working principle:
Baffle flow switch is used to detect air, oil and water flowing in one or two directions, and there should be no entanglement in the medium. When the fluid flows through the pipeline, the baffle deflects, and the single-pole double-throw micro-switch acts on the set flow rate by adjusting the adjusting bolt, and outputs a switch signal; when the two-way detection, the baffle offset pushes the magnetic module to move up, and the switch is driven. Module action. It is used to detect air and water flowing in one direction, and there should be no entanglement in the water. When the fluid flows through the pipeline in the indicated direction, the baffle deflects, and by adjusting the adjustment bolt, the single-pole double-throw micro-switch is operated on the set flow rate to output a switch signal. It has a wide flow range and convenient adjustment for wide-area measurement of water, gas and oil.
