Product Description
Vortex flowmeters are mainly used for flow measurement of industrial pipeline fluids, such as gas, liquid, vapor and other media. It is characterized by small pressure loss, large measuring range, and high accuracy. It is hardly affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. [1] Using piezoelectric stress sensor, high reliability, can work in the working temperature range of -20℃～+250℃. It has analog standard signal and digital pulse signal output. It is easy to use with computer and other digital systems. It is a relatively advanced and ideal flow meter.

Main function
1. The temperature and pressure compensation function is integrated in the meter body at the same time, which can measure the standard volume flow or standard mass flow of the fluid.
2. Fully intelligent and digital circuit design, which can automatically compensate the density of the measured fluid or volume calculation under standard conditions.
3. The new digital filtering and correction functions make the flow measurement more accurate and reliable.
4. The battery-powered type can work continuously for more than two years without external power supply.
5. Brand new dot matrix LCD display of Chinese characters, which is more convenient to use and operate.
Principle
If a triangular cylindrical vortex generator is installed in the fluid, regular vortices are alternately generated from both sides of the vortex generator. This type of vortex is called the Karman vortex. As shown in the figure on the right, the vortex array is arranged asymmetrically downstream of the vortex generator...
The vortex flowmeter is composed of a vortex generator designed in the flow field, a detection probe, and corresponding electronic circuits. When the fluid flows through the vortex generator, two alternating rows of vortices are formed on both sides of it. This vortex is called the Karman vortex street. On the basis of the Karman vortex street theory, Strohar proposed that the frequency of the Karman vortex street is proportional to the flow velocity of the fluid, and gave the relationship between the frequency and the flow velocity:
f = St × V/d
Where: f vortex street frequency (Hz)
The average flow velocity on both sides of the V vortex generator (m/s)
St Strohal coefficient (constant)
These alternating vortices form a series of alternating negative pressures. The pressure acts on the detection probe to generate a series of alternating electrical signals. After conversion, shaping, and amplification by the preamplifier, the output is synchronized with the vortex. Proportional pulse frequency signal or standard signal.
