Diesel & General is the appointed contractor as the agent for PetroMonitor in the Eastern Cape.

PetroMonitor is the leading wetstock management, tank testing, and tank cleaning company of underground storage tanks in South Africa. Our technologies enable major oil companies and independent fuel retailers to achieve the tightest storage systems, lowest fuel losses, and most accurate wetstock management.

Our Services Include:

1. UST Installation Integrity Testing

The world's most accurate tank & line test. Most fuel storage system issues including water ingress, small leaks and weeps from pipes, fittings and vents stem from the date of the original tank installation. These issues are often too difficult to address after commissioning, resulting in costly maintenance issues over the life of the asset.

PetroMonitor offers the world’s most accurate tank and line test for new underground storage tank (UST) installations or following repair, maintenance or upgrade of an existing UST. We utilise US EPA-certified technology from Leighton O’Brien International Pty Ltd to detect spillage leaks equivalent to 0.095 litres per hour, making it 4 times more accurate than the current USA required fuel leak detection.

How it Works

Our testing process guarantees a perfectly tight UST, meaning zero water ingress, zero leakage, zero vapour loss from tank and line system breaches of any kind, and eliminates vapour emissions.

Key Features & Benefits

  • Identifies water ingress, manway leaks, primary and secondary piping issues often missed by pressure gauge tests
  • All lines can be tested including product lines, vent lines and filler lines
  • 3rd party independent testing
  • Ensures a 100% leak-free system from Day 1

2. Wetstock Management

Wetstock Live™ - The smartest wetstock intelligence. When the high cost of fuel and low margins are considered, continuous fuel leak detection in the form of statistical inventory reconciliation (SIR) is a business tool no commercial fuel retailer or user can afford not to use.

PetroMonitor offers the most precise, practical and cost-effective wetstock management solutions for fuel leak detection to most accurate detection with exclusive access to Leighton O’Brien International Pty Ltd Wetstock Live™technology.

Wetstock Live™ provides real-time, accurate and actionable network-level wetstock information for all brands of equipment. It unifies all elements of wetstock including ATG accuracy and functionality, pump flow rates and pump accuracy, delivery validation, wetstock replenishment and water ingress onto one software platform.

How it Works

Our wetstock management service is built on statistical analysis of normal fuel stock data such as sales, deliveries, and stock-on-hand (dips). These figures are recorded for certified leak detection using SIR in monthly, daily or real-time analysis.

Key Features & Benefits

  • Leak detection: Certified as the most accurate provider of fuel data analysis and reporting, our expert wetstock analysts detect fuel losses as low as 0.45 litres per hour with greater than 99.6% accuracy.
  • Dispenser performance: Live pump flow rate monitoring of all dispensers regardless of brand, with live detection and data reporting of any reduced flow dispensers;
  • Meter drift analysis: Drifting meters is a primary cause of fuel loss. Meter drift is monitored and assessed for the accuracy of dispensing, we also assess meter downtime, and dispensers not in operation are identified for action;
  • Water management: Live network monitoring of water levels and analysis of any water ingress;
  • ATG monitoring: Continuous accuracy and assessment of all brands of gauges at a network level – remote tank monitoring, live management and correction of all ATG’s to an accuracy of 0.3% of delivered volume;
  • Delivery validation: Every delivery in your network is assessed to an accuracy of 0.3%. Virtually eliminating short deliveries, and holding your transport company to account;
  • Hose-to-tank mapping: Analysis of 1 billion possible permutations to achieve correct pump tank mapping, correct POS configuration issues and understand every single loss and gain.

3. Tank and Pipe Integrity Testing

Fast, accurate digital leak detection. Traditionally, tank integrity testing is used to meet legal requirements and regulations or react to a problem onsite. This approach is changing. Tank and line testing carried out by PetroMonitor can be used to prevent costly maintenance and repairs. With early detection, leaking underground storage tanks can be acted upon quickly to prevent costly fuel loss and environmental liability. PetroMonitor offers a nationwide tank and line integrity testing service that utilizes US EPA-certified technology from Leighton O'Brien International Pty Ltd. Mass readings are digitally measured, stored and reported, making it a fully-automated, reliable and accurate test.

Our test also provides instant technician feedback, enabling quicker onsite diagnosis and resolution of leaks, so we can be off your site faster. And unlike other test methods, our precision test is not impacted by temperature, atmospheric conditions, vapour pockets or ambient noise. There is no fuel leak scenario that our test method cannot detect.

How it Works

The test is a mass-based volumetric tightness test that records continuous readings from all parts of the underground storage tank and associated pipework, providing real-time feedback on system integrity.

Key Features & Benefits

  • The fastest, most advances leak detection for fuel systems
  • Eliminate 100% of fuel leaks and water ingress
  • The world’s only US EPA-certified dry line test
  • Line test results in as little as 3 mins, tank test in 1 hour
  • 100% independent 3rd party engineer-reviewed results
