VSF(vortex shedding flowmeter)

VSF(vortex shedding flowmeter)

Working principle: According to the principle of fluid oscillation flow is measured, the fluid in the pipeline through the vortex flow transmitter in the triangular prism vortex occurred after the body up and down alternately produced is proportional to the velocity of the two columns of the vortex, the release of the vortex frequency and average velocity and vortex flow vortex occurred body fluid was related characteristics of body width, according to the relationship, The average velocity of the fluid flowing through the vortex-producing body can be calculated by the vortex frequency, which can be multiplied by the cross-sectional area to obtain the flow rate.
Working characteristics: (1) simple and firm structure, no moving parts, high reliability, long-term operation is very reliable; (2) Simple installation and convenient maintenance; The detection sensor does not directly contact the tested medium, stable performance, long life; The output is proportional to the flow of pulse signal, no zero drift, high precision; ⑤ Wide measuring range, range ratio can reach 1:10; ⑥ Less pressure loss, low operating cost, more energy-saving significance.
