Learn how ThingsLog remote water level monitoring works

Operating on NB-IoT or legacy 2G/4G cellular network, ThingsLog LMDL is a remote water tank level monitoring data logger that provides precise configurable metering and fast real-time transmission.

ThingsLog remote level monitoring system design focuses on providing high-quality water level data to its users, with high accuracy and easy to use device kit in a low power way. That makes it extremely suitable for level monitoring on remote locations without an existing power supply.

How to order?

There are several orderable options:

  • Complete solution (logger, sensor, platform and mobile app with included 2G data)
  • Complete solution (logger, sensor, platform and mobile app with NB-IoT
  • Hardware only NB-IoT Data logger with level sensor with MQTT data transfer support

Prior to ordering please check your tank level and the location where the data logger will have to be installed. You need to specify the level depth and the excessive cable length (distance between the top of the tank or reservoir and the location where the logger will be installed).
