AEM-Electromagnetic Flowmeter for DN15~DN3000
Electromagnetic flowmeter is a type of flowmeter that utilizes Faraday’s electromagnetic induction principle. This product adopts the latest international technology and is widely used in industries such as chemical, power, metallurgy, drainage, sewage treatment, liquid high-pressure metering, medicine, food, environmental protection, etc. It is used to measure the volume flow rate of conductive liquids and slurries in closed pipelines.
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;
