Application site：flue gas pipeline measurement of ammonium molybdate production in a nonferrous industry. The combustion furnace produces a large amount of ammonia, which needs accurate measurement to facilitate the stable use of the subsequent treatment device and make the exhaust emission meet the standard.

Pipe diameter: DN500, flow rate: 2000nm3 / h, temperature: 80 ℃, pressure: micro negative pressure。

Difficulty of measurement：small flow rate, large amount of granular medium in flue gas. The differential pressure of differential pressure flowmeter is too small, the granular adhesive medium is blocked, and the pressure tap cannot be used.

UTF target flowmeter adopts a new sensor chip technology, which can well isolate the influence of dust in the measurement medium. After use, the measurement is stable and has been affirmed by the owner.
