AEM1-D is an in-situ portable single-axis current meter designed for accurate and simple measurements of current velocity at rivers and canals. Accurate velocity measurement can be obtained even at shallow depth of 3 cm. In comparison with conventional propeller current meters, this instrument is trouble-free and simple to operate and maintain. The rugged display unit gives the digital output of current speed, ranging from 1mm/s to 5m/s.
As one of the new features, a memory function stores the measured data together with calendar information. Data of up to 99 different field locations can be stored in the memory. All data can be transferred into a PC and processed conveniently.
