Non-return flange type (side mount)

Stop valve type (side mount)   

Immersion type (top mount) 

Rotate the displayer table cover counterclockwise, remove the cover and the glass panel, and screw the zero adjusting screw with a slot type screwdriver until the pointer points to the critical value of zero point. Then reinstall the glass panel and the displayer table cover. (Remarks: The critical value means that the pointer is close to the stop pin but applies no force to the stop pin.)

Close the isolating valve which connects to the level gauge sensor and loosen the bolt between the level gauge sensor and the isolating valve to completely drain of the liquid inside the sensor cavity. Then operate in accordance to the procedures under no liquid condition.

Rotate the displayer table cover counterclockwise, remove the cover and the glass panel, and screw the zero adjusting screw with a slot screwdriver until the pointer points to the actual level. Then reinstall the glass panel and the displayer table cover.
