The extinguishing water rate of installed hydrants is required for regulatory planning permission, as well as ground and property protection plan for the fire brigades.
The required extinguishing water rate per hydrant is defined at 800 l/min.
The exact determination of the extinguishing water rate is only measurable/possible locally on-site.
The measurement data is recorded by means of an electronic testing device and then evaluated on the computer.
In case of increased performance requirements (industrial area), 2 hydrants can be tested simultaneously.
Measurements at the ends of stub lines, at low line pressure and at objects with increased fire load (operational area) are important.
