Vortex Meters MSV

The MSV Vortex flow meter is a kind of speed type flow meter, which is based on karman vortex principle. The vortex frequency “f” is proportional to flow velocity “v”, so by measuring the karman vortex frequency can calculate the instantaneous flow rate.

Vortex flow meter is widely used in industry of petroleum, chemical, metallurgy, machinery, food, papermaking, and urban pipeline heating-apply, water-supply, gas-supply etc. to service the single-phase fluid of low viscosity liquid, gas, steam, etc. for process flow measuring and energy saving management.

Features:

• Low power consumption CPU processor, LCD display

• Installation & maintenance convenient, verification cycle about 2 years

• Simple structure, no moving parts, long-term reliably

• Range ability: 1:10, Turndown ratio 1:10

• Low pressure loss, low operation cost, energy saving

• Within certain range of Reynolds number, the output signal is not affected by the fluid’s changes in composition and physical properties. Instrument’s coefficient only relates to the vortex occurred body’s shape and size. Generally, it is not necessary to calibrate the instrument coefficient after replacing accessories.

• Both local display and long distance transmission to computer in control room available.

• Detecting component not directly contacting the measured medium, so instrument performance is stable.

• Built-in temperature & pressure compensation, current output photoelectric isolated, thus a good ability to suppress common mode disturbance.
