Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Fuel Transfer Pressure Monitoring (FPSO Bunkering & Transfer Safety) — ATEX
Prevents leaks, ensures safe bunkering
Pressure
Quick Overview
| Problem | Fuel transfer and bunkering operations on FPSOs and offshore platforms involve high flow rates and flammable products. Pressure instability during loading or transfer can cause hose rupture, spills, fire risk, and emergency shutdowns in ATEX-classified areas. |
| Solution | SENSAiO’s ATEX-certified pressure sensors provide continuous, wireless monitoring of fuel transfer pressure to ensure safe, controlled bunkering and transfer operations. |
| Value | Reduced spill risk • Improved transfer safety • Faster operations • Enhanced ATEX compliance |
| ATEX | Zones 0–2 • Ex ia IIC T4 Gb certified pressure sensors |
The Operational Challenge
Fuel transfer operations offshore include:
- FPSO bunkering from supply vessels
- Fuel oil transfer between tanks
- Diesel distribution to generators and utilities
These operations are exposed to:
- Rapid pressure transients
- Hose and coupling stress
- Human error during valve sequencing
- Limited visibility from control rooms
Common risks include:
- Overpressure leading to hose or flange failure
- Undetected pressure loss indicating leaks
- Delayed shutdown response during abnormal events
Traditional monitoring often relies on:
- Local pressure gauges
- Manual radio communication
- Visual observation during transfer
These methods provide limited real-time visibility and increase personnel exposure in hazardous zones.
Why Fuel Transfer Pressure Monitoring Matters
Pressure is the primary safety indicator during bunkering and transfer.
Continuous pressure monitoring enables operators to:
- Detect abnormal pressure rise or drop instantly
- Prevent hose rupture and fuel spills
- Ensure controlled flow rates
- Trigger immediate shutdown during unsafe conditions
Remote monitoring reduces the need for personnel presence near pressurised fuel lines and improves response speed during critical operations.

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.
