Denergy Jiemet (Beijing) Technology Co., Ltd. was founded in Zhongguancun Science and Technology Park, Beijing, and is located in Gu'an Development Zone, adjacent to Beijing Daxing International Airport and within the Xiong'an New Area economic circle. Since its establishment in 2009, we have adhered to the business philosophy of "returning to the essence and creating good watches", fully utilizing Beijing's talent advantages and investing long-term in product development. In 2013, a fully waterproof shell was launched, which solved the technical problem of glue waterproofing and non moisture proofing in the industry. And it has been applied to the company's full range of small caliber products, bringing a new solution for harsh installation environments in rural areas. In 2014, DTU IoT devices were launched, successfully solving the problem of upgrading wireless transmission functions for various products. In 2015, the "Internet of Things Water Meter" was launched, which was one of the first IoT water meters to be launched and sold in China. In 2017, the "Bluetooth smart water meter" was launched, ushering in the "Bluetooth era" of smart water meters! The Bluetooth smart water meter combines "smartphones" with "smart water meters", combining the advantages of card meters and remote meters, and does not require "water sales points", "toll collectors", or "meter readers". Since its launch, it has been widely recognized by customers. In 2019, the "Bluetooth NB Water Meter" was launched, achieving a significant breakthrough in overcoming signal blind spots and redefining NB water meters. Bluetooth NB water meter combines the advantages of both Bluetooth and NB water meters, with dual channel transmission between mobile phones and NB. Bluetooth and NB water meters can form a network and share the NB channel, successfully overcoming the problem of signal blind spots! In addition, DeNeng has a full range of IC card smart water meters, remote transmission water meters, large-diameter water meters, as well as flow meters, heat meters, etc., which can tailor high-quality products and solutions for customers. Having excellent technology alone is far from enough to make a smart water meter work stably for more than 6 years. To this end, DeNeng continues to invest in factory construction and manufacturing, and continuously improves production processes to enhance the product's fault free service life and reliability. We have successively invested in multiple SMT production lines, wave soldering, wax dipping machines, fully automatic screw machines, large-diameter flow tables, environmental testing chambers and other production and inspection equipment, greatly reducing the uncontrollability in production. 'Making customers proud of DeNeng' is the work pursuit of DeNeng people, 'we are all fighters' is the identity recognition of DeNeng people,' value driven, industry chain cooperation and win-win 'is DeNeng's development model, and' continuous improvement and stable operation 'is DeNeng's work style. De Neng Instrument, not just for the first time!
