Hinni AG: Leak detection

THE PERMANENT WATER PIPE MONITORING SYSTEM

LORNO is a smart leak detection system which automatically sends events from the drinking water network to the server through radio data transmission (7x24 push system). The user is informed via either E-mail or SMS.

How does the leak detection work? What role does the raw material play?

THE HYDROPHON – DIRECTLY FROM THE TAIL-WATER TECHNOLOGY

The hydrophone, also known as the underwater microphone, receives the water sound waves, transforms them into measuring signals and transmits them to the electronic unit.

LORNO uses this technology to detect leaks through acoustic changes.

LORNO registers acoustic reference measurements and reports variations from the reference measurement through E-Mail or SMS (7x24 push system).

Integration Possibilities

Above ground hydrants
Underground hydrant
Directly into the main pipe (LORNO-T)

Measurements

After an initial reference measurement, individual reference values (frequency and amplitude) are stored in the measuring modules.

The hydrophone proceeds to track the noise measurements automatically at intervals and compares the measurements with the reference measurement.

THE PIPE MATERIAL

For LORNO, it is not significant if the pipe is made of. cast iron, polyethylene or another material!

PE pipes act like filters and can be a great challenge in case of leak detection.

Leak detection systems that transmit noises through impact sound (e.g. Logger based systems) cannot be used for PE pipes.

Thanks to the hydrophone being directly inserted in the pipe for the LORNO leak detection, the acoustic sound can also be transmitted into the PE pipes through water.

Therefore, LORNO is the only leak detection system that can be inserted in all types of pipe systems whether the pipe networks are made out of cast iron, PE or mixed pipe materials!
