The Virtual Make “Water Velocity Logger” Model: DVI-K20 is a small electronic hand-held device that can be used to measure flow velocity from mechanically rotating current meter. A superior feature of the DVI-K20 is its ability to store up-to five current meters data at a time and interface directly to a Laptop, Pocket-PC, or other computing device and provide data in MS-Excel File Format that can be used externally to compute discharge. Current Meters perform a mechanical switch closure can be used with the DVI-K20 to produce a clean, noise-free signal. To measure and compute velocity, the DVI-K20 provides flexibility to User to Program it for upto 5 Current meters calibration equation with up to 3 rating equations for each current meter. USB port is provided for data downloading from terminal to Computer/Laptop. Data file is saved in Microsoft’s Excel Format.
