ABSTRACT:
An interface to facilitate storing in an electric utility meter transponder, water usage data so that when remotely interrogated, access can be had to both electric and water usage data. A pulse indicative of water usage sets a magnetic latching relay in the interface circuit which causes a transponder supply voltage to be switched to two interface circuit timers. The first timer generates a first delay, after which the electric meter transponder is pulsed to register water usage. After a second, longer delay, the second timer resets the magnetic latching relay to thereby place the interface circuit in condition for receiving another water usage signal.
