In the automotive industry, cavities in the body and underbody must be effectively and permanently protected against corrosion. For this purpose, waxes are injected into the corrosion-prone areas by means of injection nozzles and lances of robots.
Volume-controlled dosing systems are used to ensure the right dosage for each sealing process. These flexibly meet all requirements of functional dosing.
The partially highly filled and thus highly viscous media typically applied in underbody protection, sill application and seam sealing require a robust measuring system of the highest quality that also generates the lowest possible pressure losses.

KEM Helical Flow Meters (SRZ Series) are used for flow measurement in in cavity preservation and car bodie sealing applications. Due to their robustness and low pressure loss they are used for process monitoring. In addition, the use of materials can be minimized to an optimum.
