Variable Area Flowmeter

KNOWLEDGE BASE --- Working Principle of Variable Area Flowmeter

The measured medium flows through the float of the measuring tube from bottom to top and the upper and lower ends generate differential pressure to form a lift force. When the lift force received by the float is greater than the weight of the float immersed in the fluid, the float will rise, and the area of the annular gap will increase accordingly. The fluid flow rate drops rapidly, the differential pressure at the upper and lower ends of the float decreases, and the lifting force acting on the float decreases with it. When the lifting force is balanced with the weight of the float immersed in the fluid, the float is stable at a certain position, corresponding to the size of the measured medium flow. The float has a built-in magnetic steel. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.

As for the common type of variable area flowmeter, the follow-up magnet in the local indicator is coupled with the magnet in the float to rotate, and at the same time drive the pointer to indicate the flow rate at this time through the dial.

On the other hand, for the intelligent type, the follow-up magnet in the intelligent indicator is coupled with the magnet in the float, and rotates, and drives the sensor magnet and pointer at the same time, and converts the magnetic field change into an electrical signal through a magnetic sensor. After conversion, digital filtering, temperature compensation, microprocessor processing, D/A output, LCD liquid crystal display will show the instantaneous flow and cumulative flow.
