Intelligent Electromagnetic Flowmeter - Split

Split split electromagnetic flowmeter electromagnetic flowmeter LDE LDE split electromagnetic flowmeter to measure the inner tube is a conductive medium volume flow induction meter according to Faraday's law, embedded microcontroller technology, digital excitation, while the electromagnetic flowmeter uses the CAN fieldbus, is a national initiative, technology has reached domestic leading level. JLLDE electromagnetic flowmeters to meet live shows while you can also output 4 ~ 20mA current signal for recording, regulation and control, is now widely used in chemical industry, environmental protection, metallurgy, pharmaceutical, paper, water supply and drainage and other industrial technology and management department. JLLDE electromagnetic flowmeters measure the flow of conductive liquids in addition, it can also measure the phase fluids, high viscosity fluid and salts, acid and alkali liquid volume flow. Features ◆ instrument simple structure, reliable, no moving parts, long working life. ◆ No closure blocking parts, no pressure loss and fluid loading. ◆ no mechanical inertia, fast response, good stability, can be used in automatic detection, regulation and program control system. ◆ measuring not affect the accuracy of the measured media types and temperature, viscosity, density, pressure and other physical parameters. ◆ different combinations with PTFE lining or rubber material and Hc, Hb, 316L, Ti and other electrode materials can be adapted to the needs of different media. ◆ available pipeline, plug-flow models. ◆ EEPROM memory used to measure data storage secure and reliable operation. ◆ have the integration and separation of two types. ◆ High-resolution backlit LCD display. Technical parameters ◆ meter accuracy: Pipeline 0.5, 1.0; Plug-in 2.5 ◆ Measuring medium: conductivity is greater than 5μS / cm various liquids and liquid-solid two-phase flow. ◆ flow rate range: 0.2 ~ 8m / s ◆ Working pressure: 1.6MPa ◆ Ambient temperature: -40 ℃ ~ + 50 ℃ ◆ Medium temperature: ≤180 ℃ teflon-lined rubber material lining ≤65 ℃ ◆ Explosion-proof mark: ExmibdⅡBT4 ◆ Explosion No.: GYB01349 ◆ external magnetic interference: ≤400A / m ◆ shell protection: Integrated type: IP65; Separate: Sensor IP68 (5 meters underwater, only rubber lining) converter IP65 ◆ Output signal: 4 ~ 20mA .DC, load resistance 0 ~ 750Ω ◆ communication output: RS485 or CAN bus ◆ Electrical connection: M20 × 1.5 thread, φ10 cable hole ◆ Power supply voltage: 90 ~ 220V.AC, 24 ± 10% V.DC ◆ maximum power consumption : ≤10VA instrument selection ◆ measuring range of electromagnetic flowmeters for general industrial use confirm the measured medium flow rate 2 ~ 4m / s is appropriate, in exceptional circumstances, the minimum flow rate should be not less than 0.2m / s, the maximum should not exceed 8m / s. If the medium contains solid particles, commonly used flow rate should be less than 3m / s, to prevent excessive friction lining and the electrodes; for viscous fluid velocity choose more than 2m / s, a higher flow rate helps to automatically eliminate electrode attached to the stick Lag substrates, help improve the measurement accuracy. Q has been determined in the range of conditions, you can determine the size of the flow meter diameter D of the flow velocity V of the above range, the value calculated by the following formula: Q = πD2V / 4 Q: flow rate (m / h) D:? Pipe diameter ?? V: flow velocity (m / h) Q electromagnetic flowmeter range should be greater than the expected maximum flow rate value, and the normal flow value slightly larger than 50% of full scale flow meter is appropriate. ◆ reference flow range diameter (mm) flow range (m3 / h) Diameter (mm) flow range (m3 / h) φ15 0.06 ~ 6.36 φ450 57.23 ~ 5722.65 φ20 0.11 ~ 11.3 φ500 70.65 ~ 7065.00 φ25 0.18 ~ 17.66 φ600 101.74 ~ 10173.6 φ40 0.45 ~ 45.22 φ700 138.47 ~ 13847.4 φ50 0.71 ~ 70.65 φ800 180.86 ~ 18086.4 φ65 1.19 ~ 119.4 φ900? 228.91 ~ 22890.6 φ80 1.81 ~ 180.86 φ1000? 406.94 ~ 40694.4 φ100 2.83 ~ 282.60 φ1200 553.90 ~ 55389.6 φ150 6.36 ~ 635.85 φ1600 723.46 ~ 72345.6 φ200 11.3 ~ 1130.4 φ1800 915.62 ~ 91562.4 φ250 17.66 ~ 176.25 φ2000 1130.4 ~ 113040.00 φ300 25.43 ~ 2543.40 φ2200 1367.78 ~ 136778.4 φ350 34.62 ~ 3461.85 φ2400 1627.78 ~ 162777.6 φ400 45.22 ~ 4521.6 φ2600 1910.38 ~ 191037.6 meter Model Description: Specifications Code Description JL Jinling enterprise standard instrument types LDE intelligent electromagnetic flowmeter meter electromagnetic flowmeter types LDM common path codes -XXX Example: 100 means DN100, after I expressed access path if the plug-in, then the AI ??represents an adjustable insert electrodes form -1 2 standard fixed knife 3 removable replaceable electrode material platinum pt 2 0 1 stainless steel Hastelloy B (HB) 3 Ta Ta 4 Ti 5 Titanium Hastelloy C (HC) electrode material 3 urethane rubber neoprene 4 5 F4 6 F46 7 F40 8 P0 9 PPS rated pressure (MPa) -4.0 DN10-80 1.6 DN100-150 1.0 DN200-1000 0.6 DN1100-2000 0.25 DN2200 Operating temperature E <80oC H <180oC grounding ring grounding ring 1 -0 not have Grounding ring protection class 0 IP65 1 IP68 converter integrated Type 0 1 split newsletter 0 No 1 RS-485 2 Hart 3 PA bus 4 FF bus -0 housing material stainless steel tables flange 0 1 1 stainless steel installation companion flange 0 without 1 with 0 220VAC 1 24VDC power supply range of the instrument (XXX) Example: (2000) that corresponds to the maximum flow rate of 20mA 2000M3 / h
