Insertion Electromagnetic Flowmeter DWM 1000/2000 DWM Insertion Electromagnetic Flowmeter operates based on Faraday's law of electromagnetic induction and is used to measure the flow of conductive liquids, colloids, and suspensions. The DWM1000 electromagnetic flow switch features a two-wire switch output; the DWM2000 electromagnetic flow transmitter outputs a 4-20mA current signal; and the DWM2000D model includes LCD display and setting functions. Product Features Can measure pipelines with diameters ≥ DN50 (2") Easy installation and operation, low maintenance cost, low power consumption No moving parts, minimal pressure loss, maintenance-free Electronic components can be replaced during measurement Wide range of applications, such as sewage, cold water, and tap water treatment Extended models available for pipeline diameters greater than DN1000 Technical Specifications Power Output DWM 1000: Two-wire system DWM 2000: 4-20mA current output Voltage 48-250VAC(VDC) 50/60Hz 24VDC (20-30VAC) Power Consumption ≤5mA ≤5mA Output Normally open or normally closed Passive current output 4~20mA Time Constant 0.1-9.9m/s 1/2/3/4/5/6/7 or 8m/s Conductivity ≥ 20μS/cm (μmho/cm) Working Pressure ≤ 25bar Medium Temperature -25℃~+150℃ Ambient Temperature -25℃~+60℃ Material Stainless steel, ceramic, platinum (electrode), cast aluminum (housing) Pipeline Installation Standard Size ≥DN50 (2") Connecting Sleeve With G1 thread Straight Pipe Section Inlet: 10 times the diameter; Outlet: 5 times the diameter, depending on flow conditions Protection Level (Indicator) Standard type IP 66; Submersible type IP 68
