Ultrasonic flow device for accelerating chemical maturing proceeses in liquid eubatancoe
being treated with u1traeonic8:
Ultrar~onios outputs 300 to X00 watts
Rate of flow of liquid: 30 to 200 liters per hour
The flow vessel is dimensioned depending on the vtsco$ity and the sound absorption of
the substance being treated, while the ultrasonios oscillator and the CIF generator a1way
are of the same dimensions.
All elements of the ow verse],, such as stopcoe, eorew threads, piping, etc. are
