Leak Detection

LORNO is the solution to detect leaks early, prevent structural damage and offer targeted support for the security of the water network. Its unique technology allows a simple and quick detection of the presence of water thanks to a sensor on a 1.5 m long wire.

In the context of pornography:

lorno is a type of p-rn that is light and contains a lot of moaning and movement of hands with requisite writhing. It’s the sort of p-rn that you can watch with your mother and is the reason why I hate the Red Shoes Diary so much. It makes me want to get out my lorno and make a huge mess! The system can be used with cast iron or PE pipe systems. It is the only leak detection system that can also be inserted into PE pipes.

Acoustic Measurement

The measurement of acoustic characteristics is an essential component in the development of new materials and products for a wide range of applications. Acoustic measurements can be used to evaluate a material’s sound insulation, reverberation time, level difference between rooms, floor impact sound and sound absorption. Typical acoustic measurement techniques include swept sine sweep and free field methods.

Swept sine sweep methods rely on the acoustic wave pressure measured by a single sensor to produce an impulse response curve that correlates with the sample’s acoustic impedance. This method is limited by the accuracy of the transducer, environmental conditions and signal processing involved in the measurement. Ideally, multiple measurement runs are performed to ensure that the results meet the cleanliness criterion.

Another technique is the oblique incidence method that combines a point source and two traversing receivers to measure the magnitude and phase of the reflection coefficient (Z r c) for a given oblique angle of incidence. This method can be adapted to different oblique angles of incidence and enables the acoustic impedance of the test sample to be determined at discrete spatial locations.

The oblique incidence method is typically implemented in an acoustic impedance tube, but other measurement techniques also have been developed that do not require the use of such devices. For example, the Microflown acoustic sensor directly measures the velocity of an acoustic wave rather than its pressure by measuring the temperature difference between two thin, resistive wires that are a few millimeters apart. The resulting impulse response curves can be used to determine the acoustic impedance without the need for an acoustic impedance device.

The Microflown has been used to test the acoustic properties of Lorno limestone and found to be suitable for a variety of applications, including acoustic insulation and rock vibration monitoring. In the future, it could be adapted for other applications in which sound impedance is important, such as evaluating rock strength and stiffness or determining acoustic attenuation. The acoustic impedance of a material is a complex function that depends on the frequency, the incident and reflected wave angles, the oblique incidence angle, the direction of travel of the waves and the material thickness and mass.


A hydrophone, which is also referred to as an underwater microphone, is a device that receives the water sound waves and transforms them into measuring signals. It is used to detect leaks in the drinking water network. A hydrant with a Lorno system can send a message via radio to the electronic unit whenever a change in the drinking water level is detected, such as when a leak occurs. The signal is then sent to the water authority and the user via E-Mail or SMS (7×24 push system).

Lorno systems are installed in more than 150 points of access provided by water supply companies throughout Switzerland. They enable the detection of leaks and evasions and, thanks to an automatic correlation between hydrants, they significantly limit the spread of the leaking water. This saves the valuable water reserves, prevents the loss of hydrant capacities and reduces the costs of water management.

The smart Lorno technology is based on the WiseNet wireless network, which was developed by CSEM and is operated by Hinni SA. The technology enables the numerous capteurs to be relied on without cables and gives access to the application for managing the network.

In Europe and throughout the world, losses of water in the distribution network due to evasions are considerable. A typical figure is 10 to 30% for our continent. The Lorno system, developed jointly by Hinni SA, CSEM and the Haute ecole specialisée de Lucerne, helps to minimise these losses by making it possible to automatically detect a leak and quickly localise it, thus saving water and preventing damage to the surrounding infrastructures. It does so using a combination of sensors and the intelligent software incorporated in each hydrant.

Its also allows the service of the water company to monitor the quality of the incoming water and the distribution networks. It can also be used to measure the pressure of the supply pipe, and even the temperature of the drinking water. Moreover, it can be used to optimise the use of the hydrants and water meters. It also provides a means of protecting the water supply against contamination by illegal sources and of controlling the amount of water consumed.

Electronic Unit

A computerized unit that converts electrical energy into magnetic energy, and then back again to electricity. It is used to power a magnet’s control system.

The electronic unit in the Lorno consists of a processor, two magnetic circuits and one display screen. It can handle up to four channels of data at once. The processor can also perform calculations and control processes. It can also read magnetic field strength, temperature and current.

(colloquial) Something stupid, annoying or tedious. Teaching 30 children a foreign language is porno to me.

Also, [t] a movie or other work intended to arouse sexual interest. The academic journal Porn Studies is the first peer-reviewed publication dedicated to this subject. It was founded in 2014. The verb to porno is derived from the noun pornography.
