About This Item

 

Full Description

This standard sets performance requirements for low water level controls used on boilers and feedwater vessels to protect against abnormal (below minimum safe) water level. They are intended to operate electrical contacts to provide an alarm and burner shutdown in the event of loss of primary water level. Low water level conditions may result in boiler destruction by overheating.
