Datasheet
Portable measuring device for rapid performance testing of above-ground and underground fire hydrants. It determines and documents static pressure, flow pressure and flow rate directly at the draw-off point – ideal for fire brigades, network operators, water utilities, municipalities and service providers.
- Annual inspection of hydrants to ensure operability as a firefighting water source and compliance with fire-protection regulations
- Fast on-site measurement with clear key figures (static/flow pressure, flow rate)
- Documentation-ready for performance and condition records
- Rugged design for field use
- Compatible with pillar and underground hydrants; common connectors, e.g. Storz-B
- Optional: integration of a system separator/backflow preventer in accordance with DVGW practice
- Carrying handles and fold-out feet

Measured variables
- Static pressure: line pressure without draw-off
- Flow pressure: pressure during draw-off
- Flow rate (l/min): delivery rate of the hydrant at a defined pressure
- Minimum residual pressure: verification value for assessing network security
Standards & practical reference
