The ICT Water Level Meter (WLM) is a rugged, self-contained, standalone logger designed to collect and transform data from SDI-12 sensors, the WLM is able to receive up to 255 parameters from a maximum of 62 individual sensors via Combined Instrument Software (CIS). Designed to allow easy access to the collected data, the WLM Logger stores data on an internal MicroSD card for retrieval either using the USB port, 2.4GHz wireless network, or when combined with the ICT International Telemetry hub via the mobile phone or Iridium satellite networks.
Configuring the WLM using CIS, the user has the ability to enter a reference water level, thereby allowing logged levels to be referenced to local or national datum points for surface water monitoring, or depth to water for groundwater monitoring.
The WLM converts recorded level into flow rates or volumes based on user defined parameters:

The WLM can be factory optioned to support analogue and 4 – 20mA sensors.
