From March 27 to March 29, 2012, the 3-day 2012 China International Metering Conference was held in Hangzhou New Century Grand Hotel. The conference was attended by many authoritative certification agencies and well-known manufacturers from home and abroad. Xi Ke, general manager of our company, gave a speech at the conference entitled "Leading Metering Technology and Products from the Perspective of Market Operation and Feedback", which won warm applause and recognition from the audience. Afterwards, many domestic and foreign institutions had in-depth discussions with Xi, and came to the on-site booth to watch and inquire about our water, electricity, gas and heat metering products. After listening to the on-site product explanation, many customers expressed their urgent intention to cooperate.
