Fire Hydrant Gauges Melbourne Testing: Micrometer M1104 in Action
Accurate Fire Hydrant Gauge Testing in Melbourne: Using the Micrometer M1104
During a recent fire hydrant gauges Melbourne testing at a small apartment block, the Micrometer M1104 enabled efficient gauge readings without a Y Piece. This Melbourne testing setup allowed the system’s pumped hydrant to exceed performance expectations, delivering precise readings and ensuring compliance with standard requirements.
Observed Non-Compliances in Melbourne Fire Hydrant Gauge Testing
Although this hydrant system was certified within the last three years, recent testing revealed some non-compliances that are essential to address:
- Missing Gauge Requirement: For systems with more than six hydrants, any installation with a gap exceeding 25 meters requires a gauge installed at the top. This particular installation was missing this critical gauge, which is necessary for accurate pressure monitoring.
- Drain Limitation Issue: Although a drain system was present, its restricted 50mm capacity could limit meter effectiveness, potentially affecting performance where larger drainage is required.
Despite these findings, the hydrant system maintained compliance with operational standards, delivering the necessary flow and pressure levels, with the pump activating as needed.
Melbourne’s AS 2419 – 2005 Standards for Fire Hydrant Gauges
General Pressure Gauge Requirements (AS 2419 – Section 9.3.1)
Under AS 2419 – 2005, fire hydrant pressure gauges in Melbourne installations must:
- Comply with AS 1349 standards,
- Include a gauge cock to allow easy servicing or removal,
- Have a minimum dial face of 65 mm in diameter unless otherwise specified, and
- Feature a window made of durable glass.
Specific Locations for Fire Hydrant Pressure Gauges (AS 2419 – Section 9.3.2)
Melbourne fire hydrant systems should position pressure gauges at:
- The suction and delivery sides of booster pumps,
- Near any fire brigade booster inlets,
- The delivery side of pressure maintenance pumps, and
- Each pressure switch location.
For buildings with:
- Heights up to 25 meters: Gauges should be at the most hydraulically disadvantaged hydrant when more than six hydrants are installed.
- Heights over 25 meters: Each pressure zone should include gauges at the most disadvantaged hydrant and near any pressure-reducing valves.
Strainer Requirement for Fire Hydrant Gauges
When water supply may contain particles that could restrict operation, strainers are essential. These strainers should have a hole size below 12 mm to prevent clogs, ensuring uninterrupted performance.
