| Specification
This Micro-controller based Direct Velocity Indicator has been designed to measure the Velocity of water in a flowing stream. It uses the latest Microchip’s Micro-controller and can be used with any calibrated Water Current Meter. The velocity of water is calculated as per the calibration equation provided with the Sensor and displayed on the 16x2 LCD display. The Velocity Indicator consists of 4x1 tactile membrane keypad mounted on the front panel. You can save upto 56 readings . Two terminals to connect the current meter sensor are provided on the top. One power connector for charging adopter is also pro-vided.
