In view of the recent rapid development of coastal engineering in our country and to fill the urgent demand for a suitable current meter to measure near surface currents

the Ocean University of Qingdao designed a propeller type SLC9-2 Direct Reading Current Meter of excellent dynamic characteristics and not much affected by waves. The model is rationally designed

small and light

stable and reliable in operation

and economical in power consumption. It can be used to measure current speed and direction in near surface layers

especially in ultra-shallow water in oceans

rivers

lakes

reservoirs

estuaries

and ports. This paper focuses on the major properties

technical cruxes

experimental results

and applications of the model and touches briefly on its dynamic effectiveness with horizontal formations.
