Our products warmly welcomed by customers in the worldwide. With years of expertise and a passion for innovation, we are dedicated to transforming how you manage your utility meters.   What We Offer: Water Meter Testing Equipment Gas Meter Testing Equipment Various Flow Meter Testing Equipment Customization Options Training and Support Future-Ready Technology   Who Do We Serve We offering comprehensive calibration solutions for a diversity of clients in the Water Works and Gas Works Industry, both nationally and internationally such as: Municipal water and gas companies. State or Government owned Water and Gas Commissions. Water Meter and Gas Meter Testing & Verification companies. Private industries and companies in the Water Works or Gas Works business. We also provide tailor-made solutions for clients on flow meter industry.   Our Team. As experts in the field of metrology, we place a strong emphasis on both product research and development, as well as exceptional after-sales support. Our primary goal is to deliver products that meet the highest standards, reflecting our dedication to precision and quality. With a focus on innovation and customer satisfaction, we stand by our promise to offer top-notch products coupled with reliable after-sales assistance. For our R&D team, we have: ● One professor-level senior engineer and one senior engineer ● Over ten software engineers, hardware engineers, structural design engineers. ● Over twenty production and skilled assembly workers in the company. ● Besides, we have kept good relations of cooperation with the relevant research institutes, which ensure our company’s products and technology keep a leading position in this industry.     Our Innovation     1. Venturi Sonic Nozzle Our company independently designs and manufactures the Venturi sonic nozzle in accordance with the requirements of ISO9300-2005 (E) "Measurement of gas flow using critical flow Venturi nozzles" and JJF1240-2010 "Calibration Specification for Standard Devices of Gas Flow using Critical Flow Venturi Nozzle Method. "   The relative expanded uncertainty (Urel) of the nozzle discharge coefficient is 0. 2% (k=2), as stated in the calibration certificate issued by a metrological verification institution at the provincial level or higher.   Venturi sonic nozzle is characterized by simple structure, stable performance, high accuracy, easy maintenance, long verification circle( 5 years ), no moving Parts etc.     2. Dynamic Image Processor(apply to gas meter test bench) High efficiency: Dynamic image processor not only recognize gas meter counter but also count number and count time automatically. Thus，it means shorten run empty time before test gas meter. Especially for Qmax and Qmin, which greatly enhance efficiency. If we compare with optoelectronic sampling, dynamic image processor can enhance 20%-40% efficiency.   Long distance test: dynamic image processor has high pixel, the distance between the camera and the gas meter being inspected can be extended to 7cm, making it convenient for the removal, installation, and wiring of IC card gas meter batteries. High collection rate: Dynamic image processor has above 99% success rate which collect gas meter signal. It overcomes manual adjustment, difficult to focusing, even collect signal unsteadily after adjustment     3. Dynamic image processor(apply to water meter test bench) We usually use human eye recognition and infrared laser on the test bench to catch the information of the water meter, which has lot of shortcomings, thus we develop dynamic image processor to get the water meter information, With the following advantages that warmly welcome by our clients.   1. Efficient detection, 2. Verification function 3. Movement installation error correction function. 4. Meter Number Entry   Our Glorious History As a professional manufacturer specializing in gas meters, water meters, and various flow measurement testing devices, and being a key player in the industry, our company has actively participated in the drafting of several national standards and regulations in the People's Republic of China.   We have contributed to the formulation of the "Calibration Device for Water Meters JJG1113-2015, " a national metrology calibration regulation.   The "Bell Prover Gas Flow Standard Device JB/T 12961-2016, " a mechanical industry standard.   The "Calibration Specification for Positive Displacement Piston Flow Standard Device JJF1586-2016, " a national metrology technical specification.   Simultaneously, our company's dedication to research and development has gained remarkable achievements. Our "High-Precision Bell Prover Gas Flow Standard Device" was honored with the Zhejiang Province Science and Technology Award (Third Prize).   Furthermore, our "Piston-Type Gas Flow Calibrator Based on Zero-Balance Adjustment Principle" received the Zhejiang Province Quality Technology Supervision Technological Innovation Award (First Prize).   These accolades underscore our company's prowess in professional technical research and manufacturing capabilities.     Our Factory We have a strong transportation advantage with easy access, being situated near Shanghai and Ningbo.
