Surface coating for noise dampeners
To measure the flow rate of an adhesive coating, commercially available best in quality flow meters were previously used to mix the filler with a powder component.

To measure the flow rate of an adhesive coating, commercially available best in quality flow meters were previously used to mix the filler with a powder component. However, due to the powder component, the meters would wear out and the reliability systematically deteriorates. The expected accuracy was no longer achieved and the end product did not meet the standard required by the car manufacturer. Due to the high rejection rate, which was found in the incoming goods inspection of the customer, high damage was caused, both for the manufacturer and the end customer. High penalties for the manufacturer were the consequence, as the lack of quality caused the end customer to delay delivery. A solution was sought to solve this costly problem quickly and efficiently.
An installed monitoring system was tested in combination with a Coriolis mass flow meter and met the quality requirements. At the same time, there is no need for costly maintenance, because there are no moving parts, which can wear out, thus ensuring long-term accuracy.
