600 Series Acoustic Pingers

Make significant savings in vessel time with Online's versatile acoustic pig locators

Online’s 600 series acoustic pingers enable quick and accurate locating of a stalled pig in a liquid line leading to significant savings in vessel time and therefore costs.

The pingers are highly configurable and can be custom-made with different ping rates and frequencies as per the client’s specifications. This allows for differentiation between pigs within a pig train and can also be used to extend the battery life.

The 600 series pingers are activated once immersed in fluid; thus allowing them to be loaded months in advance of the flooding operation. The pingers are capable of sending acoustic transmissions over distances of several kilometres, dependent upon unit configuration, mounting arrangement and environmental conditions.
