Vortex Flowmeter Instruction

Vortex Flowmeter is on the principle of Karman street, to measure liquid, gas and vapour even turbid liquid including micro grain and impurity.
Applications: petroleum, chemical industry, paper making, metallurgy, electric force, environmental protection, food industry and etc.

Working Principle

LUGB & LUCB Vortex flowmeter work on the principle of generatedvortex and relation between vortex and flow by theory of Karman and Strouhal, which specialize in measurement of steam, gas and liquid of lower viscosity.
As shown in below illustration, medium flows through bluff body and then vortex is generated, vortices are alternately formed on both sides with opposite directions of rotation, Vortices frequency is directly proportional to medium velocity. Through numbers of vortices that is measured by sensor head,medium velocity is calculated, plus flowmeter diameter, final volumeflow come out.

Computational formula as follows:
F=St*V/md ………………………………………………..Formula 1
Q=3600*F/K ………………………………………….Formula 2
M=Q*p ………………………………………………………..Formula 3
Among Formula:

• F Fluid flow through bluff body generate frequency of vortex ( Unit : Hz)
• St… Strouhal constant ( zero dimension )
• V Mean velocity of fluid inside the pipeline ( Unit : m/s)
• m The ratio between Lune Circulation area of bluff body at both sides and cross-sectional area ( Unit: zero dimension )
• d Upstream face width of bluff body inside vortex flowmeter ( Unit : m )
• D Inside diameter (ID) of vortex flowmeter ( Unit : m )
• Q Instantaneous volume flow ( Unit : m3 / h )
• K Instrument coefficient of vortex flowmeter ( Unit : pulses / m3 )
• M Instantaneous mass flow ( Unit : kg/ h ) Fluid density ( Unit : kg/ m3 )

Note: vortex flowmeter “K” coefficient is corresponding with one diameter, the exact “K” value should be calibrated in practice. Viz. one cubic meter fluid through sensor output numbers of pulse under working condition.

Installation Instruction

Installation Place and Environment Selection Try to avoid strong power equipment, high-frequency equipment and strong power switchgear.
Try to avoid high-temp thermal source and source of radiant heating; outdoor installation should do some measures of sun-shading and rain shelter.
Try to avoid shock places and corrosion environment ; meanwhile, easy maintenance should be considered. Reasonable and correct installation position. Installation position should avoid strong shock pipeline, or take some measures of shock absorption. Horizontal, vertical and slanting installation. Liquid measuring ensure flow direction from low to high. Gas measuring, direction no required.
When measuring vapor or high-temp gas, flow meter body pillar should be at an angle of 45 Deg with vertical direction.
Grounding requirement. When pipelines without available grounding conditions, a ground-wire is essential between housing and earth. Straight length requirement In order to correct measurement, upstream or downstream of flow meter should obligate enough straight length. No components to effect fluid velocity in upstream of flow meter. All types of straight length installation reference:
LUGB Vortex Flowmeter Straight Length Size Drafts    

Installation and welding of flow meter
LUGB Vortex diameter is accordant to upstream and downstream tubing diameter at installation point; sensor is concentric with pipeline; prohibit gaskets between sensor and flanges bulge out into pipeline. Make sure that the connection end face of insertion-version vortex flowmeter parallel to the pipe axis. Details as per fig.4.
After initial installation, when medium is steam or other high-temp medium, flanges & bolts should be re-tightened when medium full of pipeline. Do heat reservation measures for pipeline in order to protect amplifier.
LUGB Vortex installation & Welding Reference FigureBe attention: concerning P/T compensation integrated vortex flow meter, to avoid high-temp or liner shock damage pressure transmitter, Pressure control valve must be closed before medium is full of pipeline. When medium full of pipeline meanwhile approaching working temperature and pressure, slowly turn on control valve. Pressure tapping and pressure detector should be done heat reservation if flow meter outdoor installation.
