Product Introduction
The GTUF-300 Ultrasonic Flow Meter (Heat Meter) is a next-generation fixed, online integrated sensor developed by aggregating our cutting-edge ultrasonic measurement technologies. It boasts a sleek, compact design and outstanding precision. Equipped with a clear dot-matrix LCD display, it allows users to immediately check flow rate, temperature, and heat data in real time on-site.
In particular, by introducing advanced Digital Signal Processing (DSP) technology, it fundamentally blocks interference from impurities inside the pipe—such as rust, iron filings, and welding slag—perfectly eliminating the risk of malfunctions found in conventional flow meters. Capable of independent measurement up to 32 channels with a single device, it provides an optimal smart measurement solution even in complex, large-scale facility lines or open-channel environments, while offering exceptionally easy installation and maintenance.
Product Features
- Integrated Sensing of Flow, Temperature, and Heat: By connecting a single sensor line, it can simultaneously and precisely measure flow rate, temperature, and heat energy, lowering system configuration costs and efficiently saving installation space.
- Ultra-Fast DSP Signal Processing Technology: Equipped with a high-speed DSP processor, it shortens the system response time to less than 0.1 seconds, reacting instantly and accurately to subtle changes in flow.
- Powerful Digital Noise & Interference Rejection: Through advanced signal correlation technology and sophisticated filtering algorithms, it outputs stable data without frequency distortion, even under harsh conditions where sediment or air bubbles are present in the pipe.
- Ultra-Low Power & Long-Life Battery: Designed with ultra-low-power circuitry, it can operate continuously for at least 6 years using only its built-in backup battery without any external power source, even in demanding fields where power supply is difficult.
- Flexible Output & Industrial Communication Support: It natively supports self-powered 4-20mA analog output and OCT pulse signals for precise control, as well as standard industrial RS485 communication (Modbus RTU protocol), ensuring seamless integration with smart factory systems.
Applications
- Petrochemical & Harsh Chemical Process Lines: Real-time flow monitoring of chemical product transfer pipelines and precise flow management of high-viscosity oils and corrosive chemical liquids.
- Energy Buildings & Power Plant Facilities: Efficiency monitoring of large heat exchangers and factory cooling water circulation systems, and integrated precision control linking heating and cooling energy (applying the heat meter function).
- Water/Wastewater Treatment & Large Open Channel Control: Water purification plants operated by municipalities, dams, and open channel pipe management; intelligent water treatment measurement for partially filled or complex, large U-shaped conduits in connection with liquid level meters.
- Semiconductor & Secondary Battery Smart Manufacturing Processes: Micro-flow monitoring of ultrapure water (UPW) supply lines and utilization as standard equipment for high-precision chemical dosing and transfer control.
- Compatibility with Various Pipe Materials & Environments: Perfect adaptation to most metallic and non-metallic pipes—including stainless steel (STS), carbon steel, PVC, PPR, and concrete pipes—using either clamp-on or plug-in sensors.
