Boiler Feedwater | Instrumart

Feedwater is essential to boiler operations. As water is heated to steam and circulated throughout the system, it must be resupplied from returning condensate or, sometimes, from fresh water. Flow meters are useful for measuring the flow rates of both steam and feedwater. As water flows throughout the boiler its chemical properties can damage the system so feedwater is often treated to control alkalinity, prevent scaling, correct pH, and to control conductivity.
