TECMES Hydrometeorological Measurement and Control Networks conformed by Terminal Remote Units (TRU), programmable either locally or remotely from the central station, composed a integral system for acquisition, control, transmission, storing and data processing in real time. These systems designed to operate with hundreds of Remote Units are administered from a Central or Supervisory Station with database and direct communication capabilities with mathematical model for forecast and administration, automatic web pages creation, etc. These networks use communication systems adequate to the user´s necessities, with the following options via satellite: ORBCOMM, INMERSAT, GOES, ARGOS etc; cellular phone, radio Trunking, radio modems in VHF, UHF and Spread Spectrum. TECMES designs, provides, installs and sets up these systems with a high integration degree, taking into account all the variables from the field and the equipment's design.
