Fuel Hydrant Valve & Pressure Monitoring (Airports & Aviation Fuel Systems) — ATEX
Prevents leaks, improves traceability
Valve position
Pressure
Quick Overview
| Problem | Aviation fuel hydrant systems operate under strict safety and availability constraints. Undetected valve mispositioning, pressure instability, or leaks can disrupt aircraft refuelling, create safety hazards, and lead to costly operational delays in ATEX-classified fuel zones. |
| Solution | SENSAiO’s ATEX-certified valve position and pressure sensors provide continuous monitoring of hydrant valves and fuel line pressure, ensuring safe, traceable, and reliable airport refuelling operations. |
| Value | Improved refuelling safety • Reduced delays • Lower inspection effort • Higher operational reliability |
| ATEX | Zones 0–2 • Ex ia IIC T4 Gb certified valve & pressure sensors |
The Operational Challenge
Aviation fuel hydrant systems supply fuel to:
- Aircraft stands and aprons
- Refuelling pits and hydrant valves
- Underground fuel distribution networks
- Backup and emergency refuelling points
These systems operate continuously and are exposed to:
- Frequent valve operations
- High flow rates and pressure variations
- Strict aviation safety regulations
- ATEX-classified environments
Common issues include:
- Valves left partially open or closed
- Pressure instability during refuelling
- Undetected leaks or line degradation
- Manual verification of valve status
Traditional monitoring relies on:
- Visual valve position checks
- Local pressure gauges
- Manual logging for compliance
This approach is labour-intensive and prone to human error.
Why Valve Position & Pressure Monitoring Matters
Valve position and line pressure are critical parameters for aviation fuel safety.
Continuous monitoring enables operators to:
- Verify correct valve position in real time
- Detect abnormal pressure drops or surges
- Ensure consistent refuelling conditions
- Maintain traceability for audits and incident analysis
Remote monitoring also reduces personnel exposure on aprons and in fuel pits.

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.
