The Omni Marker is compatible with all marker locators. Since it utilizes industry standard frequencies, it can be used with any electronic marker locating device, including the Tempo EML100 Electronic Marker Locator.

Identify, Detect & Map Your Networks

A marker tailored to your site's critical requirements - the imperative to enhance safety during works and safeguard buried assets.

Imprecise mapping, legacy uncharted connections, and limited knowledge of underground network locations can result in significant annual damage: environmental contamination, worker health hazards, resident disruptions, flooding, electrocution, and more.

Non-conductive services like plastic pipes are particularly challenging to locate conventionally, but with buried utility markers, you can swiftly and effortlessly resolve these issues.

Global legislation concerning street-works is becoming more stringent. Changes are necessary as network operators strive for:

  • Enhanced worker safety on-site
  • Preservation of buried asset integrity
  • Environmental protection
  • Minimised impact on residents
  • Prevention of project delays
  • Detailed cost management

A Marker for Each Network Type

Potable water, gas, telecommunications, sewerage, electricity, lighting, and more.

Passive markers are indispensable for network asset management. They're interred alongside new networks during deployment or maintenance work.

Utilised for marking networks and their key points (junctions, elbows, depth or direction changes), they've proven uniquely capable of precisely locating and identifying network positions, regardless of soil type (earth, sand, concrete, etc.).

Passive markers can be identified near power supply networks, metal pipes, grids and other passive markers, provided installation conditions are met.

Red for electricity, blue for water, etc. These colour-coded and frequency-specific markers save time, optimise human and material resources, and help prevent costly maintenance errors.

Advanced Marker Technology for Every Application

Passive markers: Precise localisation, over 1.50 m deep.

The Omni Marker II employs a magnetic antenna system for precise utility detection. Its core comprises an inductive coil antenna and capacitance, forming an LC circuit that resonates at specific frequencies. Tempo Communications' markers are passive, drawing energy from the detector's magnetic field without internal power sources.

Crafted from high-density polyethylene, the same material used in most buried plant, these markers boast exceptional durability. They're waterproof, chemical-resistant, and able to withstand temperature fluctuations. Interoperability is ensured through industry-standard frequencies: 145.7 kHz for drinking water, 101.4 kHz for telecoms, and 83 kHz for gas, among others.

Detection occurs via induction, a non-intrusive method allowing location of all pipelines from above ground. This approach enhances survey quality before works commence, reducing confusion and bolstering safety. By strategically placing markers throughout the network and utilising complementary tools like marker detectors, GPS, and GIS databases, networks can be mapped point by point with precise coordinates (X,Y,Z), based on Tempo Communications studies.

The Omni Marker II's self-levelling, large-diameter coil structure ensures pinpoint accuracy.

Easily detectable up to 1.5 m away, the Omni Marker II provides a robust signal that remains locatable for years. Its peak signal directly above the marker allows for precise positioning within centimetres.

No need for level placement during burial. The self-levelling coil assembly means you can 'fit and forget'. Simply attach the marker to the service and backfill; the coil will settle to provide an accurate location directly above.

Compatible with all marker locators, the Omni Marker II uses industry-standard frequencies, working seamlessly with any electronic marker locating device. Ask about the Tempo EML100 MarkerMate™ locator, capable of detecting all markers with its unique 'scan' mode.

The passive, high-reliability design ensures years of service. Containing no batteries or active components, the Omni Marker II is built using the same long-life materials as its predecessor, guaranteeing longevity matching your buried plant.

Lightweight and free from hazardous chemicals, the Omni Marker II eliminates the need for material safety data sheets. Its durable yet lightweight design keeps shipping and storage costs low whilst providing years of dependable service.

 

Applications

Precisely locate non-conductive lines Polyethylene networks are widely used in gas, water, and sanitation systems. However, once deployed, their detection becomes nearly impossible without proper marking.

The Omni Marker II, a cutting-edge buried utility marker, offers installers a reliable solution for pinpointing non-conductive lines. Its advanced technology ensures accurate detection and mapping of underground utilities, enhancing safety and efficiency in excavation and maintenance work.

The same principle applies to modern telecommunication networks, particularly fibre optic systems. Whilst 'as-built' maps may include precise GPS coordinates at installation, they often fail to account for gradual changes. Over decades, tectonic shifts and slow landslips can introduce metres of error. Moreover, field teams rarely have access to high-precision GPS equipment. This is where buried utility markers prove invaluable.

These passive markers facilitate precise location before digging commences. Teams can navigate to the general area using standard GPS and mapping tools, then scan the ground for markers to pinpoint the exact dig site. Resonant markers enable quick, accurate, and positive network identification.

By employing buried utility markers, you enhance employee safety and protect valuable assets. These markers also allow field teams to swiftly verify plans provided by network operators, accurately position within the network, and avoid conflicts with other buried utilities.

During emergency works, markers prove exceptionally useful. They aid in the rapid and straightforward search for all networks to avoid, thus preventing costly maintenance errors.

Locating Notable Network Points

Across various utilities—gas, electricity, telecommunications, district heating, or water—networks typically feature key points that often represent vulnerabilities:

  • Wastewater connections
  • Junction box access chambers
  • Repairs or splices
  • Network crossings
  • Direction and level changes

These notable points are generally challenging, if not impossible, for field teams to spot from the surface. Installing passive markers allows future workers to quickly identify and differentiate these points from the rest of the network.

Cost-Effective Network Mapping: Closed Trench Geo-referencing

Geo-referencing an open trench network requires regular presence of a competent person and specialised equipment, which can quickly become expensive. One solution is closed trench geo-referencing by positioning markers along the network during works.

This approach can be followed up within weeks by a precision survey to complete regulatory compliance and log mapping surveys.

 

Advanced Marker Technology for Easy Installation

Installation Guidelines Place passive markers atop or beside the object to be marked, maintaining consistency, at a maximum depth of 1.5m. Secure them with one or two cable ties or special adhesive clips. Markers can be buried in any orientation, as their peak sensitivity is always directly above. Regarding quantity, the following practices are most common:

Linear Runs

For linear runs, place a marker every 20 metres.

Radial Runs

For a curvature radius less than 1 metre, use 2 markers (most common for connections). For a radius greater than 1 metre, use 3 markers.

Bypass Attachments

If an underground bypass attachment exists, a buried utility marker may be positioned on the network as near as feasible to the attachment. This marker signifies the network connection's starting point.

Omni Marker II: The Superior Location Marker Ball

Engineered for use in narrow trenches from 10 cm wide to 1.50 m deep, this passive electronic marker features a self-levelling coil. The Omni Marker II houses a large-diameter resonant coil structure. When activated by a locator at the standard frequency, these entirely passive circuits generate a precise 'dipole' magnetic field above and below. This allows for accurate positioning, regardless of its placement in the ground, optimising location precision. Lightweight and posing no pollution risk, it's completely passive, contains no fluid, and is built for maximum durability. It's designed to last as long as the underground network and can be reused if unearthed.
