China Supplier Vortex Flow Meter for Compressed Air / Steam

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.

2. Application

LUGBML series is suitable for oil,chemical industry,metallurgy,heating power,spinning,pape rmaking ,etc. Be use of control: over-heating vapor, saturation vapor, compressed air,ordinary air(oxygen, nitrogen, hydrogen, natural gas, coal gas ,etc),water and liquid (water, petrol ,alcohol, benzene ,etc.)

3.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.
