Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Fire Water System Valve Position Monitoring (Ports & Terminals)
Readiness assurance
Valve position
Quick Overview
| Problem | Fire water systems in ports and terminals are safety-critical assets. Valves left partially closed, incorrectly positioned, or unintentionally isolated can render firefighting systems ineffective during an emergency—often without any visible indication. |
| Solution | SENSAiO’s wireless valve position sensors provide continuous, real-time visibility of fire water valve status, ensuring system readiness and compliance across port and terminal facilities. |
| Value | Guaranteed firefighting readiness • Reduced inspection effort • Improved safety compliance • Faster emergency response |
| ATEX | Typically non-ATEX; ATEX-certified valve sensors available when installed in hazardous fuel or chemical areas |
The Operational Challenge
Fire water networks in ports and terminals include:
- Main fire water ring mains
- Sectional isolation valves
- Hydrant and monitor supply valves
- Deluge and foam system isolation points
These systems are expected to remain fully operational at all times, yet common issues include:
- Valves accidentally left closed after maintenance
- Partial closure due to vibration or corrosion
- Lack of real-time visibility across large sites
- Manual inspections performed infrequently
Traditional assurance methods rely on:
- Periodic valve walkdowns
- Paper-based inspection logs
- Visual confirmation only during audits
This creates a critical gap between inspections, during which system readiness cannot be guaranteed.
Why Valve Position Monitoring Matters
Valve position directly determines whether fire water can reach hydrants, monitors, and deluge systems.
Continuous monitoring enables operators to:
- Verify that all critical valves are fully open
- Detect unauthorised or accidental valve movements
- Receive immediate alerts if a valve is closed or mispositioned
- Maintain permanent proof of system readiness
For large port and terminal sites, remote valve monitoring dramatically improves safety assurance without increasing inspection workload.

FAQ - Common Questions
Are Sensa.io sensors compatible with any gateway or network?
What ATEX certifications apply to Sensa.io devices?
All hazardous-area models are certified Ex II 2 G Ex ia IIC T4 Gb and IECEx approved for Zones 0–2.
What is the typical battery life?
Up to 10 years at 15-minute intervals, depending on signal strength and environment.
How are the sensors integrated into existing systems?
Through standard protocols — LoRaWAN, Modbus, MQTT, REST API — no proprietary middleware needed.
How does predictive maintenance reduce OPEX?
Early anomaly detection reduces emergency interventions by 30–40 %, extends equipment life and lowers energy costs.
What does the Sensa.io Valve Position Sensor actually measure?
The device detects real-time valve position states—open, closed, or intermediate—with high accuracy. It continuously sends this information wirelessly to your monitoring dashboard.
Can this sensor detect partial valve movement or stuck valves?
Yes. The sensor identifies irregular patterns such as partial movement, delayed response, or stuck valves, enabling early maintenance before failure occurs.
Is this sensor suitable for manual, motorized, and actuated valves?
Yes. It supports a wide range of valve types including ball, gate, butterfly, actuator-driven, and manual valves.
How fast does it update the valve position?
You can configure the reporting interval—from seconds to minutes—depending on your operational and battery needs.
How long does installation take?
Most installations take under 10 minutes. The sensor mounts using brackets or clamps without modifying existing valves.
