Shenzhen city built constant monitoring and control Limited by Share Ltd   

China Shenzhen Jianheng company founded in 1993, is a professional research and development of new ultrasonic flow meter and flow calibration technology of high-tech enterprises, more than a decade to build constant has always insisted on taking the professional route, in the flowmeter and calibration technology made many achievements, built constant has made 26 national patents, including patents 14, 8 patents for utility models, the appearance of two patents, overseas PCT patent 2. Its products have been recognized and used by the national aerospace and other cutting-edge fields, the export of foreign built constant ultrasonic flowmeter has been recognized by the u.s.. In China, a constant flow calibration device has been successfully applied to the calibration system of the rocket launching attitude control valve and the fuel consumption verification system of the fighter aircraft. China and the industry has achieved a number of first: The first has a high dynamic response, low flow, and other special applications, Kai enterprises closed flow measurement and calibration technology, to fill gaps in the world. The Chinese first entered the field of aerospace high response flow calibration device manufacturers The first use of Chinese piston volume tube construction flow calibration device, to achieve three times the scale of enterprise; The first China ultrasonic flowmeter manufacturers domestic own brand products exported to Europe and the United States; The first use of Chinese flow calibration device of tank valve school school enterprise The Chinese first built circumfluent flow calibration apparatus of enterprise; China first by their own core technology and patents, to become the American well-known brand design and production of ultrasonic flowmeter and matched sensors manufacturers; The China first applies PDA in ultrasonic flowmeter manufacturers; The first Chinese Bluetooth technology will be applied to the ultrasonic flowmeter manufacturers; The Chinese first entered the field of aerospace high response piston volume tube manufacturer;
