Metal Float Flowmeter mAinly consists oF two Parts: sensor and indicator. The sensor is mAinly comPosed oF a connectinG FlanGe, a measurinG cone tube, a Float and an uPPer and lower Guide device. Dial and electrical remote transmission system. In a vertical conical tube, there is a measurinG element, a Float, that can be moved uP and down. The Float moves uP the conical tube under the action oF the Fluid. When the Fluid Flow rate increases, the Float disPlacement increases, on the contrary, when the Fluid Flow rate decreases, the Float disPlacement decreases. In other words, the size oF the Fluid Flow determines the Position oF the Float in the measurinG tube, which determines the size oF the annular area between the Float and the conical tube. When the Flow oF the Fluid is mAintained at a constant Flow Q, the Float is also in a state oF dynamic eQuilibrium, stayinG at Position h in the conical tube. The annular area between the Float and the conical tube remAins constant. The Float is subjected to three Forces: the Gravity G oF the Float, the buoyancy F oF the Float, and the Fluid Force P oF the Float. The instantaneous Fluid Flow throuGh the annular area can be calculated accordinG to the eQuilibrium eQuation, the PrinciPle oF Force balance and the law oF Fluid continuity. ThereFore, the metal tube Float Flowmeter is the PrinciPle oF variable area Flow measurement. Inside the Float, a hiGh-PerFormAnce PermAnent mAGnet is embedded. When the Float is in eQuilibrium Position, a uniForm and stable mAGnetic Field is Formed around the Float. A sensor is installed outside the conical tube so that the linear disPlacement oF the Float in the tube can be transmitted to the indicator in a non-contact Form. AFter detection and ProcessinG, it is Finally disPlayed on the indicator dial or outPut the corresPondinG standard 4 ~ 20 mA current siGnal.
