Surface Water

Measuring water quantity and quality in surface water (open channels, rivers, reservoirs, lakes, and estuaries) is one of the foundations of hydrological monitoring and has been a focus of OTT Hydromet since its first  water current meters were designed in 1875.

OTT Hydromet provides versatile technology options for measurement of water level, flow/discharge, and water quality in surface water applications:

• OTT surface water level sensors featuring a variety of measurement technologies (radar, bubbler, pressure) to meet many application needs
• OTT current meters to measure surface water flow and discharge, with options for in-stream portable measurement or fixed installations
• Hydrolab mulitparameter sondes for measurement of water quality either in spot sampling or unattended in real-time
• Sea-Bird Coastal instruments for unattended nutrient water quality measurement
