Measurement and control of seismic vortex flowmeter measurement accuracy and stability

Project Overview

"Anti-vibration vortex flowmeter" is the latest generation product independently developed by Supmea Measurement and Control, which solves the international problems of traditional vortex flow metering range of small range and poor anti-vibration performance. The LUB series vortex flowmeter has a wider measuring range, better anti-vibration effect, and more stable operation. It is the first choice instrument for enterprise internal measurement assessment and trade settlement.

1. Working principle

The working principle of the anti-seismic vortex flowmeter is based on the Karman vortex principle. When the fluid passes through the triangular prism-shaped vortex generator in the flow meter, two alternating rows of vortices will be generated behind it. The frequency of these vortices is directly proportional to the flow rate of the fluid. By measuring the frequency of these vortices, the flow rate of the fluid can be accurately calculated. The sensor generates a changing charge signal synchronously with the pressure pulsation of the vortex. After the signal is amplified, filtered, shaped and processed by an electronic amplifier, a pulse signal proportional to the flow signal is output, thereby realizing flow measurement.

2. What is the measurement accuracy and stability of Hesheng Measurement and Control’s anti-seismic vortex flowmeter?

(1) Ultra-high-precision measurement: The main components of the instrument are processed using the most advanced CNC machine tools and fully automated welding equipment in the country. Together with advanced digital processing circuits and software programs, the measurement accuracy of the instrument is even higher. 0.75%, which fully meets the enterprise's internal measurement assessment and trade settlement measurement.

(2) Stability: Hesheng Measurement and Control's anti-seismic vortex flowmeter can still maintain high stability and accuracy in harsh environments with high intensity of pipeline vibration. It can accurately measure even at ultra-low flow rates, showing its excellent anti-vibration performance and stability. LUB series products also feature adaptive digital signal processing, simple parameter setting, and clear and intuitive display, which all help to improve the stability and reliability of measurements.

3. Other advantages of LUB anti-seismic vortex flowmeter:

(1) Ultra-wide range measurement: Precisely control the flow output signal of the sensor probe, and DSP ensures accurate capture of low The vortex signal in the flow area significantly improves the stability of measurement and broadens the range ratio of the flow meter, with the range ratio up to 1:35.

(2) Spectrum analysis capability: Hesheng Measurement and Control LUB series anti-seismic vortex flowmeter has DSP spectrum signal analysis capability, which can analyze the fluid signal generated in the digital vortex flowmeter and analyze the dynamic data based on the dynamic data. Compare the situation with the self-prepared database and automatically select the best state under the usage conditions.

IV. Application fields

Anti-seismic vortex flowmeters are widely used in flow measurement and control in petroleum, chemical, pharmaceutical, food and other industries. Due to its seismic performance, it is especially suitable for nuclear power plants, subways and other working conditions that require earthquake resistance. In addition, the shock-resistant vortex flowmeter can maintain stable measurement performance in some harsh environments, such as high temperature, high pressure, high viscosity, etc.
