Established in 2003 and specialized in R&D and production of heat metering products, Weihai Zhenyu Intelligence & technology Co., Ltd is the first company in weihai city listed and traded in the QILU OTC with the stock code 100109. As a member company of China Association of Heat Meter and China Association of Urban Heating, it is also one of the earliest domestic manufactures developing and producing heat meters.
Adhering to the "science and technology as guide, innovation promote development, quality tree brand, integrity win market" business philosophy and taking "make high quality products, be responsible for society, allow user rest assured" as the enterprise purpose, the company always puts product technology research and development at the first place and takes product quality improvement as unremitting pursuit. The company has successively carried out technical cooperation with National Ministry of Ordnance Industry 208, Harbin Institute of Technology, Zhejiang University and many other units and provided strong technical support for product innovation and upgrading. In recent years, against the problems the heating enterprises encountered in heating metering, the company continually improves and enhances the product technical performance and makes the ZY heat metering products with much wider applicability.
ZY no reflection plate ultrasonic heat meter and split mechanical heat meter are products of the company independent R&D and innovation and have obtained national patent. As upgraded product of traditional ultrasonic heat meter, ZY ultrasonic heat meter has changed the traditional ultrasonic heat meter structure and improves the measurement accuracy and stability. ZY split mechanical heat meter is the only product with split structure of domestic similar products.
With the registered capital of 40 million, the company has established a production base in the new industry district in Weihai City, which has 5000 square meters of existing standard production workshop and all kinds of production and testing facilities and complete equipments and has the production capability of DN20-200 ultrasonic heat meter and split mechanical heat meter with an annual output of 800 thousand to 1 million pieces.
