Stainless Steel Turbine Flowmeter for Fuel or Chemical Flow Monitoring Process Control¹

Product Description Product DescriptionOverview:   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>,,.<}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><}0{><0}<><}0{>"K"(/L).<}0{><0}{0><}0{><0}<><}0{>Ratio of the two is termed as K-factoryt, which is indicated by letter "K" (P/L).<0}{0><}0{><0}{0><}0{><0}<><}0{>.<}0{><0}{0><}0{><0}{0><}0{><0}<><}0{>The instrument constant value of each flow meter is educed by means of actual flow calibration.<0}{0><}0{><0}{0><}0{><0}{0><}0{><0}<><}0{>fN,K,q(L/s)Q(L).<}0{><0}{0><}0{><0}{0><}0{><0}{0><}0{><0}<><}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{><0}{0><}0{><0}{0><}0{><0}{0><}0{><0}<><}0{>:<}0{><0}{0><}0{><0}{0><}0{><0}{0><}0{><0}{0><}0{><0}<><}0{>i.e. <0}<><}0{><0}{0><}0{><0}{0><}0{><0}{0><}0{><0}{0><}0{><0}<><}0{>q = ?/K(L /s ).
