Intelligent Vortex Flowmeter
Description
The intelligent vortex flowmeter is a fluid oscillation instrument designed based on the Karman vortex street principle, used to measure the volumetric flow of gas, liquid, steam and other media in industrial pipelines.
Equipped with a piezoelectric stress sensor, it features no moving parts, low pressure loss, wide turndown ratio (above 10:1) and high measurement accuracy. Its measurement is barely affected by fluid physical parameters.
The instrument operates within -40℃ ~ +350℃, and supports 3-wire voltage pulse output or standard 4~20mA current signal output.
