38 UTILITY METER INTERFACE CIRCUIT ABSTRACT OF THE DISCLOSURE 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.
