South Africa's #1 Flow Verification Experts

Our VPFlowScope M ultrasonic flow meters provide accuracy within ±0.5% of reading for liquid flow measurements, while our thermal mass flow meters for gas measurements achieve ±1% accuracy. Our Meatrol ME440 Three Phase Energy Logger offers IEC62053-22 Class 0.5 accuracy for electrical measurements. All equipment is calibrated to international standards (ISO 9001) and we provide calibration certificates with every measurement. Our ultrasonic thickness gauges offer ±0.1mm accuracy for material thickness measurements across steel, aluminum, copper, and other industrial materials.

We specialize in comprehensive audits of compressed air systems, gas distribution networks (nitrogen, oxygen, CO2, natural gas), liquid flow systems (water, oil, chemicals), material thickness analysis (steel, aluminum, copper), and three-phase electrical systems. Our VPFlowScope M handles liquid flow verification, thermal mass flow meters measure gas flows, ultrasonic thickness gauges analyze material integrity, and our Meatrol ME440 provides power quality analysis. Our services cover single-point measurements, complete system audits, or multi-system evaluations across mining, manufacturing, power generation, and chemical processing industries.

For standard measurements, we can typically mobilize within 48-72 hours. Emergency services are available within 24 hours for critical situations. Our team is based in Johannesburg and can service locations across South Africa. Travel time and accommodation costs are included in our transparent pricing structure.

Our comprehensive reports include detailed measurement data with timestamps, system performance analysis, energy consumption calculations, leak detection results, efficiency recommendations, and optimization suggestions. Reports are delivered within 5 business days and include photographic documentation, data charts, and actionable recommendations for system improvements.

Most of our measurements are non-invasive and can be performed while systems are operational. Our ultrasonic flow meters use clamp-on technology that doesn't require pipe cutting or system shutdowns. Gas measurements require 1" ball valve measuring points but can be installed under pressure. Our Meatrol ME440 Three Phase Energy Logger uses flexible Rogowski coils and non-invasive voltage clamps, allowing electrical measurements without power interruptions. Only specific thickness measurements may require brief shutdowns for safety reasons.

We combine OPTI Engineering's decades of industrial expertise with cutting-edge measurement technology. Our team includes certified measurement professionals, we use state-of-the-art equipment (VPFlowScope M, ultrasonic flow meters, precision thickness gauges), and we provide comprehensive system analysis rather than just point measurements. Our instant quote system provides transparent pricing upfront.

Our compressed air audit service uses advanced VPFlowScope M equipment to measure air flow, identify leaks, and optimize your compressed air system for maximum efficiency and energy savings. We analyze pressure drops, consumption patterns, and equipment performance to provide detailed recommendations for reducing energy costs and improving system reliability. Our comprehensive audit includes leak detection, flow measurement, and energy consumption analysis.

Our water audit process involves ultrasonic flow measurement to analyze water consumption patterns, detect leaks, and provide recommendations for water conservation and cost reduction. We use non-invasive ultrasonic flow meters to measure water usage without disrupting operations, identify inefficiencies, and recommend optimization strategies that can reduce water costs by up to 30% while improving system efficiency.

We use state-of-the-art ultrasonic leak detection equipment to identify gas and liquid leaks in industrial systems. Our equipment can detect leaks as small as 0.1 CFM and provides accurate quantification of leak rates. We also use thermal imaging cameras and pressure testing equipment to ensure comprehensive leak detection across all types of industrial systems.

Yes, our ultrasonic flow meters can measure flow in pipes made of steel, copper, plastic, concrete, and other materials. We can measure flow rates from 0.1 to 50,000 GPM in pipes ranging from 0.5 inches to 200 inches in diameter. Our equipment works on both pressurized and gravity-fed systems, making it suitable for virtually any industrial application.

Flow verification focuses on measuring and validating flow rates at specific points in your system, while a system audit provides comprehensive analysis of your entire system including flow rates, pressure drops, energy consumption, efficiency, and optimization opportunities. Our system audits include flow verification as one component of a complete analysis that identifies cost savings and efficiency improvements.

Yes, we offer rental services for ultrasonic flow meters, thermal mass flow meters, thickness gauges, and power quality analyzers. Our rental equipment comes with full training, technical support, and calibration certificates. This is ideal for short-term projects, testing, or when you need specialized equipment for specific measurements without the capital investment.

We serve a wide range of industries including manufacturing, mining, power generation, chemical processing, food and beverage, pharmaceuticals, water treatment, HVAC, and automotive. Our measurement services are applicable to any industry that uses compressed air, water, gas, or electrical systems, and we have extensive experience across all major industrial sectors in South Africa.

Our energy audit measurements achieve IEC62053-22 Class 0.5 accuracy for electrical measurements, which is the highest accuracy class for energy meters. We use calibrated equipment that meets international standards and provide detailed accuracy reports with every measurement. Our energy audits typically identify 15-30% energy savings opportunities in industrial facilities.

Our comprehensive measurement reports include detailed measurement data with timestamps, system performance analysis, energy consumption calculations, leak detection results, efficiency recommendations, and optimization suggestions. Reports are delivered within 5 business days and include photographic documentation, data charts, cost-benefit analysis, and actionable recommendations for system improvements with projected ROI calculations.
