Thermal gas mass flowmeter
Flow measurement be application for
1 Gas in industrial pipelines
2 Air during gas combustion
3 Flue gas out of chimneys
4 Waterfall gas during water treatment
5 Gas and compressed air during production of cement, cigarette and glass
6 Natural gas, coal gas, liquefied gas, flare gas and hydrogen gas etc.
7 Flow measurement of trapped gas in steelworks
This 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.
