Portable flow velocity indicator

This portable device is a point-by-point measuring instrument for assessing the current speeds in running waters. The RHCM ('rod held current meter') consists of a hydrometric three-blade impeller at the lower end of a telescopic rod and a splash-proof Hand Terminal. The measuring head can be angled up to ±90°.

The measuring values are displayed together with a date and time stamp on a hand terminal. They can be stored and transferred to a PC by means of the software OceanLab 3. At the PC the measuring files are stored in ASCII format for processing with current word processing, spread sheet and database software.
