Vortex Flowmeter With Temperature And Pressure Compensation

1. Introduction

LUGBML is based on Von Karman’s Vortex Principle, which adopts piezoelectric crystal as testing components. It is a new kind of stress detecting vortex flow meter. It has the advantage of wide range ratio, high accuracy, low pressure loss, good medium generality, pulse output proportional to flow, convenient to connect with computer and etc. As the detector probe of sensor and the vortex generating body are installed separately, and the high temperature resistant piezoelectric crystal doesn’t contact with medium, so the instrument is of simple structure, good generality and high stability.

LUGBML series Vortex Flow Meter sensor can be used to detect and measure the flow of all kinds of gas, liquid and steam.

LUGBML series Vortex Flow Meter can be used to match with our company’s ML6000 series Velocity Flowmeter. It can also match with a computer and sensors of temperature, pressure, or density to compose high accuracy mass flow or heat flow detecting and measuring system.



  • The structure of Vortex Flow Meter is simple and solid, no movable parts and it is very stable.

  • Simple installation and easy maintenance.

  • Wide measuring range, the ratio is up to 10:1.

  • The volume of fluid is compensated according to requirements, and the instrument coefficient does not need to be re-calibrated after the replacement of the accessories.

 Working Principle

Vortex flowmeter is based on Karman vortex street principle to measure the volume flow of gas, steam or liquid, volume flow or mass flow under standard conditions. It is mainly used for the flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.

It is characterized by small pressure loss, large measuring range and high precision. It is hardly affected by the parameters such as fluid density, pressure, temperature and viscosity when measuring the volume flow. There is no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. The vortex flowmeter adopts piezoelectric stress sensor with high reliability, which can work in the temperature range of - 20 ℃ to + 250 ℃. It has analog standard signal and digital pulse signal output. It is easy to use with computer and other digital systems. It is an advanced and ideal measuring instrument. 002
