This unit is the corollary equipment of mobile and partial foam extinguishing system that fits high, middle and low expansion foam extinguishing system. This series foam proportioner can divided into flange and buckled according to connecting way.
The principle of the in-line inductor is that the pressurized water will flow through a narrow part when it flows into the proportioner (in-line inductor). There will be a narrow part in the pipeline and a branch pipe was connected with foam tank there. For the flow velocity at the narrow place gets bigger than other places that its pressure gets smaller, resulting in vacuum at the outlet. Thus the foam concentrate was absorbed to foam generator and mixed with pressurized water.
