PRODUCT INTRODUCTION


The LUGB series vortex flow meter uses the Karman vortex principle for flow measurement. It is mainly used for flow measurement of industrial pipeline fluids, such as gases, liquids, steam and other media. It is characterized by small pressure loss, large measuring range, and high accuracy. It is hardly affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. There are no movable mechanical parts, so the reliability is high and the maintenance is small.


MEASURING PRINCIPLE





As shown in the figure above:

When the fluid flows through the vortex flowmeter sensor in the pipeline, two rows of vortices proportional to the flow velocity are alternately generated behind the vortex generator of the triangular column. The release frequency of the vortex is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator. Relevant, can be expressed by the following formula:

 

F=St*v/d

Where:

F: Release frequency of Carmen Vortex Street

St: Strouhal number (vortex flowmeter coefficient)

V: Flow rate



FEATURES


It can measure the flow of gas, liquid, saturated steam and superheated steam at the same time;

High measurement accuracy: better than 1.0%FS;

Simple and firm structure, no moving parts, high reliability, and very reliable long-term operation;

Brand new dot matrix Chinese character LCD intelligent display, which is more convenient to use and operate;

Simple installation, convenient operation and maintenance;

The detection sensor does not directly contact the measured medium, with stable performance and long service life;

The output is a pulse signal proportional to the flow rate, no zero drift, high precision;

Wide measuring range, range ratio up to 1:10;

Small pressure loss, low operating cost, more energy-saving significance;

Battery-powered type can work continuously for more than two years without external power supply.

TYPE CHARACTERISTICS


                                                                                                                                                                                       On-site display type                  Remote type



Display remote transmission can be divided into on-site display type and remote transmission display type:

On-site display type: often used for on-site observation, the display is intuitive, without the need to lay cables.

Remote display type: mostly used for long-distance observation, or installed in a position that is not conducive to observation.

On-site display + remote transmission: This form combines the advantages of the above two forms into one, which can be displayed on-site and remotely transmitted display control.

 


                                                                                                                                                                                     Lithium battery powered vortex flow meter


With high-capacity lithium battery:

No need for external power supply on site, large LED screen LCD display.

It can work continuously for more than two years, and the lithium battery can be replaced.


Integrated temperature and pressure compensation


1. Lithium battery is powered on site, no external power supply is needed.

2. With temperature and pressure compensation sensor, no separate compensation is required.

3. The automatic compensation module can intelligently convert the volume flow into mass flow according to the compensation parameters.

4. Large-screen LCD intelligent display, which can display temperature, pressure, volume flow, mass flow, etc.
