Vortex flowmeter advantages and disadvantages
2023-12-08
Main advantages of vortex flowmeter:
1, simple structure, firm, easy installation and maintenance, compared with the throttling device to reduce leakage, blockage and freezing phenomenon.
2, the accuracy is high, the relative deviation is between 11 minus 1% and 1.5%.
3, the measurement range is wide, under a reasonable caliber, the range can reach 20:1.
4, pressure reduction, about 25% to 50% of the throttle type differential pressure flowmeter
5, within a certain range of Reynolds number, the output frequency is not affected by the physical properties (density and viscosity) and composition of the fluid, and the instrument coefficient is only related to the shape and size of the vortex generator and the pipeline.
6, vortex flowmeter adopts piezoelectric stress sensor, high reliability, can work in the operating temperature range of -20C~+250%C.
7, the vortex flowmeter has analog standard signals, but also digital pulse signal output, easy to use with computers and other digital systems.
Main disadvantages of vortex flowmeter:
1, the pipeline mechanical vibration is more sensitive, not suitable for strong vibration occasions.
2, the larger the diameter, the lower the resolution, the general full tube flowmeter for DN400 below.
3, when the fluid temperature is too high, the sensor production will be difficult. The general logistics temperature is less than or equal to 420°C.
4, when the fluid has pressure pulsation or flow pulsation, the indicating value is greatly high, the impact is greater, that is, it is not suitable for pulsating flow.
