Micro flow metal rotor flowmeter structure and measurement principle:
1, structure:
It consists of three major components:
a. Indicators (intelligent indicators, local indicators);
b. floats;
c, taper measurement room.
2, the principle of measurement:
Measured medium from the bottom up through the cone measuring tube when the upper and lower ends of the float pressure rise to form a force, when the float is subjected to greater lifting force immersed in the fluid float weight, the float will rise, the ring area will increase Large, the fluid velocity at the annulus immediately drops, the differential pressure at the upper and lower ends of the float decreases, and the lifting force acting on the float also decreases. Until the rising force is equal to the weight of the float immersed in the fluid, the float is stabilized at a certain height. The position of the float corresponds to the size of the measured medium flow. The float is equipped with magnetic steel. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.
a. For the on-site type, the rotating magnetic steel in the local indicator is coupled with the magnetic steel in the float, and the rotation occurs. At the same time, the pointer is driven, and the flow volume at this time is indicated through the dial.
b. For smart type, a solid state magnetic sensor in the intelligent indicator converts the change of the magnetic field into an electrical signal, and displays the flow rate through A/D conversion, microprocessor, D/A output, and LCD liquid crystal display. Size and cumulative flow.
