When Renault in Hubei, China needed reliable level measurement of their paint mix tanks, they turned to Flowline. Designed by Nissan and built by Dongfeng, the plant produces 150,000 sport utility vehicles a year. During which, solid and metallic enamel paints are continuously batched, blended and pumped from the paint room to the line where robots apply the color and clear coats to primered car bodies. Their engineers required intrinsically safe, non-contact level measurement and were concerned about the effects of splashing on the sensors. For these reasons, Flowline suggested our LR20 ultrasonic sensor installed in a tall fitting to eliminated the possibility of paint reaching the sensors. Forty-four ultrasonic sensors provide reliable level data to the PLC, which controls the paint batching, mixing and pumping processes. Flowline is reliable level measurement. |
