Dölco FD 3 Flat Roof Leak Locator - Electro-Acoustic Detection System

Dölco FD 3 is an advanced, electro-acoustic system for locating leaks on flat roofs, designed to work on bituminous roofing, PVC foil, green and gravel roofs - without the need to expose the top layers. The technology enables precise leak detection with centimeter accuracy, even in difficult weather conditions and safe for the operator.

🔍 Application:

• Leak location on flat roofs with felt or foil

• Diagnosis of leaks under gravel, vegetation, and finishing layers

• Detection in ventilated and non-ventilated roofs

• Leakage tests in humid and rainy conditions - no risk to the user

✅ Advantages of the FD 3 system:

• Operates on alternating current (AC) - faster response and higher detection sensitivity

• No need to remove topcoats

• No ring circuit required

• Operation in all weather conditions - even in rain

• Safe 5V voltage - no shock hazard

• Visual and acoustic leak alarm

• Optional battery - greater mobility and autonomy in the field

🎧 How it works:

The FD 3 system locates leaks by analyzing changes in electrical conductivity on a damp roof. After the generator sends a signal and wetting the surface, the operator uses a scanning rod and headphones to precisely locate the leak point, which is indicated by a change in tone and an analog reading on the meter.
