Comparison of vibration-resistant vortex flowmeter and standardized vortex flowmeter

Project Overview

Vortex flowmeter is a commonly used flow meter in the world. Because of its characteristics of small pressure loss, reliable long-term operation, high accuracy, simple installation, and convenient maintenance, it is widely used in thermoelectricity, petroleum, chemical industry, metallurgy and other industries. Department, it is also used in municipal engineering and environmental protection industries to implement control of liquids (such as water, oil, petroleum, alcohol and other liquids), gases (such as air, oxygen, nitrogen, natural gas, coal gas, etc.) and steam (saturated steam, Superheated steam) flow measurement detection and control. However, in actual application, due to different measurement environments, in terms of anti-vibration selection, the vortex flowmeters used are divided into standardized vortex flowmeters and anti-vibration vortex flowmeters. The standardized vortex flowmeter has no movable mechanical parts, so this instrument has a long life, less maintenance, stable instrument coefficient, and will not be affected by changes in the pressure, temperature, viscosity and other parameters of the medium in various working environments. However, it will be affected by its working principle. Traditional vortex flowmeters are not easy to install under vibration conditions. The anti-vibration vortex flowmeter is based on the standardized vortex flowmeter and solves the problems of small range and poor anti-vibration performance. The LUB series vortex flowmeter is equipped with DSP signal processing circuit and anti-vibration algorithm, and is equipped with a mature piezoelectric crystal sensor. After long-term field testing and operation, its performance is reliable. Even under complex working conditions, the digital vortex flowmeter can effectively identify the signals generated by the body and the signals generated by vibration and perform shielding processing to achieve accurate and stable operation.
