Graco Reactor 2 Ratio Assurance
Graco's Multi-Tiered Ratio Assurance System
1. Mechanically Linked Pumps
2. Positive Displacement Piston Pumps
3. Outlet Pressure Monitoring
4. Flow Meters
5. Inlet Pressure Monitoring
Single-Point Variables
Any issues that may cause off-ratio foam to be sprayed are called Single-Point Variables.
Since no one detection method is best to detect all possible issues, it is important to have a robust, multi-tiered ratio assurance system that incorporates both pressure and flow meter monitoring.
Single-Point Variable Categories
- Air in the fluid stream
 - Feed pump too small
 - Poor material feed to the proportioner
 - Proportioner pump issues
