Vortex type flow transmitter for sale supplier in China, with excellent vortex type flow transmitter R&D team. Buy bulk and wholesale flow meters from us.
SUP-LUGB vortex type flow transmitter is a kind of flowmeter that applies the principle of Karman vortex, used to measure the flow of liquid, gas and steam, also can Measure the turbid liquid containing tiny particles, impurities, widely used in petroleum, chemical, pharmaceutical, paper, metallurgy, electric power Environmental protection, food and other industries.
It is characterized by small pressure loss, large range, high accuracy, and is almost independent of fluid density, pressure, temperature, viscosity and other parameters when measuring the volume flow of working conditions. No movable mechanical parts, so high reliability and low maintenance. Instrument parameters can be long-term stability. Vortex flowmeter using piezoelectric stress sensor, high reliability, can work in the -20 ℃ ~ +250 ℃ operating temperature range.
There are analog standard signals, but also digital pulse signal output, easy to use with computers and other digital systems, is a more advanced, ideal measuring instruments.

A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. The generation of vortices is known as Karman's Vortices. The frequency of vortex shedding is a direct linear function of fluid velocity and frequency depends upon the shape and face width of bluff body.
Since the width of obstruction and inner diameter of the pipe will be more or less constant, the frequency is given by the expression:
f=StV/d
In the formula:
f – Karman vortex frequency generated at one side of bluff body (Hz)
St – strouhal number (non-dimensional number)
V – average speed of fluid (m/s)
d – width of bluff body (m)
