Neptune Systems FMM Flow Monitoring Module
The Neptune Systems FMM is best-in-class for flow sensing within serial-bus aquarium systems because it provides tightly integrated, low-latency data to Apex controllers and uses a galvanically isolated interface to protect the main controller from sensor-side ground loops. Compared with the other products on this list it offers a highly cost-effective upgrade path for existing Apex users — delivering precise flow analytics without the higher capital cost or heavy-duty power distribution of GHL or CoralVue solutions.
