Introduction and Features
MicroCorr
®
DIGITAL is the latest model of the world’s leading correlator brand (over 4,000
MicroCorr
®
units in use worldwide) but is the first fully digital system. This enables it to
achieve performance levels well in excess of previous analogue-based systems, with
important benefits to the user.
• Totally digital system
• Superior leak detection performance on all pipe materials and sizes
• Quick and easy to use, especially for less experienced operators
• Automatic parametric filtering (APF)
• Ergonomically designed – lightweight, compact system
• 1/4 VGA colour display
• Software upgrades via Internet web site
• Optional third Out Station for velocity measurement and rapid survey
• Select dedicated or PC-based models
New features
• Transceiver communication enables all system functions to be controlled centrally,
enabling quicker deployment
• Expert system leak detection algorithms eliminate transient, non-leak effects
• Tricorrelation (optional third Out Station/sensor) automatically calculates site-
specific velocity
• Data replay function allows immediate post-processing or off-line correlation
• Software upgrades downloaded directly from www.palmer.co.uk
• Results transferable into Windows PC for post-processing or export
Best in the field
Leak detection staff require a high performance correlator in order to maximise their
productivity (number of leaks found per hour) and minimise the incidence of “dry” holes, when
excavation reveals no leak to be present. However, because it is used constantly in the field,
the correlator must also be robustly designed.
The Control Unit and Out Station are injection-moulded housings, providing maximum
strength and durability. They are designed to IP65 protection and to survive a 1 metre drop.
The Control Unit incorporates an external antenna and a magmount antenna (optional extra)
may be connected for longer correlation distances if the Control Unit is vehicle-based.
External antennae are used with the Out Stations.
All connectors are military specification and cables are fitted with strain relief to protect
against fatigue damage. The complete system, comprising control unit with two Out Stations
and sensors, is easily carried by one person. The Out Stations have been designed to be
visible over typical correlation distances and allow back-to-back portability.
