FIELD: automation of manufacturing processes, applicable for automatic measurement of foam layer thickness and pulp level in flotation machine chambers at concentrating mills of extractive industry. SUBSTANCE: the device in addition has a generator, shaper, ring counter, electronic switch unit, the first, second and third, RS-flip-flops, the first and second AND gates, resistance box connected to the unit of electrodes insulated from one another, located along the vertical in the flotation machine chamber, the first and second electric decoupling devices, the first and second filters, the first and second voltage-to-current converters, whose outputs serve as outputs of the entire device. EFFECT: enhanced reliability of registration of parameters of the flotation process, absence of kinematic assemblies in the device, reduced cost of the device. 1 dwg
