A portable current meter for accurate current speed measurement and suitable for use by an individual in natural streams was devised. The meter consists of a sensor with a four-bladed propeller (30 mm diameter), a photo coupler and a counting apparatus (a modification of the 3631 rotation meter : Yokogawa Hokushin Electric). A high accuracy of calibrations was obtained under laboratory conditions, and its reliability and operability were also tested at a natural stream.
