1. The difference between Pitot tube flowmeter and Velbar flowmeter. Pitot tube principle was invented by French physicist H. Pitot. Pitot tube, also known as pitot tube, is a pressure unit. Pitot tube is the transliteration of the English pitot tube principle pressure element, so our registered trademark Pitot tube is certified by the Chinese Academy of Metrology. It is the most advanced instrument for measuring fluid flow in China and also the most advanced in the world (currently only China, Germany, and the United States have this technology) Energy saving products promoted by the National Development and Reform Commission

1. Measurement Principle ★ The Biota sensor consists of a set of pressure tapping holes, which use the pitot tube principle to extract fluid flow velocity (total pressure static pressure=dynamic pressure) and convert it into a differential pressure flowmeter with fluid volume flow rate and mass flow rate. The pitot tube principle has been widely used in the aerospace industry for a long time. For example, testing and inspection of aircraft wind tunnels, aerodynamic testing of aircraft engines, speed measuring rods for aircraft flight speed, etc. The Bitoba flowmeter inserts a probe into the pipeline, and the total pressure hole is aligned with the incoming flow direction of the positive fluid, while the static pressure hole is aligned with the outgoing flow direction of the positive fluid. The difference between the total pressure and static pressure, which is the desired differential pressure, is obtained through a high-precision transmitter, and the fluid flow rate is calculated based on the differential pressure. The Weiliba flowmeter consists of multiple pressure tapping holes, which

measure the differential pressure at unknown points in the pipeline. Finally, the average differential pressure is calculated through a transmitter and converted into flow rate to calculate the flow rate. Explanation of Differences and Similarities: In fluid mechanics, the relationship between flow velocity (converted from differential pressure to flow velocity) and flow rate is not a simple linear correspondence, so only segmented measurement can be more accurate, and the more segments there are, the higher the accuracy. The Bitoba flowmeter consists of a set of pressure tapping holes, and is designed in various models such as ordinary type, main steam type, and anti blocking type according to the characteristics of different media. The measuring component does not contain any electronic components, and its accuracy is not affected by external factors, ensuring stable pressure sensing function for a long time. The uniform velocity tube flowmeter consists of multiple pressure tapping holes, which obtain the flow rate at an unknown point inside the pipeline, and finally calculate it using a transmitter.

2. Fluid Conditions ★ Bitoba Sensor - Suitable for measuring any pipeline fluid - can measure both single-phase and bidirectional fluid flow (such as water gas mixed flow). - Low requirements for straight pipelines - Excellent measurement effect for media containing impurities and prone to blockage ★ Powerful excavator flowmeter - The medium must be filled in the pipeline - The fluid must be single-phase flow, and bidirectional flow (such as water gas mixed flow) cannot be measured.

III. Characteristics of Sensors ★ Compared with other forms of differential pressure flow meters, the Bitoba flow sensor has th
