Annubar flowmeter (also known as flute-shaped constant velocity tube flowmeter and tobar tube flowmeter) is a differential pressure flowmeter. The pitot tube measurement principle is used to measure the differential pressure formed between the dynamic pressure upstream of the rod and the static pressure downstream, so as to achieve the purpose of measuring flow. The diameter of the measuring pipe is between DN50-DN4000. Annubar flowmeter is mainly used for the measurement of various energy sources such as liquid, fuel gas, steam and gas in industrial processes, with high stability and repeatability. The design theory of Annubar flowmeter conforms to the principle of Bernoulli equation and can be verified by JJG/640-1994.

Features
1. Convenient installation and disassembly, light weight, good complete set
2. High measurement accuracy, good stability, large range ratio
3. Cooperate with intelligent differential pressure transmitter to realize temperature and pressure compensation, 4~20mA signal output pressure loss is small, and energy saving effect is significant
4. The inevitable blockage problem when measuring dirty media, the online pull-out type can realize non-stop maintenance
5. It is suitable for the flow measurement of blast furnace gas, compressed air, steam and gas liquid and gas in industrial and mining enterprises with circular and rectangular pipelines
