Application Petroleum, chemical industry, metallurgy, machinery, food, paper, medicine, and urban pipeline heating, water supply, gas, steam and other single-phase fluid measurement and energy saving management Advantages Vortex flowmeter has wide range, high precision and easy installation and maintenance Working principle Vortex flowmeter applies the principle of fluid oscillation to measure the flow rate. When the fluid passes through vortex flow transmitter in the pipeline, two rows of vortexes proportional to the flow rate are generated alternately up and down after the vortex generator of the triangular column Instrument caliber(mm)liquidgas Measuring range (m3/h)Output frequency range(Hz)Measuring range (m3/h)Output frequency range(Hz) 251.2锝?625锝?368.8锝?5190锝?140 402锝?010锝?0027锝?05140锝?040 503锝?08锝?6035锝?8094锝?020 806.5锝?304.1锝?286锝?10055锝?90 10015锝?204.7锝?9133锝?70042锝?36 15030锝?502.8锝?3347锝?00033锝?80 20045锝?002锝?1560锝?00022锝?15 25065锝?2501.5锝?5890锝?100018锝?21 30095锝?0001.2锝?41360锝?800016锝?13 (300)100锝?5005.5锝?71560锝?560085锝?80 (400)180锝?0005.6锝?72750锝?700085锝?80 (500)300锝?5005.6锝?84300锝?300085锝?80 (600)450锝?5005.7锝?96100锝?100085锝?80 (800)750锝?00005.7锝?811000锝?1000085锝?80 (1000)1200锝?70005.8锝?817000锝?7000085锝?80 >(1000)protocol-protocol- Vortex flow sensor working condition flow range table (Note: The caliber (300)锝?1000) in the table is plug-in type)Flow Meter one years warranty website:http://www.alvifeng.com/flow-meter/
