Trident EM transmitters are reliable, powerful, easy to use, and give the user the option of recording valuable pipeline data during pig runs.

By collecting sensor data while pigging, important insights can be made about the pipeline asset and about the performance of tools, at virtually no additional cost over more traditional pig tracking systems. All transmitters are Bluetooth programmable for frequency (default 22 Hz), power, and pulsing mode. Data can be viewed easily with a free version of PigView-Analytics software.
