Product Overview

This HFU series ultrasonic flow meter is an industrial-grade time-of-flight (transit-time) ultrasonic flow meter. Compared with other ultrasonic flow meters on the market, it features high response speed, low power consumption, and high stability.The product inherits the proprietary TGA technology independently developed by our company, and is widely used in industries such as building HVAC systems, thermal power plants, oil & gas and chemical industries, and water treatment. It can be applied in three installation types: clamp-on type, insertion type, and inline (pipe section) type.

Product Features & Advantages

High Accuracy & Fast Measurement: A time-of-flight ultrasonic flow meter with a measurement speed of up to more than 300 times per second, ensuring strict control of accuracy within 1.0%.
Powerful Signal Processing: Equipped with the latest industrial-grade FPGA chip with 700,000 logic gates, significantly improving signal sampling frequency and bubble resistance. Time measurement accuracy can reach tens of picoseconds (ps).
Proprietary Core Technology: The independently developed TGA technology enables more complex logic processing and computation, achieving more accurate and faster measurement performance.
Excellent Overall Performance: Features high response speed, low power consumption, and high stability.
Bubble & Impurity Resistance: Capable of handling intermittent air bubbles or impurities for up to 5 seconds without affecting measurement stability.
Easy Installation: Simple installation and easy operation. Installation can be completed without pipe cutting, and without water supply interruption or production shutdown.
Durable Metal Housing: Full metal enclosure with high protection level, excellent electrical and thermal conductivity, strong durability, and outstanding impact resistance.
