Beijing Huamai new technology Co., Ltd. is a professional designer & manufacturer of instrumentation and automation meter since 1995, also a "high-tech enterprises" located in state-level industrial development zones, Certificate No: 0130273F. The company has developed the first generation of vortex flow meter, Engineer Han is the creator of this type flow meter. Under the leadership of Engineer Han (president), the company towards to bring products to promote application of engineering and technology mutual development.
Our Flow Meter Development History:
Release thermal-vortex flow meter in early of 70s, Release stress, large-diameter plug-in vortex flow meter in 80s, Release small-caliber, high temperature, corrosion-resistant, as well as two-wake vortex flow meter in 90s, Release Down hole ESP instrument in 2000. In recent years, due to the use of the latest microprocessor technology and modern digital signal processing, so that the vortex detection with a variety of intelligent functions which standard for the trend of vortex flow meter.
Main products are
Vortex Flow Meter, Vortex & Swirl Flowmeter;
Ultrasonic Flow Meter, Ultrasonic Level Meter,
