I. Overview: 
 Level transmitter is the introduction of U.S. NoVa's advanced circuit technology diffusion silicon pressure Sensors developed with, and it applied fine silicon and silicon composite corrosion process two world cutting-edge technology, is a high-quality hydrostatic level measurement instrument widely used in petroleum, chemical, metallurgy, environmental protection, food, water, urban water supply, oil and other liquid level measurement industry. 
 Level transmitter for excellent quality, a variety of ways to facilitate the installation process on-site installation, special occasions can be specially designed. Meet some of China's industrial automation and high-precision measurement of industry level instrumentation needs.
