LOG_aLevel Mobile is an easy to carry, plug and play, stand-alone remote sensing water level gauge. Based on the well-known and proven LOG_aLevel system, this unit is also calibration-free, accurate, durable and very cost-effective. LOG_aLevel Mobile measures reliably and precisely water level and all kinds of water surface dynamics. It can work with Ultrasound, Radar or Pressure sensors. LOG_aLevel can be easily extended to include a Datalogger, Data Communication systems and additional hydrological and meteorological system to form a complete monitoring station. Furthermore, multiple LOG_aLevel stations can be interconnected to form a network. Integration in SCADA systems is straightforward.
