Depth Meter for Online Operation

This light and handy measuring instrument provides accurate pressure, flow velocity and volume data during operations of plankton nets for limological and oceanographic applications.

The 2 Electronic Flow Meters to measure flow velocity and volume are ideal to be operated with either single-ring plankton nets or double-ring plankton nets. The integrated long-distance telemetry can be used via electro-mechanical towing cables of more than 10000 m length.

The system consists of a titanium pressure housing with integrated pressure sensor, electronics, rechargeable batteries and two Electronic Flow Meters. A splash-proof hand unit is the link between underwater unit and PC during the operations.

• Salient features:

The state-of-the-art electronics, optimised in power consumption, are designed for ambient temperatures from -40°C up to +85°C. The system is rated to a maximum operational depth of 3000 meters. The Depth Meter is delivered with the data acquisition software OceanLab 3, an easy-to-use package for pre-deployment system set-up, real-time data acquisition, data visualisation, storing and export.
