Energy/Water Usage Monitor
First Claim
1. An energy/water usage monitor adapted to be connected into a water line, said monitor includinga temperature sensor to sense the temperature of the water in the water line,a water flow sensor to continuously calculate the volume of water flowing through the water line,a microprocessor to receive information from the temperature sensor and the water flow sensor and to compare the average temperature of the water against the total flow of water and to calculate a continuous estimate of the energy/water usage consisting of a combination of the average temperature of the water and the total volume of water in the water line and to provide a signal when the estimated energy/usage is approaching or has approached a programmed level.

Abstract
A water/energy usage monitor for insertion into a hot water line. The monitor continuously records the flow of water and the temperature of the water in the hot water line by means of a flow sensor and a temperature sensor and calculates the energy used. When the energy used reaches a programmed level, the monitor will issue a signal.

19. An energy/water usage monitor adapted to continuously estimate the energy/water usage in water flowing through a pipe during the duration of a sampling period, said monitor including:
-
means to preset the duration of the sampling period, means to continuously estimate the flow of water through the pipe throughout the sampling period means to preset the desired temperature values of the water flowing through the pipe throughout the sampling period, and means to estimate the energy/water usage based on the combination of an estimate of the total flow of water through the pipe during the sampling period and the average temperature of the water flowing through the pipe during the sampling period, and means to display the estimated energy water usage. - View Dependent Claims (20, 21, 22, 23, 24, 25)
