•
Final installer provided: hoses and fittings are required for external flowmeter connections and water discharge
or recirculation.
• Flowmeter with volume measurement capability, such as provided in the in the AccuMax Calibration Kit (P/N: 3430-0381)
• Final installer provided: container marked for volume, using a container to ensure that it has enough volume capacity
(300G/1000L) to calibrate at least one line. Or, use a scale that measures the weight of material pumped, in order to
calculate its volume.
•
Final installer provided: hoses and fittings to allow foam flow from the calibration valve and manifold to an external
meter or container or foam tank.
Foam System Calibration Procedures
The FoamPro AccuMax II system must be calibrated during initial installation and after major repairs or change in
the foam system. The calibration process allows electronic adjustments to the Fury, Fusion, and APEX displays, water
flowmeters, foam flowmeters, foam line injection assemblies, and low-flow bypass assembly. FoamPro systems can be
calibrated to any unit of measure, i.e., U.S., Metric, Imperial, etc. It is necessary to use the same unit of measure throughout
the calibration process to ensure proper proportioning by the system.
During the calibration process, the foam concentrate tank shall be filled with water for test purposes. Calibration can
be accomplished by using a calibrated external flowmeter, such as provided in the AccuMax Calibration Kit (part number
#3430-0381) or by pumping into a container that is marked for volume or by using the weight of the water pumped. In the
case of using a container, ensure that it has enough volume capacity to at least calibrate one (1) foam-line-injector assembly.
It is recommended to use a container that is at least 300 gallons (1140 liters).
Master Foam Flowmeter, Low-Flow Bypass Flowmeter, and Foam-Line-Injection Calibration
It is important to accurately calibrate the master foam flowmeter, FLI assemblies, and low-end bypass foam flowmeters
must be calibrated to the master flowmeter to ensure the foam system will operate correctly.
•
It is recommended when calibrating the all foam flowmeters to run a small volume of fluid, approximately 25 gallons/95
liters for the first run to make any large adjustments. The second run should be for at least 50 gallons/190 liters to start to
get the calibration closer. The third and every run after should be for at least 100 gallons/379 liters until the differential
between the Master flowmeter and the FLI shall be within at least ½ gallon/1.9 liters.
• Foam pumps and foam systems are tested and calibrated with water (in place of foam concentrate) due to cost and foam
disposal or collection. The viscosity of various foam concentrates may affect the amount of foam concentrate that is
injected into the water stream. When various viscosity foam concentrates are used, the actual concentrate injection may
vary by as much as 15%. It is suggested that the end-user secure a listing of all foam concentrate manufacturers, their
products, percentage, and viscosity.
•
The end-user may specify the foam system be tested with a specific foam concentrate, which would be supplied by the
end-user or final installer.
•
When foam system is installed and calibrated by the final installer, the end-user may wish to adjust the default foam
concentrate injection rate and/or ‘simulated flow rate’ to their special needs. These changes can be made without altering
the calibration by using the procedures described for those functions only in this manual.
