The Sentinel™ PRO system from Sensaphone provides water and wastewater facility operators cost-efficient 24/7 remote monitoring of equipment and environments. The Sentinel PRO system seamlessly interfaces with any water or wastewater processing equipment that uses a PLC with Modbus sensors. The system is ideal for water and wastewater professionals because it easily integrates devices, polls Modbus registers from other equipment and immediately delivers critical system-wide information. Supporting both Modbus RTU-485 and TCP protocols, the system can monitor up to 64 Modbus registers and twelve different digital or analog status conditions—including power, pump status, tank level, turbidity, flow rate, pressure, temperature, humidity, and water leaks.
