Irrigation Filter ΔP Monitoring (Clogging Prevention & Water Efficiency)
Optimizes maintenance cycles
Differential Pressure (ΔP)
Quick Overview
| Problem | Irrigation filters protect drip lines, sprinklers, and fertigation systems from clogging caused by sand, silt, algae, or organic matter. Progressive clogging increases differential pressure (ΔP), reduces flow uniformity, and leads to uneven irrigation, crop stress, and higher pumping energy—often detected too late through manual checks. |
| Solution | Sensa.io’s wireless differential pressure (ΔP) sensors continuously monitor irrigation filters, detecting clogging early and enabling timely cleaning or backwashing to maintain uniform water distribution. |
| Value | Uniform irrigation • Reduced water waste • Lower energy consumption • Protected crop yield |
| ATEX | Generally non-ATEX; ATEX-certified ΔP sensor variants available near fertiliser injection or dust-prone areas |
The Operational Challenge
Irrigation filtration systems are critical in:
- Drip and micro-irrigation networks
- Sprinkler and pivot systems
- Fertigation and reclaimed-water irrigation
- Greenhouses and open-field agriculture
They face recurring challenges:
- Gradual clogging from suspended solids
- Biofouling and algae growth
- Pressure loss across long distribution networks
- Manual cleaning triggered too late or too often
Common consequences include:
- Uneven emitter flow rates
- Localised under- or over-irrigation
- Increased pump load and energy use
- Premature wear of irrigation components
Traditional monitoring relies on:
- Manual pressure gauge readings
- Visual inspection during maintenance rounds
- Fixed backwash schedules
These approaches lack precision and waste water and energy.
Why Differential Pressure Monitoring Matters
ΔP is the most accurate indicator of filter condition.
Continuous ΔP monitoring enables operators to:
- Detect progressive clogging in real time
- Trigger cleaning or backwash only when needed
- Maintain stable pressure and flow uniformity
- Protect downstream emitters from blockage
Optimising filter maintenance directly improves irrigation efficiency and crop performance.

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.
