Online Electronics’ versatile modular ROV pinger receiver system is a pipeline pig monitoring system used for tracking and locating underwater acoustic pingers

The system comprises - 2001RS Topside Receiver, 2401 Subsea ROV directional Hydrophone & 2402RS Subsea Interface. The 2401 can be mounted on the skid or held in the manipulator of the ROV with the 2402RS mounted on the skid.

Key Benefits

• Capable of detecting acoustic transmissions over distances of several kilometres
• Directional hydrophone provides increased precision
• The received signal can be relayed back to the surface via RS232 allowing it to be interpreted topside
• Parameters such as sensitivity and frequency can be manipulated topside, giving the operator full control
• Minimal set up required ensuring time is not lost setting up multiple parameters
