The Cello 4S is a remote telemetry outstation designed to reduce operating and capital costs through scalable, versatile monitoring and control. It monitors, records, and transmits multiple site parameters using 2G (SMS/GPRS), NB-IoT, and LTE Cat M1, making it suitable for a wide range of utility and industrial applications.

The device is future-ready, supporting low-power NB-IoT and LTE Cat M1 networks for improved energy efficiency. It offers flexible communications, configurable hardware with up to two pressure inputs, eight programmable digital or analogue inputs, and two independent digital outputs for alarms, power control, or 4–20 mA loop supply. Proven bidirectional communication ensures reliable data transfer with automatic gap filling and supports remote configuration.

The Cello 4S can be set up, monitored, and controlled remotely via PMAC software or the WaterCore web platform. Specific models support closed-loop control of pressure reducing and sustaining valves and variable speed pumps. Additional capabilities include water temperature measurement, advanced alarms, high-frequency pressure transient detection (100 Hz), and a low-power, rugged IP68 design suitable for battery or DC power.

Typical applications include water transmission and distribution, pressure-managed and district-metered areas, wastewater and effluent monitoring, reservoirs, rivers, weather stations, farming and irrigation, pumping stations, water extraction, treatment plants, power and energy monitoring, and customer service performance tracking.
