Handy precision pressure, flow velocity and volume data transmitter

ABOUT

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. 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.
