Smart Vortex Flowmeter

Overview WJLUGB Intelligent Vortex flowmeter is based on the principle of Karman vortex flowmeter new type of fluid vibration, it has a wide measurement range, pressure loss, stable performance, high accuracy and installation, ease of use; widely used Closed industrial pipeline liquids, gases and steam media measurement volume and mass flow. Second, the functional characteristics and technical parameters 1, measuring medium: gas, liquid and steam. 2, double LCD also shows the cumulative flow and instantaneous flow; 3, the internal lithium battery-powered, no external power supply; 4, micro-power design, two + 3V lithium battery can work continuously for more than a year and a half; 5, inductive sensors elements are not directly in contact with the measured medium, stable performance and high reliability. 6, no moving parts within the sensor, the structure is simple and solid, the pressure loss is small, a small amount of dimensional expansion, long service life. 7, wide range of 10: 1 to 15: 1. 8, measuring range: normal operating range, Reynolds is 20,000-7,000,000; the output signal from the liquid temperature, pressure, viscosity and components affected. Measurement possible, Reynolds 8,000-7,000,000. 9. Accuracy class: ± 1.0% liquid indicated value; ± 1.0% gas, indicated value; ± 1.5% steam, indicated value. 10, the output signal: a.OC gate pulse output; b current 4-20mA (two-wire / three-wire system). 11, the power supply voltage: + 24VDC (signal output provided when needed). 12, medium temperature: Ordinary a.-40 ℃ ~ + 130 ℃; b.-10 ℃ ~ + 250 ℃; 13, working pressure: 0-2.5Mpa, clamping flange connection (Note: Users should be provide additional pressure levels, to be customized). 14, the pressure loss: ΔPΔP = 1.079 * 10-6 * ρ * v2 (formula: ΔP: Pressure loss kpa; ρ: the measured medium density kg / m3; V: the measured medium velocity m / s). 15, shell material: carbon steel; stainless steel (1Cr18Ni9Ti). 16. Specifications (pipe diameter) 20,25,32,40,50,65,80,125,150,200,250,300 (greater than a diameter of the plug-DN300). 17, Ambient temperature -25 ℃ ~ + 55 ℃; humidity ≤85% RH. 18. Type of protection: flameproof; proof mark; iaIIcT4.
