Station with high-capacity batteries

STELA – Telemetry Station, GSM/GPRS Data Logger

Telemetry Stations - Thanks to its high mechanical durability and very long operating time without needing to replace the power batteries, the 3rd-generation STELA GSM/GPRS data logger is suitable for measurements in locations where it is not possible to connect the measuring station - the data logger to an external power source.

  • Operating life of up to 10 years without battery replacement
  • Pulse inputs for REED and OPTO flow sensors
  • Current inputs for pressure and level sensors
  • RS485 interface for connecting multiple external sensors
  • GSM/GPRS module for regular data transmission to an Internet server (telemetry station)
  • Integrated system for warning and informational SMS messages
  • Very low operating costs
  • Modern electronics design, energy-efficient RISC microprocessor, comprehensive software suite
  • Robust metal housing with high protection rating
  • Low price

Description

The telemetry station meets the high requirements for battery-powered devices primarily thanks to its unique design, which—in addition to its own electronics with very low current consumption—includes 2 to 4 lithium batteries with a maximum capacity of more than 50 Ah. These batteries also have very low self-discharge rates and are therefore capable of powering the telemetry station—along with its connected sensors—for more than 10 years while transmitting measured data daily to a database on a server via a built-in GSM/GPRS modem.
STELA-3 telemetry stations can thus be used to create extensive monitoring networks independent of an external power supply, and they can also be combined into a single system with the more sophisticated H7, H3, or with the small H1 and H40 data loggers.

Applications

  • Monitoring of instantaneous and minimum nighttime flow rates, including flow balances, and remote water meter readings
  • Continuous monitoring of flow rates, pressures, and water levels in measuring wells or reservoirs
  • Groundwater level monitoring
  • Construction of a network of rain gauge and limnigraph stations
  • Monitoring of industrial processes or facility security
  • The compact design allows the station to be installed even in very small spaces, thereby better protecting it from vandalism
  • Measurements in underground sections of sewer networks, transfer chambers, water reservoirs, and other locations without an external power source
