The Hydrastep 2468 is the modern day equivalent of the site glass to monitor, display and measure the output level of the water/steam interface. For use on water tube boiler steam drums and de-aerators, the Hydrastep name has become synonymous with steam drum level measurement, and through its evolution has ensured plant safety globally for more than five decades. Assessed by an external body and found to be SIL 2 capable, according to the requirements of IEC 61508. It is recognised by boiler inspectors and plant insurers, the ASME approved design ensures Hydrastep can be used as a Remote Level Indicator in compliance with ASME Boiler Code PG60.1.1. It is also approved by Factory Mutual for boiler level control and recommended within the UK’s Combustion Engineering Association’s water tube boiler guide BG11. All of this expertise is backed up by over 6000 installations of Hydrastep around the globe.
