Electromagnetic flowmeter is only suitable for installation
Electromagnetic flowmeter When fluid moving along the axial direction enters the flow sensor inlet, the vortex episomal blade forces the fluid to rotate stationary, thus vortexing in the center of the vortex episode. The vortex flow precesses in the venturi tube, and the throttle section is suddenly throttled to decelerate the vortex flow. When the vortex flow enters the dispersion section, the helical precession is forced due to the recirculation. At this time, the rotational frequency of the vortex flow is inversely proportional to the flow velocity of the fluid. The piezoelectric sensor detects that a strong electrical signal is resolved by a pre-scaler or the like to obtain the flow signal that we need. 1. The former is the combination of the sensor and the transmitter, and the latter is the sensor and the transmitter respectively. 2. In order to obtain a high pressure difference at a small flow rate, the former is practically smaller than 50 mm (typical values are 10 mm and 20 mm), while the standard throttling installation is only practical for 50 mm and 50 mm or more, otherwise it will occur during processing. difficult. 3. The former adopts the method of actual flow calibration to ensure the accuracy of the measurement, and then the calibration is not required if the standard throttle installation is used. 4. The former is only suitable for installation on the degree pipeline, but there is no such restriction afterwards.
