Located in Tangshan, Hebei province, Huizhong Instrumentation Co., Ltd. has grown to its official listing in the field of ultrasonic flow measurement in China (stock code: 300371, securities abbreviation: Huizhong Stock). Founded in 1994, Huizhong owns 94000㎡ floor areas and a provincial engineering laboratory, which is also a provincial high-tech and software enterprise. In addition, the testing and calibration laboratory of Huizhong has been approved by China National Accreditation Service for Conformity Assessment (CNAS). 2 wholly-owned subsidiaries of Huizhong: Huizhong Technology Tangshan Co., Ltd. and Huizhong Instrumentation (Hong Kong) Co., Ltd.

Through more than 30 years of unremitting efforts, Huizhong has become one of the leading R&D and manufacturing base companies in China specializing in Ultrasonic Water Meters, Ultrasonic Heat Meters, Ultrasonic Flowmeters, and Ultrasonic Metering Systems, which owns the largest product series, the strongest technology strength, and the widest calibration range (DN15-DN15000). The ultrasonic metering products have covered the production and life fields which from industry to civil, flow to heat, and China to the world.

Huizhong owns all the proprietary intellectual property rights of all products and nearly 100 patents, covering the range of applications from terminal data acquisition to system R&D integration. In addition, Huizhong has also participated in the formulation of industry and national standards, such as " Ultrasonic Flowmeter for Water Supply and Drainage Application (operating on the principle of propagation velocity difference)", "Heat Meter", "Verification Regulation of Ultrasonic Flowmeters". In 2008, Huizhong participated in the research of “Flow Sensor and System for Industrial Process Control”—the 863 Program assigned by the Ministry of Science and Technology. The research-derived achievements are not only constructive to the independent R&D and industrialization of advanced sensors in China, but also marks Huizhong's technology has reached the international advanced level.

As a technology-based innovative enterprise, Huizhong has chosen the technology-based development strategy at the beginning of its establishment. The company not only has mastered the core technology of ultrasonic flow measurement, but also built a powerful intelligent manufacturing platform for ultrasonic flow measurement meters. Based on big data, Huizhong has realized intelligent orders, flexible customization of products, product lifecycle management, intelligent storage, cloud services, etc., which can meet customers' needs in comprehensive and multiple perspectives.

Combining localization and internationalization, Huizhong will actively play its own advantages to build a professional, efficient and intelligent global enterprise.
