Locating pipelines with the stopper
The stopper is an optional accessory for the
COMBIPHON
sys-
tem. The stopper is designed for use on water mains.
The stopper can be connected to:
●
DIN above-ground hydrants
●
DIN underground hydrants in conjunction with a standpipe

Functional principle
When water is withdrawn from a hydrant, the water column is set
in motion. The stopper slows down the water column at intervals.
This generates noises that travel along the line and can be locat-
ed even at long distances.
For the location process itself, an appropriate system for acoustic
water leak detection must be used (e.g.
AQUAPHON
system).
