Diesel Pump Failure Prevention

Using Vibration & Temperature Monitoring (2‑Sensor IoT Solution)

Problem Statement

Diesel pumps deployed in remote and infrastructure-critical locations operate without real-time visibility. This leads to undetected failures, fuel wastage, incorrect operation logs, and delayed maintenance actions.

Ground Reality (Field Observations)

During on-site PoC at Mumbai installations, the following issues were observed:

  • Battery draining within 2 days, making continuous monitoring unreliable
  • Temperature sensor stuck at constant reading (~57°C), indicating calibration or placement issue
  • False ON/OFF detection due to lack of reliable sensing logic
  • No visibility of actual pump runtime and usage patterns
Key Insight: Traditional monitoring approaches fail because they rely on assumptions rather than actual machine behavior.

Solution Approach

Hexitronics proposes a minimal yet highly effective 2-sensor IoT solution using:

  • Vibration Sensor: Accurate detection of pump ON/OFF state based on mechanical activity
  • Temperature Sensor: Monitoring thermal behavior to identify overheating and abnormal conditions

The system is powered by an optimized battery system with provision for solar charging and transmits data periodically over a 4G network.

Sensor Logic (Core Intelligence)

  • Vibration present → Pump is ON
  • No vibration → Pump is OFF
  • Temperature rising abnormally → Potential failure or stress condition

Key Features

  • Battery-powered system with extended backup using drone-grade battery
  • Optional solar charging for long-term deployment
  • Data capture at high frequency with transmission at optimized intervals (e.g., every 5 minutes)
  • Accurate pump runtime calculation
  • Cloud-based monitoring with alerts

Future Dashboard & Analytics

The system will provide a centralized dashboard with:

  • Pump ON/OFF timeline
  • Total runtime analysis
  • Temperature trend graphs
  • Alert notifications for abnormal conditions
  • Predictive maintenance indicators (future upgrade)

Benefits

  • Eliminates false operation reporting
  • Reduces fuel wastage
  • Improves maintenance planning
  • Increases equipment reliability
  • Enables remote monitoring of distributed assets

Deployment Strategy

Step 1: Pilot deployment (PoC at one site)
Step 2: Validation of sensor logic and power system
Step 3: Scale deployment across all pump locations
