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

• DVGW W 405 / W 392: Provision of firefighting water via the drinking-water network (planning / fundamentals) and test intervals
• DVGW W 405-B1: Draw-off by the fire brigade incl. requirements for drinking-water protection (system separator / backflow prevention)
• DIN EN 14384 / DIN EN 14339: Product standards for pillar and underground hydrants (requirements / tests)
• DIN 14462: Planning, operation and inspection of non-public firefighting water systems (e.g. in buildings) | annual testing and documentation requirement

Note: The device is intended for measurement and documentation; evaluation is based on the above standards and/or local utility requirements.
