Working principle of KOBOLD rotor flowmeter VKM-1108ROR200B:
When the measured fluid passes through the annular gap 3 formed by the conical tube and the float 2 from bottom to top, a differential pressure is generated at the upper and lower ends of the float, resulting in a rising force
When the lift force on the float is greater than the weight of the float immersed in the fluid, the float rises, and the annular area increases accordingly. The fluid flow velocity at the ring yard increases
As the pressure drops, the differential pressure between the upper and lower ends of the float decreases, and the upward force acting on the float also decreases until the upward force equals the float immersed in the fluid
When weighed, the float stabilizes at a certain height. The height of the float in the cone tube corresponds to the flow rate it passes through.
The KOBOLD rotor flowmeter VKM-1108ROR200B consists of a vertically tapered tube that expands from bottom to top and an axis along the tapered tube
Composed of a float group that moves up and down. Usually applicable to instruments with a diameter of 1540mm or more. Cone tube 5 and float 4 form a flow detection element.
There is an extension of the guide rod 3 inside the casing (not shown in Figure 3), which transmits the displacement of the float to the converter outside the casing through magnetic coupling and other methods
part The conversion part has two types: local indication and remote signal output. In addition to the right angle installation method, there are also inlet and outlet centerlines and cones
A straight through structure with concentric tubes, usually used for instruments with diameters less than 10-15mm.
