In an apparatus for treating liquid with electromagnetic flux, coils (L1, L2 and L3) surround a pipe (16) and are excited by a switching circuit (72) that includes a triode switch turned on and off in response to the voltage applied to the coil (L1, L2 and L3) such that during operative half cycles current is conducted through the coils (L1, L2 and L3) initially, and then substantially before the end of each half cycle, the circuit causes an open condition during which current builds up in the coils (L1, L2 and L3). This produces a ringing current in and ringing voltage across each coil (L1, L2 and L3) and consequent ringing electromagnetic flux in the liquid passing through the pipe (16). Preferably, the fluxes produced by at least two of the coils (L1, L2 and L3) move in opposite directions through the pipe (16).
L'invention concerne un appareil de traitement d'un liquide présentant un flux électromagnétique et des bobines (L1, L2 et L3) entourant un tuyau (16) et qui sont excités par un circuit de commutation (72) comprenant un commutateur triode mis en route et arrêté selon la tension appliquée sur les bobines (L1, L2, L3) de manière que, pendant les demi-cycles opérationnels, le courant soit d'abord conduit à travers les bobines (L1, L2, L3) et que, sensiblement avant la fin de chaque demi-cycle, le circuit soit ouvert, période pendant laquelle le courant se forme dans les bobines (l1, L2, L3). On obtient ainsi un courant d'appel et une tension d'appel traversant chaque bobine (L1, L2, L3) et ultérieurement un flux électromagnétique dans le liquide traversant le tuyau (16). Les flux produits par au moins deux des bobines (L1, L2, L3) se déplacent, de préférence, en sens inverses à travers le tuyau (16).
