Core technology

The breakthrough of the company in the field of capacitor digital sensor has filled the gap of the industry, and made up the shortcomings of the traditional sensors such as, low measurement precision, high environmental requirements and poor product stability. The operation of the capacitor digital sensor realized automatic calibration without the affection of temperature and medium changes. It provides reliable solutions for accurate measurement and assessment of fuel consumption of automobiles, aircrafts, ships, etc., and has been widely used in the management of safety operation of boilers and gas stations.
