Timer Adapters

Many utilities still have a water heater rate that is timer based and controlled by meters with built-in time clocks. These old time clock meters are difficult to repair or replace. The April 2001 copy of Marwell News offered one possible solution – relay adapters to be controlled by programmable meters. Another possible solution is a timer adapter.

The timer adapters can be programmed in your shop and delivered to the site ready for a plug and run installation. They can be fitted under any meter, including AMR equipped meters. Seven day scheduling is standard and automatic daylight savings time compensation is available. A simple solution for an old problem.
