12. CALIBRATION & TESTING
Calibration Procedure Instructions
The Foam Pro AccuMax foam proportioning system relies on sensor readings to control the injection rate of the foam
concentrate into the water stream and for the other system functions. Proper calibration ensures that the system produces
an accurate foam solution and maintains the proper and safe level of foam flow and pressure in its pump and the other
components. During the calibration process, readings from an external reference device will be used to determine the
actual water flow or foam volume discharged. This data will be entered into the system and saved.
Calibration data is stored in the internal non-volatile memory of the hydraulic controller and foam-line-injector
assemblies. For MAX200 models, which use Elkhart electric water valves, the valve position should also be calibrated.
•
Before attempting calibration, make sure the system was correctly installed and configured.
• AccuMax system components can be calibrated in Metric or Imperial units of measure. It is essential to use the same unit
of measure system throughout the calibration process. Once calibration is complete, units of measure can be changed
without affecting calibration.
AccuMax Devices and Sensors That Require Calibration:
•
Master Foam Flow Meter: measures total foam flow produced by foam pump
•
Low-Flow Foam Flow Meter: measures foam flow of foam redirected back to foam pump when low-flow function is active.
•
Foam-Line-Injector(s) Foam Flow Meter: measures foam flow delivered to injection point (discharge).
•
Water Flowmeter (supply data to FLI): measures water flow through discharge to which foam is being injected.
• Fusion System Only -- Electric Water Valve Position on a MAX200: determines water valve position.
Other Auxiliary Devices:
• TankVision Pro Foam Tank Level Meter: measures volume of foam remaining in foam tank
•
External water flow device: capable of measuring water flow (i.e. APEX valve) that is used instead of foam-line-injector
water flow sensor
• Auxiliary Foam Function Devices: for calibration of auxiliary function devices, refer to Chapter #18 or supplemental
information manuals.
Equipment Required for Calibration
The Foam Pro AccuMax system calibration is conducted using the menu system available on Fury and Fusion Displays.
Depending on which device and what type of calibration will be performed, additional equipment will be required that is not
provided with your system.
For Water Flowmeter Calibration:
•
Water flowmeter: accurate external water flowmeter that is capable of measuring flow rates specified for discharge
being calibrated.
