Hydrastep 2468 Steam Boiler Water Level Monitoring

Hydrastep 2468 steam boiler water level monitoring controller

Fault Tolerant & Fail-Safe Design

Globally trusted steam drum level monitoring system for water tube boilers

With diagnostics to detect all fault conditions and over 6,000 installations globally, the Delta Mobrey Hydrastep™ 2468 steam drum level monitoring system for water tube boilers provides a critical fail-safe to detect low water levels in steam-raising applications.

 

Globally trusted for both remote and local steam drum water level indication, the fault tolerant and fail-safe design provides a highly visible solution with alarms to avoid costly and potentially disastrous consequences, while aiding compliance with legislation.

Features & Benefits

 

Failure to detect low water levels in steam raising plant can have costly and potentially disastrous consequences. Fail-safe water level detection is vital to prevent damage to plant and personnel.

 

Trusted globally for 50 years, the Hydrastep electronic gauging system is the ideal ‘fit and forget’ solution to overcome the problems associated with unreliable and maintenance-intensive gauge glasses.

 

Independently Validated

 

An independent report by Factory Mutual Research concluded that the statistical probability of Hydrastep missing a trip condition is less than 1 in 300 million and that nuisance trips will be less than 1 in 10 million.
