1. The difference between Biotaba flowmeter and Delta flowmeter
“ The Bitoba flowmeter is a patented product of Tsinghua University and the only flowmeter product recommended by the National Development and Reform Commission. It is the most advanced instrument for measuring fluid flow in China certified by the Chinese Academy of Metrology, and is also the most advanced flowmeter in the world (currently only China, Germany, and the United States have this technology). This statement is so scary, flashy, and extremely repulsive to us technicians! The most obvious difference between Bitoba and Deltaba is that the former has fewer measurement points, while the latter has multi-point measurement and can easily achieve grid Fabry Perot measurement in the pipeline. The former cannot achieve this, and the correction explanation for this fatal flaw is Xi Xiang: "After a lot of blowing, it has created a plump and plump body. The database is implemented through correction calculations. Those who are slightly knowledgeable should know that the straight sections of air ducts in industrial sites are often relatively small, which cannot meet the measurement requirements. Moreover, the wind field is quite complicated, with baffle doors, supports, and slow air distribution all making the wind field very difficult. Especially for large diameter air ducts, the flow velocity difference at each point is extremely large, and many places are even reversed. Under such conditions, can it be solved through database correction? Based on my understanding, there is nothing particularly special about Bituoba, it can be said that it has only made several optimizations on the basis of the classic Bituoba.

3. What are the differences between orifice plates, pitot tubes, and Venturi flow meters?? Orifice flowmeter, pitot tube, Venturi flowmeter, and rotor flowmeter are all different flow measurement tools, and their differences mainly lie in their working principles and applicable ranges. 1. Orifice flowmeter: measures flow rate using the local pressure difference generated by the orifice plate holes. It is suitable for measuring medium to high viscosity liquids and gases, but it should be noted that the measurement accuracy will be greatly affected under low flow rate and high viscosity fluid conditions.
2. Pitot tube: It uses the relative motion between the fluid in motion and a stationary object to measure the flow rate, curvature, and flow rate. The difference is that it requires a signal to be placed in the fluid to measure the flow rate, receive the signal externally, and calculate the flow rate.
3. Venturi flowmeter: measures the flow rate by using the pressure difference generated in the contraction section of the fluid moving at high speed in the pipeline.
. It is suitable for measuring low to medium viscosity liquids and gases, with advantages such as low pressure loss in pipelines, higher accuracy than orifice plates under low Reynolds number media and large pipe diameter conditions, but higher manufacturing costs.4. Rotary flowmeter: uses the volume of liquid flowing through the rotor to achieve flow measurement. It is suitable for measuring liquids and gases with high viscosity, and has advantages such as high measurement accuracy.
