Liquid Flow Controller LC Series
Application conditions
1.1 Uses and features
The liquid flow controller has a liquid flow measurement function and can accept the computer to set the flow value and adjust it by PID.
Control the regulating valve to automatically complete the flow adjustment. Flow controller has small size, high integration, high accuracy, and adjustment time small,
easy to use, stable work, etc., according to different media, need to have explosion-proof function.
The liquid mass flow controller is capable of collecting liquid flow from the pipeline and is capable of accepting computer settings via PID The program controls the
regulating valve to complete the automatic adjustment of the flow.
The flow controller has small volume, high integration and high accuracy.The adjustment time is small, the use is convenient, and the work is stable.

Picture(4)Installation diagram of double ferrule splice
As shown in picture 4, when installing the splice, after installing the front ferrule, back ferrule, and nut, tighten the nut and the splice by hand, then tighten with
a wrench (The imported Swagelok splice requires a 1.25-turn wrench to tighten.) to ensure air tightness. Note that double wrench should be used, with one
wrench stuck in the joint and the other to turn the nut. Especially when removing the nozzle, double wrench must be used, otherwise it will cause loosening
of the joint and affect the sealing.
