System Description

The SEBA Surfloat-Sensor 2 sensor is a rugged, float-driven encoder for recording the water level. As a "stand-alone" instrument, the Surfloat-Sensor 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-Sensor 2 is perfectly suitable for all conventional float operated water level recorders (e.g. SEBA Delta, XI Horizontal gauge, etc.).

The standard Surfloat-Sensor 2 is equipped with an LC-display and an RS232 & RS485 interface. Optionally a parallel or analogue interface (BCD, Gray code, Binary code) can be added to this system. 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 power supply, the built-in lithium cell serves as a back up system and emergency supply.
