I. Overview JYLDE series of intelligent electromagnetic flowmeter electromagnetic flowmeter is an electromagnetic induction type flow meter, which consists of sensors and intelligent signal converter. It can measure all kinds of conductive liquid volume flow, measured media, including sewage, water, water, acid, alkali, salt and other corrosive liquids, raw water, cooling water, pulp, mud, coal slurry, pulp, molasses, corn pulp, fiber pulp, grain syrup, lime, hydrogen peroxide, water, beer, wort, milk and a variety of beverages and other conductive liquid and solid-liquid two-phase fluid. The products are mainly used in industry and municipal environmental protection, water conservancy and other petrochemicals, iron and steel, power, metallurgy, textile, food, pharmaceutical, paper and so on. Second, the technical parameters of the electromagnetic flowmeter nominal diameter (mm) (special specifications can be customized) pipeline tetrafluoroethylene lining: DN10 ~ DN1200 pipeline rubber lining: DN40 ~ DN1200 flow direction: positive and negative, the net flow turndown ratio: 150: a repeatability error: ± 0.1% of measured value Accuracy: Pipeline: 0.2-0.5% level measured medium temperature: ordinary rubber lining: -20 ~ + 60 ℃ high temperature rubber lining: -20 ~ + 90 ℃ PTFE Lining: -30 ~ + 100 ℃ high temperature tetrafluoride lining: -20 ~ + 180 ℃ Rated working pressure: (high pressure can be customized) DN6-DN80: ≤1.6MPa DN100-DN250: ≤1.0MPa DN300-DN1200: ≤0.6MPa flow rate range : 0.1-15m / s Conductivity range: the measured fluid conductivity ≥5μs / cm URL: www.jyllj.com Current output: load resistance 0 ~ 10mA: 0 ~ 1.5kΩ 4 ~ 20mA: 0 ~ 750 kΩ digital frequency output : output frequency limit can be set with optical isolation transistors in the 1 ~ 5000HZ bidirectional open-collector output. External power supply is turned ≤35V maximum collector current of 250mA Power supply: AC220V, DC24V or 3.6V batteries require straight pipe length upstream ≥5DN, downstream ≥2DN connection: flange connection between each meter and piping, France Lan connection size shall comply with the provisions of GB11988 proof grade: mdIIBT4 Protection class: IP65, IP68 special order up to ambient temperature: -25 ~ + 60 ℃ Relative humidity: 5% to 95% of the total power consumption: less than 20W
