AIR-Plus level probe unit

AIR-Plus level probe unit

The digital level probe unit AIR-PLUS measures the level changes during leak tests with water performed in separators, small sewage tanks, manholes, and vessels. It measures the water loss or water gain against the zero water level determined before.

The height-adjustable telescopic tripod with guiding tube ensures the stable sensor installation for a exact measurement (maybe coupled up to an immersion depth of 2.2 m)


Special features:

  • Recommended for leak inspections with water in separators (according to standard DIN 1999-100), small sewer systems (acc. to standard DIN EN 12566-3), manholes and manholes with addition inlets (e. g. for house connections) (acc. to standard DIN EN 1610;ATV-M 143 Part 6) and vessels
