Paper discusses a novel version of fluidic sensors based upon two wall-jets colliding head-on, both attached by the Coanda effect to the same cylindrical surface. The sensors may be particularly suitable for operation at low Reynolds numbers. Performed experimental investigation combined with numerical flowfield computations revealed symmetry breaking which leads to existence of three alternative different stable flow regimes. This opens a possibility of designing fluidic tristable amplifiers and control systems operating with ternary logic.
