Pulse flow process
The Trotec pulse flow kit includes all you need in a handy case: Pulse transmitter, receiver, measurement probes as well as cables and winders.
- Benefits in practice:
- Simple measurement technology –
easy to operate - Fast leak location
- Tough sturdy technology
The Trotec pulse flow process is ideal for simple leak location in flat roofs. It enables the precise location of leaks on roofs with non-electrically conducting sealants, e.g. Sarnafil membrane or bitumen. It is better if ballast materials such as gravel or turf are left on the sealant.
The process can be used on both hot and cold roofs. The precondition for location is the penetration of moisture through the insulating layer below the sealant layer.
Principle: In the pulse flow process a ring main (minus pole) is created on the surface of the sealant while on the underside the plus pole is created via the earth cable. As the roof membrane is non-conducting the current generated by the pulse generator flows via the damp roof membrane to the leak point. Two measurement probes are used to determine the direction of flow of the current and find the leak point. It is important in this case that the upper sealant layer is sufficiently wetted.
