Product Description Product DescriptionPipeline Vortex FlowmeteWorking principle:Vortex flow sensor measuring the flow of liquid of steam, gas and low viscosity according to Carmen and Strouhal relevant spiral produce and on the theory of the flow relationship. As shown in Figure - a triangular column is vertically inserted into the table body, which is the generating body of vortex. When there is medium flowing through the table body, Carmen vortex with opposite direction and regularity is alternately generated behind the triangular column. The separation frequency F of vortex is proportional to the flow velocity V of medium.Through the number of vortices detected by the sensor head, the fluid velocity can be calculated, and then the volume flow of the measured medium can be calculated according to the body diameter.Product ParametersMeasuring medium Gas, Liquid, SteamCaliber Flange-clamping typeDN15~DN300Flange typeDN15~DN300Inserted typeDN150~DN3000Measuring velocity range Gas 5 ~ 50M / S (can be expanded to 65m / s); liquid 0.5 ~ 5m / S (can be expanded to 7m / s)Measurement accuracy Flange clamping type and flange type: 1.0 and 1.5The accuracy of insertion measuring head is 1.0The accuracy of inserting industrial pipe is 2.5Temperature of mediumNormal temperature: - 25 oC ~ 100 oC,high temperature: - 25 oC ~ 150 oC or - 25 oC ~ 300 oCNominal pressure1.6Mpa; 2.5MPa; 4.0Mpa (available according to order)Output signalPulse voltage output signal High level 8 ~ 10V, low level 0.7 ~ 1.3V (explosion proof type: high level 4 ~ 5V, low level 0.7 ~ 1.3V)The pulse duty cycle is about 50%, and the transmission distance is 100 metersStandard voltage output signalDC4 ~ 20mA allows external load resistance less than 600 Ω (power supply is 24 V), and the transmission distance is 3000 mInstrument environmentTemperature: - 25 oC ~ + 55 oC Humidity: 5 ~ 90% RH (50 oC)MaterialThe body is made of SS304, the converter housing is made of aluminum alloy, and the body is made of SS316 Power SupplyDC12V ± 10%; DC24V ± 10%; Lithium battery 3.6V 7.5Ah x 2Explosion proof gradeIntrinsically safe exiallct1-t5, explosion-proof exdllbt4Protection levelIP65Clamp On Vortex FlowmeterWorking principle:Vortex flow sensor measuring the flow of liquid of steam, gas and low viscosity according to Carmen and Strouhal relevant spiral produce and on the theory of the flow relationship.
