V-cone flowmeter error situation

No matter how many sophisticated instruments will make mistakes, what are the errors in the V-cone flowmeter? The errors in V-cone flowmeter measurement are mainly caused by irregular installation and maintenance, etc. Today we Concerning the error of the V-cone flowmeter, the related introduction is made.

1, the first is the installation of non-standard V cone flowmeter site installation is not standardized, there may be several reasons: the lack of straight pipe before and after the process pipe, resulting in fluid instability, affect the measurement accuracy; installation direction has a problem, of course, this issue Basically, it will not happen unless it is caused by mistakes in the field installation. When measuring steam, the cooling device is not completely cooled, and the installation height is not the same. Secondly, it is the misoperation of the secondary instrument. When the V-cone flowmeter is used on the spot. , must be equipped with a differential pressure transmitter to normal use, so the performance of the differential pressure transmitter and the correct installation directly affects the overall accuracy of the V-cone flowmeter. The V-cone flowmeter still has successful operating experience in measuring mixed fluids, but it is necessary to pay attention to anti-corrosion of the differential pressure transmitter and open the drain valve regularly.

3, the last pressure tube clogging or leakage measurement of viscous easily crystallized medium, often due to heat and other reasons caused by the pressure tube, shut-off valve blockage, so that the differential pressure input to the differential pressure transmitter changes, resulting in measurements error. The elimination method is to conduct inspections on time, to conduct sewer cleaning or to manually push the pump to clear.

When measuring high-pressure or corrosive media, leakage of pressure guiding pipes or joints often occurs, causing pressure loss and differential pressure deviation. The elimination method is to conduct inspections on time and plug the loopholes.

Through the above description, our on-site maintenance technicians can easily find out the fault of the V-cone flowmeter and reduce the economic loss on site.
