What is the working principle of the waist wheel flowmeter? The waist wheel flowmeter, also known as the Roots flowmeter, works based on one or two pairs of waist wheels that can rotate tangentially. Its internal structure includes a measuring chamber, which is composed of the outer edge of the waist wheel and the inner wall of the shell, forming a "bucket" space with a fixed volume. When the fluid passes through under the pressure difference, the waist wheel will rotate in the positive direction. The working process of the waist wheel can be divided into four stages: firstly, the waist wheel Q1 acts as the driving wheel, pushing Q2 to rotate and discharge the fluid from the measuring chamber; Continuing with the grip width, Q2 becomes the driving wheel and the above process is repeated. Each waist wheel rotates 180 degrees to complete one measurement. By measuring the number of rotations of the waist wheel and the volume of the measuring chamber, the fluid volume can be calculated. The waist wheel flowmeter is suitable for measuring clean liquids, especially oil products, with high accuracy, up to 0.1-0.5 levels. Although its main disadvantages are large size, high pressure loss, and vibration, Pibi can significantly reduce vibration and noise during operation by using two pairs of waist wheel structures at a 45 degree angle. This flowmeter is widely used in the fields of petrochemicals, electricity, metallurgy, transportation, national defense, and commerce due to its innovative design, high precision, and easy installation, such as measuring gasoline, kerosene, and light diesel. 2.

What is the working principle of the waist wheel flowmeter? The waist wheel flowmeter, also known as the Roots flowmeter, belongs to the volumetric flowmeter and is a high-precision measuring instrument used for continuous or intermittent measurement of flow in pipelines. It is commonly used for flow measurement of large-diameter gas, liquid, and steam medium fluids in industrial pipelines.
. The working principle of the waist wheel flowmeter is that there is a measuring chamber inside the housing of the waist wheel flowmeter, and there are one or two pairs of waist wheels that can rotate tangentially in the measuring chamber. A pair of transmission gears are coaxially installed with two search wheels outside the casing of the flowmeter, and they mesh with each other to enable the two waist wheels to interlock. When fluid passes through the flowmeter, the two waist wheels will rotate in the positive direction under the action of the fluid differential pressure at the inlet and outlet of the flowmeter. The liquid in the measuring chamber keeps flowing in and out, and the flui
