating system generated 15 defective panels hourly. 2. Contamination-Sensitive Fluids - Traditional turbine flow meters caused 0.3% monthly material contamination in UV adhesive c...
