1. Excellent technology of Tangshan Huizhong Instrument Co., Ltd.

Micro power consumption large aperture measurement technology: under battery power supply conditions, it realizes the digitization of ultrasonic reception signals, effectively identifies interference signals and waveform jitter; Micro power consumption high-sensitivity sensor technology effectively improves the strength of ultrasonic signals, ensuring stable measurement under large aperture (DN300-DN1600) conditions. Multi functional modular technology: This module integrates multiple proprietary technologies, including 1 Low distortion signal amplification 2 Signal automatic gain control 3 High speed analog-to-digital conversion 4 Digital signal processing 5 High precision, high-resolution transmission time and time difference measurement, etc. Micro power measurement technology: The design of a micro power ultrasonic flow measurement circuit, combined with a micro power high-sensitivity sensor, greatly reduces the power consumption of the ultrasonic flow meter (power consumption<1mW), ultimately achieving a battery that can work continuously for more than 10 years. High precision time detection technology: Using Huizhongs unique time measurement technology, Tangshan Huizhong Instrument Co., Ltd. has a time resolution of 25ps, reaching the international leading level. Especially for small caliber and low flow velocity measurements, it has practical significance. High performance ultrasonic transducer technology: In 2009, we undertook the research on "Key Technologies of High performance Ultrasonic Transducers" in the National Science and Technology 863 Key Project "Process Control Flow Sensors and Systems", and applied the research results to H

uizhong products. Digital Signal Processing (DSP) technology: The use of DSP technology in ultrasonic flow converters plays a crucial role in improving the accuracy, repeatability, anti-interference ability, and applicability of instruments. Non real flow verification technology: The cost of real flow calibration for large-diameter flow sensors is relatively high, and it is almost difficult to achieve real flow calibration for flow sensors larger than DN2000. The use of non real flow calibration methods can solve the accuracy problem of ultrasonic flow sensors in large-diameter flow measurement. Multi channel ultrasonic measurement technology: Multi channel structural design, dual section measurement, can ensure maximum measurement accuracy under complex flow conditions. IP68 protection technology: The various units that make up the instrument are designed with IP68 to form an overall IP68 structure, ensuring the safe operation of the product 24/7. High temperature ultrasonic flow sensor technology: The development of high-temperature ultrasonic flow sensors by Tangshan Huizhong Instrument Co., Ltd. not only enables the sensor to operate normally at high temperatures of 150 ℃, but also significantly improves signal strength and pressure resistance, effectively expanding the measurement range of ultrasonic flow meters and meeting the needs of customers to a greater extent. Pressure drilling technology: a patented technology developed for the installation of plug-in ultrasonic sensors. The patented tool developed using this technology not only has the characteristics of small size and saving installation space, but also has the function of automatically cooling the drill bit and removing iron filings during the drilling pr
