Order of Calibration Process
Calibration process can be divided into two groups:
•
Water Flow Calibrations for each water flow meter in system
•
Foam Flow Calibrations for master flow meter, low-flow line and injectors
Each calibration group can be performed independently of the other and in any order.
Water Flow Calibration Requirements
The process will require running water pump and operating water valves, along with moving hose connections from
each water outlet to an external flow metering device. Calibration of water flow meters must be done for each discharge
and can be done in any order.
NOTE: If the system is equipped with Fusion Displays, associated water valve position needs to be calibrated
before
water flow calibration. Follow instructions for Water Valve Calibration.
Water Flow Calibration Injector Process
In order to conduct water flow calibration, an external reference flowmeter shall be connected to the discharge being
calibrated. Actual water flowing out of that discharge will be measured by a reference meter. This reading will be entered
as a calibration data point into the system.
1.
Single Point Calibration:
In most installations, only one data point is needed for water flow calibration. During
single point water flow calibration, use typical flow rate that would be used for this discharge during firefighting.
2.
Multi-Point Calibration:
In case accurate water flow measurements are not possible to achieve with single
point calibration, additional data point(s) can be added for different flow rates during the calibration process. A
maximum of (9) nine data points can be added. Flow rates used for each data point must be varied from those
already entered by at least 5%. An invalid data point will be rejected.
Before calibration can start, make sure all hose connections are secure and without restrictions and bends. Assure
water has a safe way to discharge out of the equipment or is looped back to the water supply. Engage and run the water
pump at a pressure that does not exceed the pressure rating of any component in use.
