LK01ALiquid Flow Switch is used in the circumstance where chain effect or cut-off protection is needed. It is to supervise the liquid flow rate through the pipes. When liquid inside the pipe circulates or cuts off, flow switch will correspondingly alters the ON/OFF state so as to control and protect external devices. Liquid Flow Switch is suitable for any liquid medium that makes no corruption on brass and tin-bronze and takes no effect on air-proof performance.
CHARACTERISTICS
l Suitable for pipes from 3/4" to 8"
l Applicable to cool/heat water system
l Strong die-casting aluminum alloyed casing and cover
l R1 or R3/4 male thread joint; Easy mounting
l Dependable and durable parts such as forged brass, tin bronze, stainless-steel and high-strength flameproof engineering plastic
l Complete airproof design
INSTALLATION
l Mount on return pipes
l Mount on horizontal pipes
l Keep a certain distance from sources of turbulences (Elbows, valves, pumps, etc) so as to ensure steady working flow. Recommended minimum distance is equal to 5 times of the pipe's diameter
ADJUSTMENT OF FLOW RATE SETTING
Flow setting device is combined by adjusting screw and spring. Fully tighten the screw to obtain minimum flow rate setting, fully loosen the screw to have maximum flow rate setting. The following table gives the values for limiting flow rate settings in relation to the pipe diameter and blade length. The LK01Ais supplied ex-factory with the setting screw fully tightened (minimum setting).
