SEBA PS-Light 2 Bubbler

The new intelligent bubbler device measures water level fluctuations in rivers, channels and reservoirs. As sensor with galvanically seperated outputs ( 4-20 mA, gray, BCD code ) or with integrated data logger and GSM / GPRS modem. Measuring range: 0-10, 20,30,50,70 m ( with 1 cm accuracy ).


The OTT ADC (Portable Acoustic Digital Current Meter) is designed for point velocity measurements in natural streams, rivers, creeks and open channels. Using the latest acoustic measuring principles and combined with a high end signal processor the instrument provides accurate and reliable data.



MAGELLAN PROMARK™ 500
The winning combination
The new ProMark™ 500 offers GPS+GLONASS+20 years of field-proven Magellan technologies. Designed by our GNSS experts, this powerful survey solution delivers state-of-the art RTK features in a light, cable-free rover that gives you maximum mobility and flexibility in the field. Its unique GNSS engine insures fast initialization, long-range accuracy, robust signal tracking, and secures future constellation evolutions.


MAGELLAN PROMARK™3 RTK operates in two modes; base + rover and rover only. The rover can be connected to a real-time network through a GPRS-enabled cell phone using NTRIP and direct IP. The second mode of RTK operation, base + rover, employs an efficient plug-and-play spread-spectrum radio solution that does not require a license or separate configuration integrated with ProMark3 RTK.
