tele-RANGER Telemetry System


The locally developed tele-RANGER Telemetry System has shown exceptional performance and adaptability, resulting in the capture of a major share of the Southern African telemetry market. Its field proven, user-friendly modular design has made it the ideal product for the harsh African environment.

tele-RANGER finds application in most walks of life as the technology is employed for purposes of water reticulation, sewage reticulation, electrical reticulation and traffic control. It is also used by water management institutions.

A Central Station can be computer-based with modern powerful SCADA software for sophisticated control and data processing, or Mimic Panel display.

Communications options include Radio (conventional or trunked), Landline, Microwave, Fibre optic and PSTN.
