The CWA leak detection system locates leaks with exceptional precision

  • Works with all types of sprayed or injected pre-insulated pipes, including HDPE and steel.

  • Alarm wires can be installed on the surface of the pipes using double-sided tape

  • Can be used for all liquids with a dielectric constant above 3.0

  • Works as a stand-alone unit or can be connected to a BMS via LAN

  • Each unit monitors up to 8 000 m / 24 000 ft of sensor wire

  • Up to 250 units can be linked together

  • Leaks are located within +/- 1% of the distance

  • Type of fault, distance, time and date recorded and stored

  • Easy to install, to operate and is maintenance free

  • Dimensions: 330x270x200 mm

  • CE-certified

Scalable system

The field of application is extremely wide; from small district heating/cooling projects to projects covering several hundred kilometres.

Various industries

CWA customers operate in a wide range of industries; from pipe manufacturers and industrial companies to nuclear power.

All climates

Thousands of systems are installed worldwide. The system is just as reliable to operate in arctic climates as in the desert or in urban centres.

The CWA leak detection system is developed and produced in Sweden since 1981

  • Alarm units

    Alarm units are installed at suitable places along the pipes together with matching boxes, LAN and battery backup equipment.

  • Sensor wires and cables

    Alarm wires are installed in the isolation. The wires are connected to each other by crimping and soldering in the fieldjoints.

  • Host computer

    The host computer monitors the alarm units, carry out communication, store data, presents status data and other information.

  • Communication cable

    The Host Computer and the alarm units communicate by a 4-wire communication cable system.

  • LAN

    At each alarm unit location, a LAN connection can be installed to handle communication.

The CWA leak detection system works with all kinds of pre-insulated pipes

The most common liquid is water but applications goes for beyond, for example, ethanol, ethylene glycol, and propylene carbonate.
