Seba PS-Light-2 Bubbler

A robust, economic and reliable bubbler measuring system for monitoring water level.

An integrated, highly efficient mini compressor, bubbles air through the pressure tube into the water at adjustable intervals. The resultant pressure in the tube corresponds exactly to the hydrostatic pressure above the mouthpiece.This tube pressure is then measured by a very accurate pressure sensor.

The intermittent operation of the PS-Light-2 ensures low energy consumption, and enables operation with batteries or solar panels.

The basic version of is a sensor with optional analogue or serial output. It can also be equipped with LC-display, datalogger or remote data transfer via GSM/GPRS.

The PS-Light-2 can be connected to existing pressure tubes at any time.
