Water Level

Water Level Sensing Technology

Measuring water level is one of the most common surface water quantity measurements which is typically used for developing and computing stage discharge relationships or controlling water resources.

Continuous, real-time measurements and images can provide flood warning information, including alarms, for water levels that hit or exceed critical threshold levels to prompt manual or automatic responses such as evacuations during flooding and field operations.

OTT HydroMet develops and manufactures water level sensing technology, evolving system solutions from mechanical and labor-intensive to low maintenance.

Offering Contact and Non-Contact Surface Water level Sensors

OTT HydroMet's two leading brands - OTT and SUTRON, offer contact and non-contact surface water level sensors featuring a variety of measurement technologies (radar, bubbler, pressure) to meet stream gaging needs for reliable data.
