The Aquaread LeveLine is a self-contained titanium water level and temperature logger for groundwater and surface water. A ceramic piezoresistive level sensor, temperature sensor, 10-year lithium battery and a datalogger with room for 500,000 readings sit inside a sealed titanium body with a Delrin nose cone that helps keep the pressure sensor free of fouling. It reads up to 10 times per second, so it suits slug tests and pumping tests as well as multi-year monitoring.

Choose an absolute (non-vented) logger, which needs a LeveLine-Baro or barometric data to compensate for air pressure, or a gauge (vented) logger that runs on a vented cable and compensates on its own. Both ship with a socket for the cable, with SDI-12 and Modbus (RS485) outputs for direct connection to telemetry and SCADA, plus an external 6–30 V supply input for batteries or solar. Set up and download with the LeveLink PC software, a QuickDeploy Key or a GPS LeveLine meter.
