Water Current Meter

A device that can measure flow-velocity up to 9 mtr/sec with a resolution of 0.01. It will provide a local read-out for instantaneous, average, maximum and minimum flow rates.

The time-window over which the maximum and minimum is calculated, is user-activated. The measurement range can be configured from 1.01 up to 9.00 m/s in steps of 1.

The raw data (instantaneous, average, minimum and maximum) is stored in a micro SD card in CSV format with time-stamp. The sensor is a magnetic pickup that has 24 poles coupled with a hall-effect sensor to give better resolution and accuracy.
