Bonvoisin Handheld Ultrasonic Flow Meter
Best for: Small to mid-size pipelines handling seawater, alcohol, and industrial liquids without shutting down processes. The Bonvoisin unit uses S1+M2 sensors for straightforward pipe clamping and quick setup. It supports on-pipe data logging and real-time display, with a built-in logger that records up to 2000 data points. This makes it suitable for periodical compliance checks and process monitoring where uptime is critical. The design favors environments where pipe access is limited and non-destructive measurement is essential.
Why selected: It emphasizes nonstop operation by avoiding pipeline destruction during measurement. The internal data logger and real-time readouts provide actionable insights for operators who need ongoing visibility into flow trends. Units are configurable in liters or gallons to match regional reporting requirements.
Caution: If larger diameters (L2 DN300–6000mm) are needed, additional sensor options may be required; confirm compatibility with your pipe size before purchase.
Ultrasonic Flow Meter Tuf-2000b (EnSyuSuMa)
Best for: Applications needing multiple signal options and robust measurement across liquids like water, sea water, sewage, and alcohol. It ships with TS-2 and TM-1 transducers, a dedicated host, and multiple output options (4-20mA, octal pulse, relay). The generally stable performance makes it suitable for continuous monitoring in municipal and industrial settings where reliable data outputs are critical for control systems.
Why selected: The array of signal outputs supports integration with existing SCADA or data logging systems. The device emphasizes non-contact measurement and a broad compatibility profile, reducing the risk of pipe damage during installation.
Caution: Ensure software access is available for data download; some users may require additional access tools to view historical data off the machine.
Ultrasonic Flow Meter With Small & Medium Transducers (ValueStoreUS)
Best for: Facilities requiring a wide operating temperature range and compatibility with many pipe materials. The unit supports measuring flow in both plastic and metallic pipes and tolerates liquids from water to fuels and fuels-related products. The high-temperature transducers extend usable conditions well beyond standard water-only meters, making it suitable for chemical plants and energy facilities.
Why selected: Its broad liquid compatibility and high-temperature tolerance make it versatile for mixed-liquids environments. The device is designed to measure across a large range of pipe materials, reducing the need for multiple meters in the same plant.
Caution: Accuracy remains strong but verify the installation method aligns with the specific pipe material to maintain optimal performance.
Ultrasonic Flow Meter TUF-2000B For Liquid Control (HYYKJ-US)
Best for: Outdoor or harsh environments where IP67/68 protection adds value. The device supports multiple liquid types and offers non-contact measurement with durable construction. It is suited for water supply, chemical processing, and energy sectors where long-term reliability is important.
Why selected: Bi-directional metering allows monitoring flow in both directions without reconfiguration, which is helpful for systems with return lines or recirculation. The rugged shell contributes to extended service life in challenging installations.
Caution: While robust, ensure adequate mounting space and consider the need for power and data interfaces in outdoor locations, especially in remote plants.
GEHPYYDS Handheld Ultrasonic Flow Meter
Best for: Large-diameter pipes and liquids where non-contact measurement protects structural integrity. The GEHPYYDS model emphasizes a non-contact method, with multiple sensor options and straightforward pipe clamp-on installation. It is a strong fit for process industries requiring minimal downtime during retrofits or upgrades.
Why selected: The ability to clamp onto the outer wall without pipe cutting makes it ideal for retrofit projects. The sensors simplify installation and reduce the need for pipe alterations while providing reliable flow data.
Caution: Confirm sensor compatibility for very large DN ranges, as some configurations may require additional support hardware for secure mounting.
Buying Guide: Key Considerations for Ultrasonic Strap-On Flow Meters
- Pipe size and transducer range: Match pipe DN/diameter with available sensor families (DN15–DN6000mm). Ensure the transducer range covers your largest and smallest pipes.
- Liquids and temperature handling: Check liquid compatibility and maximum temperature. Some meters handle seawater, alcohol, oil, and sewage; others emphasize high-temperature transducers.
- Measurement method: Non-contact clamp-on measurement preserves pipes and enables retrofits without shutdowns. Consider whether bidirectional measurement is needed for recirculating systems.
- Accuracy and stability: Look for ±1% accuracy, 0.2–0.5% repeatability, and 0.5% linearity. This informs reliable process control and billing/traceability.
- Outputs and integration: 4-20mA, pulse, relay, and RS-485 options support SCADA, data logging, and telemetry. Ensure compatibility with your control system.
- Data logging and software access: Many units include internal data loggers (2,000+ records) and software for historical analysis. Verify file formats and export options.
- Environmental protection: IP67/68 ratings are essential for outdoor installations. Confirm the shell material and sealing meet your environment’s exposure level.
- Installation and maintenance: Clamp-on sensors should be easy to install on accessible pipe sections. Consider maintenance intervals and battery life for handheld units.
FAQ
- Do these meters require pipe cutting? No. They use non-contact clamp-on transducers attached to the pipe exterior.
- Can they handle seawater and alcohol? Yes, several models are specified for seawater, alcohol, and other liquids, depending on the transducers and materials.
- What outputs are commonly available? Common options include 4-20mA, pulse (octal), and relay outputs for control and logging.
- Is data export supported? Many units offer internal data logging and software for downloading historical measurements.
- What maintenance is needed? Routine checks of sensors and seals are advised; non-contact meters typically require less inline maintenance than insertion types.
- How do I choose the right size? Determine the largest pipe diameter in your system and confirm sensor compatibility; larger systems may need multiple transducer sets or specialized options.
