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.
Claims12
A method of calculating an attribute of water usage, comprising:
- determining, via a flow timer of a water usage meter, a flow rate of a household faucet as an interval of time over which an amount of water is consumed;
- measuring, via an electronic clock of the water usage meter, a water consumption time interval during a water consuming activity at the household faucet;
- calculating, via a central processing unit (CPU) of the water usage meter, a volume of water consumed using the flow rate and the water consumption time interval;
- and
- calculating, at the CPU, potential water savings for a future water consuming activity if at least one of the flow rate and the water consumption time interval were to be adjusted.
A water usage meter, comprising:
- a measurement system to measure a flow rate of a household faucet as an interval of time over which a defined amount of water is consumed;
- a timer to measure a water consumption time interval during a water consuming activity at the household faucet;
- and
- a calculator to calculate a volume of water consumed using the flow rate, the water consumption interval, and a potential water savings for a future water consuming activity if at least one of the flow rate and the water consumption time interval were to be adjusted.
A method of conserving water during a water consuming activity monitored by a water usage meter, comprising:
- collecting, at a central processing unit (CPU) of a water usage meter, water consumption information for a particular water supply over a period of time;
- calculating, at the CPU, whether more or less water was consumed during the water consuming activity relative to a programmed value of water consumption;
- calculating, at the CPU, and storing, in a memory coupled to the CPU, a water consumption credit if less water was consumed than a programmed value, or calculating, at the CPU, and storing, in the memory coupled to the CPU, a water consumption debit if more water was consumed than a programmed value;
- and
- applying, via a calculation at the CPU, the water consumption credit or debit to the calculation of a volume of water allocated for one or more future water-consuming activities.
