Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Precision Fluid Measurement: Equipped with ultrasonic technology, the DLTEREN flowmeter provides accurate flow rate measurements (±0.2%–0.5%) and real-time velocity readings (m/s) for water, oil, and other liquids.
  • Non-Invasive & Versatile: Designed for clamp-on ultrasonic measurement, it avoids direct fluid contact, ensuring compatibility with corrosive or high-pressure fluids while maintaining ease of installation.

Key features

  • 1. Non-Invasive Ultrasonic Technology

    • With ultrasonic measurement technology, you can achieve precise fluid flow readings without disrupting pipelines or requiring direct contact with the fluid. This method is ideal for corrosive or high-pressure environments compared to traditional intrusive sensors.*

  • 2. Ergonomic Design with Intuitive Controls

    • With an ergonomic, handheld design featuring a digital display and numeric keypad, you can easily navigate settings and monitor real-time data (flow rate, velocity) in the field. This contrasts with bulkier, less user-friendly models.*

  • 3. Industry-Leading Accuracy

    • With ±0.2% accuracy, you can ensure highly reliable measurements for critical applications, outperforming standard models with ±1% accuracy or higher.*

  • 4. Versatile Portability and Power Efficiency

    • With a battery-powered, compact design, you can deploy the flowmeter in remote or mobile settings, unlike stationary or mains-dependent alternatives.*

  • 5. Multi-Media Compatibility

    • With support for water, oil, and other liquids, you can adapt to diverse industrial or commercial scenarios, exceeding single-media flowmeters in flexibility.*

⭐ Customer Reviews and Testimonials

Authentic User Feedback

🔧 Industrial Maintenance Engineer Review

⭐⭐⭐⭐⭐ James Carter - Industrial Maintenance Engineer
"Purchased the DLTEREN Pro Model in February 2025 for pipeline monitoring at a chemical processing plant. After 7 months of near-daily use, I can confidently say this is the most reliable portable flowmeter I’ve worked with. The ±0.2% accuracy is not marketing fluff—it matches our fixed inline sensors within tolerance. The non-invasive clamp-on design has saved us hours in downtime, especially when checking high-pressure lines without shutdowns. RS232 integration with our data logger was seamless thanks to DLTEREN’s custom protocol support."

🌾 Agricultural Irrigation Specialist Review

⭐⭐⭐⭐☆ Sofia Ramirez - Agricultural Consultant
"I bought the Advanced Model in October 2024 to monitor irrigation efficiency across multiple farms. It’s been invaluable for identifying leaks and optimizing water distribution. The 12-hour battery life is solid—I’ve used it all day in remote fields without needing a recharge. The digital display is bright and readable even in direct sunlight. My only minor gripe is that the manual could be clearer on unit conversion (switching from m³/h to L/min), but once set, it works flawlessly. Durable enough to survive dust, rain, and being dropped more than once!"

⚙️ Oil Refinery Technician Review

⭐⭐⭐⭐⭐ Amir Hassan - Oil Refinery Technician
"We deployed three DLTEREN Pro Models in January 2025 for spot-checking crude oil flow in aging pipelines. The rugged orange casing stands out visually on-site, which safety loves, and the wrist strap prevents drops in tight spaces. Real-time velocity and flow rate readings let us catch anomalies before they become issues. Calibration service was prompt and compliant with ISO standards—critical for audit readiness. This device outperforms older mechanical meters tenfold in both precision and safety."

🏗️ Construction Site Supervisor Review

⭐⭐⭐⭐⭐ Elena Peterson - Site Supervisor, Civil Engineering Firm
"As someone managing multiple construction sites, portability and durability are non-negotiable. The Base Model, purchased in May 2024, has been used weekly for dewatering pump checks and concrete curing water monitoring. It’s lightweight, easy to operate, and survives being tossed in a truck bed daily. The ±0.5% accuracy is more than sufficient for our needs, and the 8-hour battery covers a full shift. For the price, it’s an outstanding tool that’s already paid for itself in time saved."

Purchase Date: May 2024 | Usage Period: 5 months

💡 Field Service Engineer Review

⭐⭐⭐⭐☆ David Lin - Field Service Engineer, Environmental Monitoring
"I’ve been using the DLTEREN Advanced Model since November 2024 for environmental compliance checks on wastewater outflows. Its compatibility with various pipe materials and fluids makes it ideal for unpredictable field conditions. I appreciate the Modbus-enabled RS232 output—it syncs perfectly with our SCADA test rig. The ergonomic grip reduces hand fatigue during long surveys. One suggestion: include a protective case by default. Otherwise, performance is excellent, and customer support responded quickly when I needed help with configuration."
