The measuring instrument ACROSENSOR ULG o03 is dedicated to outdoor measurements, through an ultrasonic transducer, of level. It can be adopted for various level measurements in the field of the environmental monitoring: the most commons are the hydrometrical and the snow levels.

The instrument offers a resolution of 1 mm. (higher than what ULG o02 offered) and a wide range of measure (0-1000 cm.). The signal is opportunely compensated in temperature with an external thermometer (directly linked with the level transducer) in order to ensure the proper registration of the levels even with different atmospheric conditions.

In the standard mode, the ACROSENSOR ULG o02 sends a signal through a serial cable (RS232) to the ACRONET Station which can be easily interfaced with (all equipped with configurable serial ports).

Thanks to its compactness, it can be easily installed on civil structures (light poles, pylons) by using standard fasteners or with appropriate support structure (masts, outreaches, etc.).
