ABSTRACT:
A battery powered, low voltage faucet flow timer, water usage calculator, and energy consumption awareness meter is simple to install and calibrate and may enable a user to understand the water usage associated with showering, bathing or other open faucet water use activity. The device may provide a simple method for calculating the flow characteristics for a shower, bath or other faucet and entering this flow rate into the timing device so that the timer provides an accurate calculation of water usage indicating both the time spent with the water running and approximate total water usage.
