Pipeline vibration and vortex flowmeter measurement

Intelligent vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. The characteristics of vortex flowmeter are small pressure loss, large measuring range, high accuracy, and it is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring the flow rate under working conditions. There are no moving mechanical parts, so the reliability is high, the maintenance is small, and the instrument parameters can be stable for a long time. The vortex flowmeter uses an electric stress sensor with high reliability, and can operate in an operating temperature range of -25℃~+350℃. Vortex flowmeter

It has both analog standard signal and digital pulse signal output, and is easy to use with digital systems such as computers. It is a relatively advanced and ideal flow meter.

Does the measurement have any impact? As follows:

1. The error of the vortex flowmeter instrument coefficient increases with the increase of pipeline vibration acceleration, and the overall seismic performance is poor. Taking the pipeline vibration frequency of 100Hz as an example, the vertical seismic acceleration is 0.05g

, horizontal seismic acceleration is 0.2g

.

2. Under the same pipeline vibration acceleration conditions, no matter how the vibration frequency changes, the instrument coefficient error of the vortex flowmeter tends to decrease with the increase of flow rate, and is most affected by pipeline vibration at small flow rates.

3. Under the same pipeline vibration acceleration conditions, the instrument coefficient error of the vortex flowmeter decreases with the increase of pipeline vibration frequency.

4. Compared with the vertical direction, the instrument coefficient error of the vortex flowmeter is smaller in the horizontal pipeline vibration direction and the seismic resistance is better.

Therefore, it provides convenience for users
