Overview:     
       Model LWGY turbine flow meter adapts to measure the liquid rate and total flowrate of low viscosity. It can be widely used in the fields of Petrol, Chemical industry, Metallurgy, Scientific research for measuring or control. Several output and display methods can be selected.
Operating Principle:
       {0>,,,,,,,,,.<}0{>A permanent magnet, an induction coil and an amplifying unit are placed in the preamplifier. When the measured fluid is flowing across the flow meter, it drives the turbine to rotate, and the turbine periodically changes reluctance value of the magnetic circuit, which makes the magnetic flux passing the coil vary periodically, thus to induce in the coil the pulsating current signal, which is delivered to a secondary instrument after amplification and treatment, or provide in-situ display, so as to achieve flow rate accumulation.<0}                    
{0>,,.<}0{>        Within the measuring range, the impeller rotate is positively proportional to the flow rate, namely the impulse total is in direct ratio to the quantity flow.<0}{0>"K"(/L).<}0{>Ratio of the two is termed as K-factoryt, which is indicated by letter "K" (P/L).<0}{0>.<}0{>The instrument constant value of each flow meter is educed by means of actual flow calibration.<0}{0>fN,K,q(L/s)Q(L).<}0{>Divide impulse frequency f and impulse total N measured by the flow meter by instrument constant K of it respectively, the flow rate rate q (L/s) and the quantity Q (L) will be calculated.<0}{0>:<}0{>i.e. <0}
        q = ƒ/K  (L /s ). 
        Q = N/K (L)   
 Medium:
      Normal TEMP.:Water, Weak corrosive organic solvent, liquid medicine, gasoline, diesel and other clean media
        Low      TEMP.:liquid nitrogen,liquid oxygen and so on
        Hight    TEMP: hot  water,hot oil  and  so on

      {0>,(),.<}0{>In order to ensure a high measuring accuracy, the flow meter shall be horizontally installed on a horizontal pipeline, and the arrow sign on the flow meter that indicates the flow direction shall be made consistent with the liquid flow direction.<0}{0>,,.<}0{>In case a vertical installation is a must, the liquid shall be made flow from the down to top, so that the body of the flow meter will be ensured full of liquid.
     To eliminate influences of the measuring accuracy resulting from uneven flow velocity distribution of cross section inside a pipeline, both the upperstream and the downstream of the flow meter shall be installed with definite straight lengths, or be installed with flow straighteners to substitute some straight lengths.<0}
