Flag Type Passage Indicator

Passage Indicator Technical characteristics:

1、 Design Pressure:10Mpa (Special requirements shall be separately designed).

2、 Applicable Temperature: -20-100℃.

3、 Installed pipeline diameter≥89mm.

4、 Medium: oil, water, gas and other non corrosive fluids.

5、 Pipeline material: 

A: Steel welding performance is good for all kinds of metal 

B：Special environmental required stainless steel material.

6、 The length of the trigger into the pipe≥25mm.

7、  Pigs pass within the pipeline  by two directions  , this indicator can be displayed。

8、 Suitable for explosion-proof site installed.

9、Flag (label ) indicator adopts mechanical transmission mechanism, swing trigger > 45 degree Angle, the label by the transverse(arrow cross) into longitudinal (arrows up), shows that the pig has passed, and remote transmission of a 24 VDC, 3A guide communication。

10、Remote control signal duration：5S.

11、Remote interface 1/2NPT or 4NPT.

12、To facilitate observation, maybe special process a elongated ball indicator.

13、Can be achieved remove functions with pressure.

Passage Indicator Use and Maintain:

1、remove protecting cap before  passed the ball , display mechanism will be (flag type display mechanism) installed on the mechanical body, and tighten locking screw, display mechanism can rotate 360 degrees, easy to adjust the observation direction。

2、Counterclockwise press label

3、When pig passed, label up, and remote transmission of a node guide communication.

4、When repeat the pigging, repeat 1 ~ 2 processes。

5、After pigging ball-passing, remove under the display mechanism (long-term place) and the mechanical body oil and maintenance, installed protecting cap in order to preventing dust and impurities entrance.
