Clamp-on Ultrasonic Flowmeter
Approved by:CE, SIL-3, ATEX Explosion-proof certification
This portable ultrasonic flowmeter is a fully portable, clamp-on ultrasonic flowmeter, it combines high precision, mobility, and ease of use in one compact instrument.
Using advanced advanced clamp-on sensors and transit-time technology, it measures liquid flow from outside the pipe—no cutting, no pressure loss, no downtime. Its lightweight handheld design, built-in rechargeable battery, and clear LCD make it perfect for on-site inspections, system commissioning, and flow verification. And it equipped with a data logger, Modbus connectivity, and a thermal printer, it delivers complete measurement and documentation power in the palm of your hand.
Its smart interface, wide pipe range (DN15–DN6000), and strong anti-interference design ensure dependable readings in water, chemical, or energy systems, it gives engineers a dependable, easy-to-use solution for accurate, non-contact flow measurement anywhere.
-
Non-intrusive clamp-on measurement – Measures from outside the pipe, so you don’t stop production and you don’t open the line.
-
Wide pipe range (DN15–DN6000) – One portable meter can cover small process lines and large mains, so you don’t have to carry different instruments.
-
High measuring performance (±1% accuracy, 0.5% linearity, 0.2% repeatability) – Gives stable, trustworthy readings, so you can use the data for real decisions, not just “reference.”
-
Built-in rechargeable battery (≈20 h) – Works a full day in the field on one charge, so you can finish site work without hunting for power.
-
Built-in thermal printer – Prints instant or timed measurement reports on site, so you can hand results to the client immediately.
-
Built-in data logger and PC upload – Stores multiple sets of measurement data and can send them to a computer, so you keep a traceable record.
-
Multiple transducer options (standard, medium, large, high-temp) – You can match the sensor to pipe size and liquid temperature, so measurement stays reliable.
-
Strong anti-interference design – Balanced low-voltage multi-pulse circuit resists inverter noise, so it still measures in harsh industrial environments.
-
Rich I/O (4–20 mA, frequency/pulse, RS-485, buzzer/alarm) – Can output to external systems or be used in semi-temporary monitoring, so it’s more than a “one-off” tester.
-
Rugged portable case – Supplied in a protective carrying case, so it can travel to different sites and stay intact.
