Electric Water Feeder
The Electric Water Feeder (EWF), is an electronics based water feeder for steam boilers. The EWF monitors the output from a Low Water Cutoff (LWCO). When the LWCO detects a low water condition, it signals the EWF, which initiates a water-feed cycle. Since the EWF is fully programmable, it can feed as long as the low water cutoff detects a low water condition (LWCO mode) or fixed feed amounts. In addition, the EWF allows the user to set Delays Before Feeding (DBF), or hold delays after the low water cutoff signals water is restored (HAW). The EWF also includes a programmable excess feed indicator, (patent pending). The EWF blinks this LED after it has fed more than a settable number of gallons into the boiler over the past 30 days. This will help identify systems that may need maintenance.
