Introduction

In today’s data-driven world, manual records and handwritten labels are no longer enough. With the increasing importance of traceability, compliance, and speed in asset maintenance, barcode-based oil sampling has become a game-changer. This blog explores how Tru-FIL Ltd is modernizing transformer oil sampling using barcode technology, mobile apps, and ERP integration.

Traditional Sampling vs. Modern Sampling

Old methods involved:

• Manual entry of transformer details

• Labeling bottles by hand

• Lack of location traceability

• Human errors during sample identification

• Missing or delayed lab reports

Modern barcode-based sampling eliminates all of these pain points by digitizing the entire sample lifecycle — from collection to report delivery.

How It Works at Tru-FIL Ltd

1. 📋 Functional Location Mapping
   Each customer’s transformers are pre-configured in our ERP with their exact location, equipment ID, and asset metadata.

2. 📲 Mobile App Sampling
   Technicians use a mobile app to select the customer, asset, and sample point. The app guides the technician through bottle usage and barcode scanning.

3. 🔖 Barcode-Tagged Vacuum Bottles
   Every sample bottle has a unique barcode. Once scanned, it is digitally linked to the asset and timestamped in the system — ensuring traceability.

4. 🚚 Digital Gate Pass & Dispatch
   After collection, a system-generated gate pass is printed. All bottles are dispatched to our lab and virtually logged into a customer-specific ERP warehouse.

5. 🧪 Lab Receipt & Processing
   Upon lab receipt, the bottles are scanned again. Our AI-integrated ERP assigns tests like DGA, Furan, Moisture, etc., based on the asset type.

6. 📄 Automated Reporting
   Once testing is complete, the system auto-generates reports and pushes them to the customer portal with download links and alert emails.
