LeveLine-Mini as part of the LeveLine-EWS  Package

The LeveLine-Mini is the level sensor used in the Early Warning System to alert for rising water levels. the clever AquaTelemetry system features a built in pressure sensor meaning the level data recorded by the system is fully compensated for changes in barometric air pressure.

Connect to any SDI-12 datalogger or telemetry device

The LeveLine-Mini has SDI-12 and Modbus (RS485) outputs as standard meaning you can connect this sensor to any established monitoring platform that accepts these protocols.
