During the manufacturing process, fixed-ratio pumps dispense a specified resin-to-catalyst ratio to ensure accurate curing of the molded panels. Without a verification method, production lines were forced to stop when pumps were not on ratio, resulting in downtime and lost yields.

AW-Lake worked with the OEM and the PLC integrator to solve the off-ratio issue. The solution is the  TRICOR Coriolis flow meter. One Coriolis meter monitors the amount of the four resin colors, and another meter is used to monitor the catalyst. Each meter was networked into a multidrop Modbus network, which was connected to a PLC. The PLC-based monitoring system utilizes the pulse output from the Coriolis flow meters to calculate flow for monitoring the resin-to-catalyst ratios in real time.
