The Aquadopp is probably the most versatile single-point current meter on the market. It is cost-effective, robust and has a wide range of applications. The system electronics integrates accurate Doppler velocity measurements with standard sensors such as temperature, pressure, tilt, and compass. It is low maintenance, has no moving parts, requires no recalibration, and has no zero-point drift over time. The instrument can be used in real-time applications but also comes standard with an internal recorder, batteries and a highly sophisticated power management that makes it the system of choice for self-contained deployments.
