System Description
The SEBA Surfloat-2 is a data logger with integrated rugged, float-driven encoder for measurement and storage of water level fluctuations.
As a "stand-alone" instrument, the Surfloat-2 can be operated with float & counter weight and also with the reliable float cable which is free of slip and slide effects.
Furthermore, the Surfloat-2 is perfectly suitable for adaptation to all conventional float operated water level recorders (e.g. SEBA strip-chart water level recorder Delta, XI Horizontal water level recorder, etc.).
The Surfloat-2 is now standardly equipped with an LC-display and an RS232 interface.
Thanks to the LC display, it allows customer friendly handling: if the LC display is activated and if the float-wheel is turned simultaneously, the desired measuring value can be adjusted by the customer. The instrument can be operated by an external and internal power supply. In case of an external
