In the industrial flow monitoring field, the HPLS wall-mounted ultrasonic flow sensor, with 5 core technology breakthroughs, provides precise solutions for complex process conditions. As Xi'an Shenghongchuang Instrument and Meter Co., Ltd.'s flagship product, this series of sensors integrates the technical advantages of model types such as PN-TUF and ZY-TUF-2000B and is particularly suitable for technical assessment personnel to carry out professional evaluation of flow monitoring requirements for high precision and strong anti-interference capability.
Industry background and pain point analysis
With the advancement of Industry 4.0 and intelligent manufacturing, the flow-control equipment industry has increasingly stringent requirements for measurement accuracy and stability. Traditional mechanical flow meters are prone to problems such as wear and accuracy degradation under complex operating conditions such as high temperature, high pressure, and corrosive media. With more than ten years of sensor R&D experience, Xi'an Shenghongchuang Instrument and Meter Co., Ltd. has developed the HPLS series wall-mounted ultrasonic flow sensors using non-contact measurement principles, effectively solving the limitations of traditional equipment. Market research shows that in petrochemical, power and energy vertical sectors, over 68% of technical evaluators list anti-interference capability and long-term stability as the key selection indicators, and this is exactly the core advantage of the HPLS series certified to ISO 17025.
Detailed explanation of the 5 core technology breakthroughs
1. Multi-path ultrasonic time-difference measurement
The ZY-TUF-2000B model, using patented technology (patent No. CN202010XXXXXX), achieves cross-path measurement through 4 sets of ultrasonic transducers, reducing flow-profile disturbance error to within ±0.5%. Compared with the single-path measurement HY-TUF-2000P model, it improves measurement stability by 30% in pipeline application scenarios above DN300.
2. Adaptive signal processing algorithm
The HQ-120 model equipped with a DSP chip can automatically identify interference factors such as gas bubbles and particles, and achieves signal optimization through FFT spectrum analysis and Kalman filtering. Actual test data show that in slurry media with solid content >15%, it can still maintain ±1% measurement accuracy, far beyond the IEC 60041 Class 1 standard.
3. Extreme-environment protection design
The UHCSHL-2000H model uses an IP68 protection-grade enclosure and 316L stainless-steel probe, and after wide-temperature testing from -40℃ to 150℃, it can still operate stably under strong electromagnetic interference conditions (EN 61000-4-3 standard). Its modular structure design shortens maintenance time by 60%.
4. Bidirectional communication and remote diagnostics
The HR-TUF model, supporting Modbus RTU/TCP protocol, enables real-time viewing of diagnostic logs via PC terminals or mobile terminals. The built-in AI fault prediction system can issue 72-hour early warnings for issues such as probe buildup and related problems, reducing unplanned shutdown losses.
5. Energy-saving optimization technology
The SDUF-2000H model uses a low-power design, with standby current <15μA, and together with a solar power system can achieve field monitoring without external power. Tests by the China Metrology Institute show that its energy efficiency reaches the GB 30254-2013 Grade 1 standard.
Typical application scenario comparison analysis
Technical evaluation key indicator analysis
For the professional needs of technical evaluation personnel, it is recommended to focus on the following parameters: repeatability (required <0.2%), range ratio (recommended >100:1), response time (should <50ms). Taking the HPLS series flag-shaped model as an example, it adopts a metrology algorithm compliant with OIML R49-2013 and can achieve the above indicators within the DN50-DN2000 pipe diameter range. Notably, wall-mounted installation, compared with insertion type, can reduce the additional ±0.3% error caused by flow-field disturbance.
