General Introduction
The advanced technique of Silver Automation Instruments has been introduced to produce this flow meter measuring gas mass flow. Traditional flow meters need to adapt temperature and pressure compensation for measurement of fluid mass flow, whereas this China Thermal Mass Flow meter can directly measure fluid mass flow without requiring temperature and pressure compensation. Its conspicuous features are as follows: direct trade settlement, no movable components, small pressure loss, wide range ratio, high accuracy, high reliability, simple installation and convenient operation. It is extensively used in the industries such as petroleum, chemical industry, medical industry, heat power plant and environmental protection etc.

Typical Applications
Flow measurement of gas in industrial pipelines
Flow measurement of air , used as gas combustion flow meter
Flow measurement of flue gas out of chimneys,
Flow measurement of waterfall gas during water treatment
Flow measurement of gas and compressed air during production of cement, cigarette, and glass,it is a kind of compressed air flow meter,
Flow measurement and used as natural gas flow meter, coal gas flow meter, liquefied gas flow meter (LPG gas flow ), flare gas and hydrogen gas etc.
Flow measurement of trapped gas in steelworks
