Sentinel is the physical intelligence layer of FlowGuard — connected hardware designed to observe the conditions that influence flood and drainage risk. Monitor the infrastructure. Understand the risk. Act earlier.
Real-time drainage intelligence — visibility-first for estates that want continuous eyes on their network.
Everything the Monitor does — plus fully managed monitoring, scheduled maintenance and coordinated response handled by FlowGuard.
Every Sentinel reports continuously — the raw signal behind FlowGuard's risk intelligence.
