working principle:
The WF-16 blade type flow switch uses the flow force of water to drive the blade to test whether the liquid in the pipe flows. When the liquid does not flow in the pipe, the spring pushes the magnet down to the blade to be vertical, and the reed switch does not move. The contact is in the normally open (NO) position. When there is liquid flowing in the pipe and the liquid flow is sufficient to push the blade 20--30° higher, the eccentric drive piece above the blade pushes the magnet upward, and the suction of the magnet makes the magnetic The reed switch operates and the contacts are turned on. The length of the blade varies with the diameter of the pipe.
Features:
Good repeatability; low pressure loss; good dirt resistance, good dust and water resistance
WF-16 explosion-proof water flow switch is a new structure of explosion-proof block flow switch. It is manufactured in strict accordance with the explosion-proof process. It is greatly simplified in structure, reliability, service life, operating temperature range, working pressure and working environment. The requirements are much better than ordinary target flow switches.
