Description
AEM-Electromagnetic Flowmeter for DN15~DN3000
Features and uses
★ Independence: The measurement is not affected by changes in liquid density,
viscosity, temperature, pressure and conductivity;
★ Energy saving and low fault: no moving and blocking parts in the measuring
tube, no blockage, no loss;
★ Widely used: conductive liquid, containing fiber, solid particles,
suspended liquid;
★ Easy installation: low requirements for straight pipe section (first 5D
after 2D);
★ Protection IP68, IP66: DN15~ DN1200, intrinsic immersion structure;
★ High intelligence: backlit LCD display, high integration, double isolation,
parameter setting, menu operation. Chinese display, memory function, reliable
programming, password lock and access, small signal cutting, non-linear
correction, two-way measurement;
★ SMT technology: intelligent self-test and self-diagnosis function, upper
and lower limit alarm, excitation alarm, air traffic control alarm;
★ SMART excitation: low power consumption, zero stability, no drift, reliable
operation;
★ Multiple output: current output (4~20) mA current, frequency
(1~5000)Hz,RS485/Modbus, HART;
★ Lining and electrode: lining and electrode materials have a variety of
choices, suitable for different media;
★ Ultra-low EMJ switching power supply: large power supply range, good
anti-interference performance;
