Multifunctional modular technology: This module integrates many proprietary technologies, including 1, low-distortion signal amplification 2, automatic signal gain control 3, high-speed A/D conversion 4, digital signal processing 5, high-precision and high-resolution transmission time and time difference measurement, etc.
Micro-power measurement technology: the design of micro-power ultrasonic flow measurement circuit, combined with micro-power high-sensitivity sensor, greatly reduces the power consumption of ultrasonic flowmeter (power consumption
High-precision time detection technology: Tangshan Zhonghui Instrument Co., Ltd. adopts the unique time measurement technology of Zhonghui, and the time resolution is 25ps, reaching the international leading level. Especially for the measurement of small aperture and low flow rate, it has more practical significance.
High-performance ultrasonic transducer technology: In 2009, he undertook the research on "Key Technology of High-performance ultrasonic transducer" in the 863 key project "Process Control Flow Sensor and System" of the Ministry of Science and Technology, and applied the scientific research results to Zhonghui products.
Digital signal processing (DSP) technology: The application of DSP technology in ultrasonic flow transmitter plays a vital role in improving the accuracy, repeatability, anti-interference ability and applicability of the instrument.
Unreal flow calibration technology: the real flow calibration cost of large-caliber flow sensor is high, and it is almost difficult to achieve real flow calibration for flow sensor larger than DN2000. Unreal flow calibration method can solve the accuracy problem of ultrasonic flow sensor in large-aperture flow measurement.
Multi-channel ultrasonic measurement technology: multi-channel structure design, double-section measurement, in complex flow conditions, to maximize the measurement accuracy.
IP68 protection technology: The IP68 design of each unit of the instrument constitutes the whole IP68 structure, ensuring the all-weather safe operation of the product.
High-temperature ultrasonic flow sensor technology: The development of high-temperature ultrasonic flow sensor of Tangshan Zhonghui Instrument Co., Ltd. not only enables the sensor to operate normally at the high temperature of 150℃, but also greatly improves the signal strength and pressure resistance, effectively broadens the measurement range of ultrasonic flowmeter and meets the needs of customers to a greater extent.
Drilling technology under pressure: a patented technology developed for installing plug-in ultrasonic sensors. The patented tool developed by using this technology not only has the characteristics of small volume and saving installation space, but also has the functions of automatically cooling the drill bit and removing iron filings when drilling, which makes the installation of the plug-in ultrasonic sensor easier.
Plug-in ultrasonic flow measurement technology: This technology can be divided into plug-in technology and double plug-in technology. The development of plug-in ultrasonic flow sensor, on the one hand, realizes on-line installation with pressure and avoids economic losses caused by shutdown; On the other hand, the stability and reliability of long-term measurement of the external clamp ultrasonic flowmeter are improved.
