Intended for tank level monitoring, SignalFire Remote Sensing System™ integrates open architecture mesh network that allows users to choose preferred sensor type for application as well as mix sensor types in same network. System communicates and powers virtually any sensor with 4–20 mA, 1–5 V, Modbus, Hart, digital IO, and other analog and digital interfaces. Because SFRSS mesh network operates at lower frequencies, it can communicate at ranges of up to 3 miles between nodes.
