FAQ
Q: What is ratio controller?
Ratio controller is a device that automatically mixes a precise percentage of foam concentrate with water to generate firefighting foam. It ensures the correct ratio for effective fire suppression.
Q: How does a ratio controller work?
It uses the venturi principle or a mechanical balancing mechanism to create a pressure differential that draws foam concentrate into the water stream. The mixture then forms a foam solution.
Q: What are the common types of foam ratio controllers?
Venturi-type controllers
Balanced pressure proportioners
Inline balanced pressure proportioners
Bladder tank systems with ratio controllers
Q: What foam concentrate percentages are supported?
Most controllers are designed for: 1%, 3%, 6%. Check the model specifications to confirm.
Q: How is the correct proportion maintained
The system is calibrated based on flow rate and pressure. Some systems include flow meters or pressure regulators to ensure the correct mixing ratio.
