OpenFlows Hammer and Transient Analysis Software

Every time a pump or valve is operated, potentially dangerous transients are introduced in your water distribution or wastewater system. Unchecked, transients can have catastrophic consequences on your pipes and equipment, operators, and customers.
Water utilities, municipalities, and engineering firms around the world trust OpenFlows HAMMER’s computationally rigorous engine and easy-to-use interface to efficiently identify, manage, and mitigate the risks associated with transients.
