Project Status: Phase 1 (Live Testing & Validation)
Category: Industrial Automation, IIoT, Custom Software Development
The Challenge
In high-volume industrial fluid application, the gap between "what was planned" and "what was applied" is often where efficiency is lost. Many operations still rely on manual gauge reading and paper logbooks, leading to data entry errors, lack of accountability, and delayed reporting.
JAZ Engineering was tasked with digitizing this workflow. The goal: create a robust, hardware-integrated solution to monitor flow rates in real-time, enforce health and safety compliance, and automate the generation of audit-ready reports without disrupting the operator's workflow.
The Solution: Intelligent Edge Monitoring
We designed a custom Industrial Internet of Things (IIoT) solution that interfaces directly with existing flow hardware. By bridging the gap between mechanical sensors and modern web technologies, we created a system that offers precision monitoring and airtight data integrity.
Key Features
1. Real-Time Flow Monitoring & Calibration At the core of the system is a high-frequency pulse detection engine. The software interfaces with industrial flow meters to calculate:
Live Flow Rate: Displayed in an intuitive digital gauge for operators.
Volumetric Tracking: Precise tracking of total liters applied against specific job setpoints.
Dynamic Calibration: The system allows Admins to fine-tune "pulses per liter" settings, ensuring accuracy regardless of fluid viscosity or hardware wear.
2. Enforced Health & Safety Compliance Safety is not optional. We built a mandatory "Digital Gatekeeper" into the workflow. Before a job can commence, the operator must complete a digital Health & Safety (H&S) checklist.
Logic-Driven: The system validates answers (e.g., ensuring PPE is worn and machinery is grounded) before unlocking the machinery controls.
Audit Trail: Every checklist is timestamped, tied to a specific user, and logged in the database for liability protection.
3. Automated Reporting & Digital Signatures Eliminating paper trails was a priority. Upon job completion, the system automatically generates a comprehensive PDF report.
Electronic Signatures: Integrated signature pads allow the Farm Manager and Team Leader to sign off directly on the device.
Smart Calculations: The system automatically calculates chemical ratios and application rates based on the actual flow data, reducing human calculation errors.
Instant Delivery: Reports are saved locally and can be emailed immediately upon completion.
4. Role-Based Dashboards The software features distinct interfaces tailored to the user:
Operator View: Large, touch-friendly buttons and clear gauges designed for use with gloves in industrial environments.
Admin View: A dense data dashboard for configuring system settings, managing user credentials, and analyzing historical logs.
5. Remote Connectivity & VPN Integration To ensure maximum uptime, the system is deployed with a secure VPN tunnel. This allows JAZ Engineering to perform remote diagnostics, push software updates, and troubleshoot sensor data without requiring a site visit, significantly lowering maintenance costs.
Technical Architecture
The system utilizes a lightweight, robust software stack designed for edge computing:
Backend: Python & Flask for reliable hardware interrupt handling and data processing.
Database: SQLite/SQLAlchemy for efficient local data storage.
Real-Time Communication: WebSockets for millisecond-latency updates between the hardware sensors and the operator's screen.
Hardware Interface: Direct GPIO integration for reading sensor pulse outputs.
Future Roadmap: From Monitoring to Control
With Phase 1 currently in the validation and testing stage, the foundation has been laid for a fully autonomous system.
Phase 2 Development will transition the system from Passive Monitoring to Active Control. Planned features include:
Actuator Control: Direct relay control of pumps and solenoid valves based on flow logic.
Automated Setpoints: The system will automatically close valves once target volumes are reached, eliminating over-application.
Pressure Regulation: Integration with pressure transducers to automate safety cut-offs.
Conclusion
This project exemplifies JAZ Engineering’s ability to deliver end-to-end industrial solutions. By combining mechanical engineering knowledge with full-stack software development, we help businesses transition from analog estimation to digital precision.
