    High Accuracy Vortex Air Flow Meter For Big Diameter Pipeline 4 - 20mA Output

    High Accuracy Vortex Flow Meter for Big Diameter Pipeline with 4-20mA Output

    1. Introduction

    LUGBML is based on vonkarman's vortex principle and uses piezoelectric crystals as the test element. It is a new type of stress detection vortex flowmeter. It has the advantages of large turndown ratio, high accuracy, small pressure loss, good medium versatility, pulse output proportional to flow rate, and convenient connection with computer. Because the sensor's detection probe and eddy current generator are installed separately, the high temperature resistant piezoelectric crystal is not The contacting instrument has simple structure, good versatility and high stability. LUGBML series vortex flowmeter sensors can be used to detect and measure the flow of various gases, liquids and steam. It can be used with our company's ML6000 series vortex flowmeter. It can also cooperate with a computer and temperature, pressure, and density sensors to form a high-precision mass flow or heat flow detection system.


    2. Working Principle

    Vortex Flowmeter is a volume Flowmeter which is produced according to Carmen vortex principle to measure the volume flow rate of gas, steam or liquid, the volume flow rate of standard condition or the mass flow rate. Mainly used in industrial pipeline medium fluid flow measurement, such as gas, liquid, steam and other media.

    It is characterized by small pressure loss, large range and high precision, and is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. No moving mechanical parts, so high reliability, small maintenance. Instrument parameters can be stable for a long time. Vortex Flowmeter adopts piezoelectric stress sensor with high reliability and can work in the working temperature range of -20℃~250℃. There are analog standard signals, but also digital pulse signal output, easy to use with computer and other digital systems, is a more advanced, ideal measuring instrument.

    5. Design and installation


    It is very important to install the instrument, if not properly installed, it will affect the accuracy, service life and damage.


    1. In order to avoid switch sets with strong power, high frequency and high power, the meter power supply should be kept away from these devices.

    2. Avoid high temperature and radiation sources. If installation is required, take heat insulation ventilation measures.

    3. In order to avoid high temperature and enchanted gas, ventilation measures should be taken if installation is required.

    4. Vortex flowmeter should not be installed on the part of pipe shaking. If it must be installed on it, a clamping device and a vibration pad located in 2D should be added to enhance the shock resistance. It is better for the instrument to be installed indoors and outdoors, and pay attention to water proof. Pay special attention to the joints, make the cable lead u-shaped, so as to avoid water entering the amplifier body. Enough space should be saved at the installation place to facilitate the installation of the connection line and daily maintenance.
