Why Test the Pressure and Flow of Outdoor Fire Monitors
Outdoor fire monitors are often fixed installations in ports, chemical plants, warehouses, oil depots, and large storage areas. Their reliability directly affects fire suppression efficiency.
By performing pressure tests and flow tests, operators can detect pipeline blockages, insufficient water supply, or worn components early — ensuring that the fire monitor delivers accurate, long-range, and reliable performance during emergencies.
Common Equipment for Testing
Testing usually involves both fixed devices and auxiliary equipment:
Pressure Gauge
Installed at the water inlet of the fire monitor or on the pipeline.
Monitors the real-time inlet pressure.
Typical range: 0–1.6 MPa or higher.
Flow Meter
Portable or inline type, used to measure water flow (L/s or m³/h).
Common types: electromagnetic flow meters, turbine flow meters.
Step-by-Step Guide: Pressure and Flow Testing
1. Preparation
Ensure the water supply system and fire pumps are working properly.
Check monitor valves, connections, and hoses for damage.
Install a pressure gauge at the inlet and a flow meter at the outlet or pipeline.
2. Pressure Test
Open the supply valve gradually and increase pressure.
Read the inlet pressure from the gauge.
Compare with the rated operating pressure (e.g., 0.8–1.2 MPa).
If pressure is below standard, check the pump station, pipeline, and valves.
3. Flow Test
Keep the system operating at the rated working pressure.
Activate the flow meter and record real-time water flow.
Compare with the monitor’s technical specifications (e.g., 30 L/s or 50 L/s).
If flow is too low, check for water supply issues or pipeline blockages.
