working principle

Bottom-up when the measured medium through the measuring tube, the float rises and lower ends are formed to produce a differential pressure force, suffered when the float rises immersed in a fluid force is greater than the weight of the float, the float will rise, annulus area increases, the annulus fluid flow rate at a rapid decline in the float upper and lower ends to reduce the differential pressure acting on the lifting force of the float decreases, until the lifting force of the float and the weight balance immersed in the fluid, the float will be stable in the first position, i.e., the level of the float position It corresponds to the size of the measured medium flow. Built-in magnet floats in the float moves up and down with the media, the magnetic field varies with the movement of the float. By a magnetic sensor magnetic field changes will be converted into electrical signals by the analog to digital conversion, digital filtering, temperature compensation, the microprocessor processing, digital to analog conversion, LCD, switch control output to display the instantaneous flow rate and cumulative flow size and be control.
