Temperature Pressure Compensation Vortex Flowmeter High Quality

1. Introduction

LUGBML is based on vonkarman's vortex principle and uses pyelectron crystals as a test element. It is a new type of stress detection vortex street flow meter. It has the advantages of large range ratio, high precision, small pressure loss, good media versatility, pulse output and flow ratio, easy to connect with the computer, because the sensor probe and vortex generator are installed separately, high temperature-resistant die-electric crystals do not touch the instrument simple structure, good versatility, high stability. The LUGBML series of vortex street flow meter sensors can be used to detect and measure the flow of a wide range of gases, liquids and vapors. Can be used with my company ML6000 series vortex street flow meters. It can also be combined with computers and temperature, pressure, 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.

It is mainly used for flow measurement of medium fluid in industrial pipeline, such as gas, liquid, steam and other media.

It is characterized by small pressure loss, large measuring range and high precision. It is almost unaffected by parameters such as fluid density, pressure, temperature and viscosity when measuring volume flow under working conditions. There are no moving mechanical parts, so the reliability is high and the maintenance is small. Instrument parameters can be stable for a long time. Vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of-20℃ ~+250℃. There are analog standard signals and digital pulse signals, which are easy to be used with digital systems such as computers. It is an advanced and ideal measuring instrument.
