This vortex is called Karman vortex, enabling you to know the flowrate from the frequency created. A vortex flowmeter is applicable to liquid, gas, and steam. It has no moving parts and features low pressure loss. It is an easy-to-use flowmeter with high durability and repeatability and is widely adopted in various fields including calorie transactions and calorie control.

Effect of Environment Temperature:
Has no effect on digital and pulse output
For analog output, ± 0.15% of range(-25 ~ 85°C)
Effect of Installation Location:
When the instrument is installed in horizontal, vertical, or sloped pipe, it can meet accuracy index.
Magnetic Interference:
HART Analog: in the case of 30A/m, the output error is less than ± 0.15% of full scale, in line with the IEC60770-1984
Effect of Power Supply:
HART Analog: less than 0.005% of full scale/ per volt
