Embodiment Construction
[0031] refer to figure 1 , a clogging detection device D can be seen, which detects clogging of a mechanical fluid meter 1 , more particularly a water meter, mounted on a pipe 2 . The meter 1 comprises an upstream connection 1a and a downstream connection 1b according to figure 1 , the fluid flows in the direction of arrow F from left to right.
[0032] The device D comprises measuring means M which measure the temperature difference between the temperature of the fluid in the vicinity of the meter 1 and the temperature of the environment in which the meter is located. The measuring means M comprise a temperature sensor 3 of the temperature of the fluid in the vicinity of the gauge 1 . Preferably, the sensor 3 is located immediately downstream or upstream of the meter 1, for example on the connection 1b, or the sensor 3 is located in the body of the meter itself. A further temperature sensor 4 is provided for acquiring the temperature of the environment in the vicinity of t...
