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 manufacturing 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 paint line where robots apply the color and clear coats to primered car bodies. Nissan process engineers required intrinsically safe, non-contact level measurement and were concerned about the negative effects of splashing on the sensors. For this reason, Flowline suggested the use of our EchoTouch ultrasonic level sensor installed in an unusually tall riser mount. The risers eliminated the possibility of paint reaching the sensors and was acceptable in this application due to the short measurement range. Forty-four ultrasonic sensors provide reliable level data to the PLC, which in turn, controls the tank batching, mixing and pumping processes. Flowline is reliable level measurement. |
