Handheld 1-D electro-magnetic current meter for rivers AEM1-DA

AEM1-DA is a 1-D electro-magnetic (EM) current meter for the flow measurements in rivers, streams and various waterways. The measurement range is 0 to 5m s-1. The EM sensor can accurately measure water speeds at a shallow depth of 3cm. The display unit has a 2MB flash memory so that the data are saved with calendar information (up to 255 station data). In comparison with conventional propeller-type current meter, AEM1-DA is robust and extremely easy to be operated and maintained.
