Abstract (en)
[origin: WO2017093655A1] Misting device (1) having piezoelectric excitation, comprising: - a liquid tank (10), - a piezoelectric element (40) having an active surface (41) capable of transmitting acoustic waves in the liquid for misting said liquid, said device being characterised in that it further comprises: - measurement - means capable of measuring a parameter representative of the current consumed by the piezoelectric element, - alert means, capable of being activated by the control means when the instantaneous value of said representative parameter lies outside a predefined range.
