2. Bi-directional Feather
3. Uni-directional
Three indicator types are available:
1. B_Manual reset flag
2. C_Manual reset flag combined with electrical switch output
3. D_Digital display combined with electrical switch output
Three mounting types:
1. 2″flange connection
2. 2″welded nipple

Features of EMT Pig Signallers
l Suitable for pipe sizes from 2” upwards
l A range of design pressure from ANSI 150 # to ANSI 2500 # are available for 2 "flange connection,
The highest design pressure is 10000Psi(69MPa) for boss connection.
l The working temperature range is -20ºC to +120ºC. Special seals can be provided for operating temperatures outside this range
l Trigger mechanism does not use dynamic seals therefore both prevent leakage and ensure trigger flexibility(The boss connection, with pop-up indicator or the digital display is excluded). The flag is interactivity with the trigger mechanism, therefore, the flexibility of trigger mechanism can be checked online.
l The requirement about adjusting Insert depth can also be met.
l Easy to operate, Proven durability, minimal maintenance required.
Suitable for all types of pipeline pigs such as Foam Pig, metal Bodied Pigs, Spheres, Intelligent Detection Pig
