GET IN TOUCH

Online's range of compact magnetic signallers detect magnetic pigs in any pipeline medium, removing any uncertainty over pig passage allowing operations to continue on schedule. Minimal set up is required ensuring that time is not wasted setting up various parameters

Events are signalled as they occur via a graphical display and high brightness LEDs positioned around the perimeter of the display. The unit logs the time and date of up to 99 events. Logged events can be viewed locally on the display and reviewed at a later date
