Advantages and installation of plug-in vortex flowmeter
2011-12-23 10:39:19

的安装: Installation of plug-in vortex flowmeter :

At the position where the plug-in vortex flowmeter sensor is installed, a circular hole with a diameter of Φ107 is opened by gas cutting, and its axis is orthogonal to the axis of the pipeline by 90 ° C, so as to ensure accurate welding of the short flange pipe.

Flanged short pipes with corresponding diameters are welded at the round holes. After welding, ensure that the central axis of the flange short pipe is orthogonal to the central axis of the pipe.

Insert the test head into the pipe to a depth of 0.5 times the pipe diameter. 上的法兰盘与法兰短管的法兰盘之间,必须加装相应的密封垫,然后将法兰坚固好。 To measure the properties of the medium, a corresponding gasket must be installed between the flange on the plug-in vortex flowmeter and the flange of the flange short tube, and then the flange must be solid.

The handle rotates the lead screw and adjusts the detection head to match the flow direction

的最大优点是抗振性能特别好,无零点漂移,可靠性高。 The biggest advantage of the plug-in vortex flowmeter is that it has particularly good anti-vibration performance, no zero drift and high reliability. Through a lot of waveform analysis and spectrum analysis on the vortex flowmeter for a long time, the optimal probe shape, wall thickness, height, probe rod diameter and

The matched piezoelectric crystals are processed by advanced numerically controlled lathes to ensure the technical parameters such as coaxiality and finish of the processing, and special processing, so as to overcome the inherent self-oscillation frequency of the vortex flowmeter to the greatest extent. The effect on the signal
