Passive Utility Markers for Permanent Identification

Choose between Smart (RFID) and standard EMS markers. Ball and disk designs permanently mark joints, tees, bends and crossings—so assets can be rediscovered quickly and unambiguously in the field.

  • Smart RFID markers with unique ID for positive identification
  • Standard (analog) EMS markers for long-term corridor marking
  • Ball (Omni/MAR 3D) and disk types (MiM/Marker 2500/Long)
  • Utility-specific frequencies (e.g., Gas 83.0 kHz; Tel 101.4 kHz; Sewer 121.6 kHz; Power 134.0 kHz; Water 145.7 kHz; Fiber 92.0 kHz)
  • Typical locating depths up to ~1.5 m; deep variants up to ~2.5 m

Smart vs. Standard

Smart (RFID) markers: passive tags with a unique ID—ideal for strategic points and dense installations.
Standard EMS markers: passive, maintenance-free—robust, long-life marking of buried utilities.

Form factors & use

  • Ball markers (Omni/MAR 3D): self-orienting for reliable point marking.
  • Disk markers (MiM/Marker 2500/Long): low-profile; versions for standard (~1.5 m) and deeper (~2.5 m) cover.

Installation tips

  • Place the marker directly above the feature; observe form-factor orientation.
  • Straight runs: on average every 20 m place one marker.
  • Curves/branches: set 2–4 markers depending on bend radius.

FAQ

What does EMS mean?
Electronic Marker System—a passive system with utility-specific frequencies.
How do Smart and Standard differ?
Smart markers carry a unique RFID ID; standard markers are analog without ID.
Which frequency should I choose?
Match the utility (e.g., Gas 83.0 kHz; Tel 101.4 kHz; Sewer 121.6 kHz; Power 134.0 kHz; Water 145.7 kHz; Fiber 92.0 kHz).
How deep can markers be located?
Typically up to ~1.5 m; deep variants (Long/2500) up to ~2.5 m depending on conditions.

Actual range depends on marker size, soil conditions and the receiver used.
