SebaPlus Radar Water Level Meter

1. Product Introduction

The PS-LightⅡ series bubble water level gauge is a bubble-type water level instrument that eliminates the need for bulky nitrogen cylinders and desiccants. It is a high-precision water level sensor originally manufactured by the German company SEBA. It is primarily used in areas where it is inconvenient to construct a well or where well construction is costly, such as reservoir water levels, surge tank water levels in hydropower plants, dam piezometric tubes, and upstream/downstream water level monitoring. The PS-LightⅡ series bubble water level gauge is compact in size, featuring easy installation and maintenance, flexible operation, and high accuracy. It is an ideal water level monitoring instrument for telemetry systems and non-well water level measurement.

Compared to traditional third-generation bubble water level gauges, the PS-LightⅡ series does not require air path desiccants or calibration coefficients. Its higher precision design greatly facilitates users, enabling truly maintenance-free long-term unattended operation after installation and debugging.
