Mobrey™ Hydrastep 2468 Electronic Steam and Water Guaging System

Mobrey

Use the Hydrastep water and steam monitoring system for highly visible local and remote drum level indication, including alarms, with exceptional reliability. Failure to detect low water levels in steam-raising operations can have costly and potentially disasterous consequences. According to Factory Mutual Research, " the probability of Hydrastep missing an actual trip is less than 1 in 300 million. The probability of creating a nuisance trip is less than 1 in 10 million."
