This switch is a single pole double throw(SPDT) flow switch, used to detect and observe the liquid flow rater relay, normally for air adjustment and application in the field of water supply equipment. It is usedt to sense the change of the flow rate of the liquid, such as water, ethylene, glycol or other non-hazardous liquid passing through the pipeline, with the typical application as loacations where the interlocking effiect or: Flow breaking protection is necessary.
