CWA 9000


Automatic Leak Detection & Location System for district-heating/cooling networks, chemicals etc.

The CWA9000 is the result of 35 years of experience including extensive and fundamental research and development.

The CWA9000 is an automatic leak detection/location system. Working on our CWA Pulse Echometry, or TDR (Time Domain Reflectometry), principle, it can be described as a radar. It creates a longitude "map" of the pipeline network, sending defined pulses on the detector wire or cable. Any break, leak or other type of fault, is immediately detected by the alarm unit, stored in a battery-backed memory, and automatically displayed in clear wording. If the unit is connected to a main computer, all information will be transmitted to and stored there. The communication can be carried over telephone lines,

a separate communication cable or via radio link, GSM or satellite. The information can be inspected on a LCD display showing the distance to the fault in meters or feet, time and type of fault.

The CWA9000 has a variety of units and factory installed options together with a wide range of accessories. The units can be configured in different ways depending on the application, type of liquid, environment, power supply or way to communicate. There is a wide selection of detectors and cables available depending on application and climate conditions.

Specially designed cables can be manufactured upon request. Each unit is capable of monitoring up to 4,000 m of pipe, and the system can be expanded to 250 units giving a total capacity of 1,000 kilometres.
