The primary mode of transmission for Legionnaires’ disease is through inhaling aerosols - tiny water droplets contaminated with the bacteria.
The disease doesn’t discriminate, but some are more susceptible than others. Individuals with chronic lung disease, those residing in hospitals and nursing homes, and smokers are particularly at risk. Untreated Legionnaires’ disease can lead to severe complications, especially for those with a weakened immune system.
In France, the prevention of Legionnaires' disease is governed by strict regulations that vary depending on the type of installation. Specific requirements apply to healthcare facilities, public-access buildings, misting systems, and cooling towers. These include monitoring procedures, water treatment protocols, and regular maintenance.

An ultrasonic flowmeter works by transmitting a sound pulse from the sensor to the water flow and measuring the return time of the echo, whichcorresponds to the distance between the sensor and the water surface. This enables it to measure the level in a channel.
For most ultrasonic flowmeters, the minimum straight pipe required is usually 10 to 15 inches (or 25 to 38 cm) in diameter. For example, a 4" (10 cm) diameter pipe requires 40" (100 cm) of straight pipe. Bear in mind that larger flow distortions may require additional straight pipe.
The accuracy of ultrasonic flowmeters is quite high, with a typical accuracy of between 0.5% and 1%. They are therefore considered reliable for accurate measurements.
Legionnaires' disease is not easy to catch, as most people exposed to the bacteria do not develop the disease. The bacterium is generally found in water sources such as cooling towers, showers and jacuzzis.
