product description The working principle of the insertion electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. In an electromagnetic flowmeter, the conductive medium in the measuring tube is equivalent to that in the Faraday test. Conductive metal rod, two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows, an induced voltage is generated. Two electrodes inside the pipe measure induced voltage. The measuring tube is electromagnetically isolated from the fluid and the measuring electrode by means of a non-conductive lining. Features: 1. Simple structure and firm installation; 2. No moving parts, long service life; 3. Reliable measurement and strong anti-interference ability; 4. Small size, light weight, easy installation and low maintenance; 5. The measurement range is large, and the measurement is not affected by changes in temperature, density, pressure, viscosity, conductivity, etc.; 6. Zero pressure loss; 7. It can be installed and disassembled under the condition of continuous flow, which brings convenience to the user's maintenance; 8. Compared with the general electromagnetic flowmeter, the manufacturing cost and installation cost are lower, and it is especially suitable for the flow measurement of large and medium diameter pipelines. Technical parameter: Nominal diameter (mm): DN100-700 Velocity range: 0.5m/s-10m/s Accuracy: ±1.5%FS; ±2.5%FS; ±5.0%FS; Conductivity: ≥20us/cm Straight pipe section: front 5DN, rear 3DN Medium temperature: -20℃~+90℃ Ambient temperature: -20℃~+60℃ Pressure resistance: 1.6MPa Protection class: IP65 (integrated), IP68 (split) Electrode material: 316L stainless steel Output signal: 4-20mA; RS485; Hart protocol; Modbus protocol; Sensor Material: Stainless Steel Working power: 220VAC, tolerance 15% or 24VDC, ripple s5% power 6.5W Pressure rating: ≤1.6MPa
