Recently, the Chongqing Municipal Science and Technology Commission Organization Acceptance Team accepted and accepted the municipal high-tech special project "High-performance electromagnetic flowmeter" undertaken by Chongqing Chuanyi Automation Co., Ltd., and was approved to pass.
The project studied electrode sealing, detection of low-conductivity media (such as pulp), detection and processing of weak signals in high-voltage environments, design of high-performance sensors based on non-uniform magnetic field distribution, verification of magnetic field distribution tests, and precision of microvolt-level sensing signals. Measurement and interference suppression, multi-frequency excitation of slurry electromagnetic flowmeters, noise filtering based on digital signal processing, signal extraction, temperature compensation, and error correction techniques, applied for 5 patents (including 2 invention patents), and obtained 2 authorizations Obtain 1 software copyright. Developed three types of products: high-precision electromagnetic flowmeters, slurry-type electromagnetic flowmeters, and capacitive electromagnetic flowmeters, and developed a corporate standard for high-performance electromagnetic flowmeters. The high-precision electromagnetic flowmeter passed the type test of the China Institute of Metrology, and the slurry-type electromagnetic flowmeter and the capacitive electromagnetic flowmeter passed the type test of the 18th measurement and test center of the machinery industry. It has built a demonstration base for the production and manufacture of high-performance electromagnetic flowmeters and has an annual production capacity of 7,000 sets. The project products have been widely used in metallurgical, chemical, water, and papermaking projects.
